Baseball in the United States

Major League Baseball is divided into two leagues: the American League and the National League, each of which is further divided into three divisions: East, Central, and West. The American and National League used to be separate entities: the American League successfully challenged the established National League and was sometimes referred to as the "Junior Circuit". For most of Major League Baseball's history, teams from the two leagues only met in the World Series at the end of each season. However, the distinctions between the leagues have been erased more and more. Teams of the different leagues face now each other several times throughout the season. The mystique has been removed from the competition between teams as representatives of their league or from the All-Star Game which is still organized based on league.

Before 2022, the main distinction between the two leagues was that the designated hitter was used only in the American League; the National League required pitchers to bat along with the other fielders. In games that involved teams from both leagues (called "interleague" games), the home team's rules were used. The NL used the DH in the abbreviated COVID-19 season of 2020, but returned to its non-use in 2021. As part of the settlement of a labor dispute in the 2021–22 offseason, the DH was made a permanent feature in the National League.

Here is a run-down of all the teams and their respective stadiums:

• Baltimore Orioles - Oriole Park at Camden Yards - Baltimore, Maryland (in South Baltimore). Opening in 1992, Camden Yards is notable for being the first of the "retro" ballparks in the major leagues: modern stadiums whose designs hearken back to classic, early-20th century ballparks. The success of Camden Yards sparked a wave of new ballpark construction across the country, but it's still regarded as one of the best. Nearby is the Babe Ruth Museum, preserving the house where the Great Bambino himself was born. The "O's" have very enthusiastic fans, who are known for yelling out the "O!" in the penultimate line of the national anthem.
• Boston Red Sox - Fenway Park - Boston, Massachusetts (in Fenway). The oldest active ballpark in the major leagues, Fenway Park opened in 1912 and is a celebrated stadium that has acquired certain quirks which are legendary among baseball fans. The most noted of these is the Green Monster, a particularly tall section of the left field wall that's, of course, painted green. The ballpark is relatively small by major league standards, tucked into an urban neighborhood of restaurants, taverns, and souvenir stores. Boston's famously rowdy fans (the "Red Sox Nation") are fiercely loyal to their team and their rivalry with the Yankees is legendary, ranking as arguably the most intense in American sports.
• New York Yankees - Yankee Stadium - New York City, New York (in the Bronx). Though not "The House That Ruth Built" stadium of old (which was replaced by a city park), the design of the new Yankee Stadium just across the street pays homage to the original in its design, both inside and out. An on-site museum covers the history of one of the most storied teams in baseball, and Monument Park in center field contains plaques dedicated to great players from the team's past. The Yankees are noted (and often vilified) for their frequent postseason appearances, with their record 27 championships unmatched in North American professional sports.
• Tampa Bay Rays - Tropicana Field - Saint Petersburg, Florida. After struggling as an expansion team, the Rays managed to rise to be a competitive force in the fierce American League East. They play in the uninspiring Tropicana Field, the only ballpark in MLB with a fixed dome roof and one of only four to still use artificial turf on the field instead of actual grass. On-site is a museum dedicated to Red Sox legend Ted Williams, who retired to the Tampa area, with exhibits and memorabilia on some of the best hitters in baseball history. Another highlight is a touch tank beyond the right-center field wall, where fans can touch and feed live stingrays.
• Toronto Blue Jays - Rogers Centre - Toronto, Ontario (in the Entertainment District), Canada. The only MLB team playing in Canada, the Blue Jays play in Rogers Centre, a massive stadium with a retractable roof (to protect against the colder Toronto weather) that sits in the shadow of the iconic CN Tower. Within the stadium is a hotel with rooms that overlook the field.

• Chicago White Sox - Guaranteed Rate Field - Chicago, Illinois (in Bridgeport). The White Sox play on the South Side of town in Guaranteed Rate Field, commonly known as Comiskey Park (the name of the old White Sox ballpark). While the stadium lacks the charm of its crosstown National League rival, tickets here are easier to get and the fans are no less loyal. There are a couple of unique features that are carry-overs from the old stadium: one is a shower and a pair of "rain rooms" for fans to cool off on hot days, and the other is the "exploding" scoreboard with its distinctive pinwheel signs that light up and shoot off fireworks when the White Sox hit a home run.
• Cleveland Guardians - Progressive Field - Cleveland, Ohio (in Downtown). Known as the Cleveland Indians until 2021. Widely regarded as one of the better ballparks in the league, Progressive Field was a more modern take on the "retro" ballpark design when it was constructed. The interior offers a splendid view of the Cleveland skyline.
• Detroit Tigers - Comerica Park - Detroit, Michigan (in Downtown). Adjacent to Detroit's theater district, the Tigers' stadium has a number of interesting features, notably excellent views of Downtown Detroit, statues of tigers which growl after a Tiger home run, a fountain behind center field, and plenty of tributes to one of baseball's oldest and most storied teams, including statues of former Tiger greats such as Willie Horton, Hank Greenberg, and Ty Cobb.
• Kansas City Royals - Kauffman Stadium - Kansas City, Missouri. The Royals have heated up lately; after going nearly thirty years without a playoff appearance, they staged a stunning World Series run in 2014 and were crowned champions in 2015, much to the joy of their fans. They play in Kauffman Stadium on the edge of the city, one of the few remaining examples of 1960s-era modernist stadiums and still one of the best examples of modernist stadium design, with a fountain beyond the right field wall that sends jets of water high into the air.
• Minnesota Twins - Target Field - Minneapolis, Minnesota (in Downtown). The Twins play in Target Field, a marvelous ballpark with plenty of amenities for fans and splendid views of Downtown Minneapolis.

• Houston Astros - Minute Maid Park - Houston, Texas (in Downtown). Members of the National League for their first 50 seasons, the Astros moved to the American League with the start of the 2013 season, and won their first World Series in 2017 and added a second in 2022. However, the 2017 victory and their 2019 World Series appearance were tainted after it was revealed that the team was illegally using technology to steal pitching signs, and the Astros are now by far the most reviled team in MLB. Their stadium is full of bells and whistles, with an entrance through what was once a train station, a retractable roof that protects fans from Houston's humid weather, various oddities in the design of the outfield fence, and a miniature train that moves along the exterior wall past left field whenever the Astros hit a home run.
• Los Angeles Angels - Angel Stadium of Anaheim - Anaheim, California. For many years, the Angels were a running joke in baseball, even inspiring a film by their then-owners Disney about their misfortune on the field. A World Series victory in 2002 turned the team's fortunes around for a time, and they were frequent contenders for the playoffs into the 2010s. However, the Angels have since fallen on hard times, having finished with a losing record in every season since 2016 despite the presence of two of the game's biggest names in outfielder Mike Trout and more recently Japanese two-way superstar Shohei Ohtani (who left for the LA area's other team, the Dodgers, as a free agent after the 2023 season). Their stadium is most noteworthy for the giant haloed "A" that stands in the parking lot as well as sitting within spitting distance of Disneyland. If you're lucky enough to witness an Angel home run, geysers and fireworks erupt out of a small mountainside beyond left field.
• Oakland Athletics - RingCentral Coliseum - Oakland, California. A regular contender for the playoffs, the A's play in the Coliseum, the last of the multi-purpose "cookie-cutter" stadiums built in the 1960s remaining in the major leagues (the NFL Oakland Raiders played here before their 2020 move to Las Vegas). Due to this, there are oddities in the design of the field, such as the most foul territory of any MLB field by a large margin. With the A's lease on the Coliseum expiring at the end of the 2024 season, and plans for a new stadium in Oakland having fallen into development hell, the team is now planning a move to Las Vegas, having purchased land near the Las Vegas Strip in April 2023 for a new park. After the 2024 season, the team will move to a minor-league park in Sacramento (more specifically West Sacramento) while the Vagas ballpark is being built.
• Seattle Mariners - T-Mobile Park - Seattle, Washington (in Sodo). Built on former industrial land south of Pioneer Square (and indeed, there's still quite a bit of industry in the neighborhood), the modern retro-style T-Mobile Park (renamed from Safeco Field in 2019) has some interesting features, including a retractable roof to protect against the regular Seattle rain and quite possibly the best selection of food of any ballpark in the country.
• Texas Rangers - Globe Life Field - Arlington, Texas. In the early 2010s the Rangers emerged as a competitive force in the American League, but fell into a serious dry spell, with six consecutive losing seasons, before making the 2023 postseason as a wild card and going all the way to their first-ever World Series win. They opened the 2020 season in the new Globe Life Field, directly across the street from their former home of Choctaw Stadium, with both lying roughly between the Dallas Cowboys' stadium and a Six Flags theme park. The new park has a thoroughly modern retractable roof and air conditioning, but otherwise is much like their old park—a retro-style ballpark with plenty of nods to the classic ballparks of old.

• Atlanta Braves - Truist Park – Cumberland, Georgia (just outside Atlanta). The Braves are one of the most prominent franchises in baseball, owing in large part to the national coverage that used to be given by the locally headquartered TBS network. Braves fans are known for their use of the "Tomahawk Chop," a war chant accompanied by a rhythmic "chopping" motion made by the arm. The team plays in one of MLB's newest parks, opened for the 2017 season as SunTrust Park, and renamed in 2020. Besides the typical bells and whistles of a 21st-century ballpark, fans seated behind home plate are treated to views of the Atlanta skyline.
• Miami Marlins - LoanDepot Park – Miami, Florida (in Little Havana). One of the newest stadiums in baseball, LoanDepot Park (originally Marlins Park) was the first new ballpark to buck the retro trend since Camden Yards started it in the first place. It switched from grass to artificial turf in 2020. LoanDepot Park is a thoroughly contemporary structure of glass and steel, with a retractable roof and air conditioning offering relief from the humid weather, a nightclub and a swimming pool beyond the outfield (although you have to pay to be in a special section to use it), a bobblehead museum, and colorful art elements throughout. The stadium sits in Little Havana, a Latin American neighborhood with plenty of local shops and restaurants.
• New York Mets - Citi Field – New York City, New York (in Flushing, Queens). Standing in marked contrast to the crosstown Yankees, the Mets have always had a hard go of it, but the faithful continue to turn out to cheer on their lovable underdogs. They play in a fairly new ballpark with a facade that pays homage to Ebbets Field, the classic ballpark that was once home to the Brooklyn Dodgers. If the Mets hit a homer, look for the Home Run Apple, a huge apple that rises out of the center field wall. The Mets are also known for what may be the most popular mascot in baseball, Mr. Met, a man with a baseball for a head. Citi Field sits adjacent to Flushing Meadows-Corona Park, with its museums and the famous Unisphere.
• Philadelphia Phillies - Citizens Bank Park – Philadelphia, Pennsylvania (in South Philly). The oldest single-city team in baseball, the Phillies have overcome their long championship drought to become a competitive force in the NL East, most recently with a losing World Series appearance in 2022. Citizens Bank Park is a beloved retro-style park, with features like a sign in the shape of the Liberty Bell that lights up and "rings" after a Phillies home run and Ashburn Alley, a promenade beyond center field that holds restaurants and memorabilia from Phillies history. The Phillies also have one of the most popular (and strangest) mascots in baseball, the Phillie Phanatic, a big, furry, green creature who engages in various antics on the field.
• Washington Nationals - Nationals Park - Washington, D.C. (on the Waterfront). The newest team in the major leagues (i.e., in their current location, though not the newest franchise), the Nationals are the latest incarnation of professional baseball in D.C. and have quickly proven to be a favorite of the locals. Their ballpark sits on the south side of town in a rapidly gentrifying neighborhood near the Navy Yard.

• Chicago Cubs - Wrigley Field - Chicago, Illinois (in Lakeview). Few teams can claim the storied history or agony of defeat that the Cubs can, but the curse has come to an end: after going over a hundred years without a championship and not even an appearance in the World Series since 1945, the Cubs finally won the championship in 2016. But win or lose, a game at Wrigley Field is undoubtedly one of the greatest experiences in baseball and has been celebrated in many films. The ballpark, one of only two remaining classic ballparks (the other being Fenway Park), is renowned and beloved for its many unique features, from its bright red marquee sign out front, to the ivy-covered outfield walls, to the rooftop seats atop the buildings across the street, and to the surrounding neighborhood which embraces game day to the fullest.
• Cincinnati Reds - Great American Ball Park - Cincinnati, Ohio. The oldest professional team in baseball, the "Big Red Machine" (a nickname earned due to their powerful hitting lineup in the 1970s) have long been entertaining their loyal fans. The Reds' riverfront ballpark is full of nods to the history of the team, including the Cincinnati Reds Hall of Fame and an extensive museum.
• Milwaukee Brewers - American Family Field - Milwaukee, Wisconsin. The Milwaukee faithful pour into American Family Field, until 2020 known as Miller Park, which sports a fan-shaped retractable roof and plenty of nods to the city's brewing heritage. A highlight is the "Sausage Race" during the 6th inning, when a group of sausage mascots race around the field. Another mascot, Bernie Brewer, slides down a plastic yellow slide beyond left field after every Brewer home run.
• Pittsburgh Pirates - PNC Park - Pittsburgh, Pennsylvania (on the North Side). The Pirates have had a hard go of it over the last couple of decades, but lately the "Buccos" have found new life, ending a 20-year string of losing seasons with a playoff berth in 2013 and proving strong competitors since. Their stadium is widely considered one of the best in the major leagues, sitting on the city's superb riverfront with a breathtaking view of the Pittsburgh skyline.
• St. Louis Cardinals - Busch Stadium - St. Louis, Missouri. A regular feature in the playoffs, the Cardinals command a huge and enthusiastic fanbase in this diehard sports town. They play on the south side of the city's downtown, with an excellent view of the skyline with its famed Gateway Arch. An impressive hall of fame for the Cardinals is on-site, a testament to the winningest team in the National League (in terms of World Series championships).

• Arizona Diamondbacks - Chase Field - Phoenix, Arizona. Despite their short history, the Diamondbacks have proved to be a surprisingly strong team in the NL West. Chase Field sports a retractable roof, air conditioning and even a swimming pool beyond the center-right field wall (although the pool is only accessible as part of a luxury suite), must-haves in the blazing Phoenix heat. It switched from grass to artificial turf in 2019.
• Colorado Rockies - Coors Field - Denver, Colorado. Widely regarded as one of the best ballparks in the major leagues, Coors Field is a retro-style ballpark that has earned a reputation as a home run-friendly park, owing in large part to the dry air and high altitude. The ballpark sits on the edge of the LoDo neighborhood of Downtown Denver, popular for its restaurants and bars as well as the home of the National Ballpark Museum, with a fantastic collection of artifacts from many classic ballparks.

• Los Angeles Dodgers - Dodger Stadium - Los Angeles, California (in Elysian Park). The Dodgers are one of the most famous and successful baseball teams of all time, with a long history in Los Angeles since their move here from Brooklyn in the 1950s. Their ballpark, carved out of a hill north of Downtown L.A., is the largest baseball stadium in the world by seating capacity and has earned a reputation as a pitcher's park, and is also perhaps the best remaining example of the modernist stadiums built in the 1960s.
• San Diego Padres - Petco Park - San Diego, California (in Downtown). Sandwiched into Downtown San Diego near the harborfront and the historic Gaslamp Quarter district, Petco Park has a number of unique elements, including a historic brick warehouse incorporated into the left-field seats and a grassy lawn beyond the center field wall that's open as a public park on non-game days. The stadium has gained a distinction as the most pitcher-friendly park in the major leagues, due to the dense, humid air along the nearby coast.
• San Francisco Giants - Oracle Park - San Francisco, California (in SoMa). One of the oldest teams in baseball, having played in New York prior to their move to California in the 1950s, the Giants play in Oracle Park (renamed from AT&T Park in 2019), a popular retro-style ballpark looking out on the bay. A small cove next to the park is the frequent target of home runs, which makes it popular for kayakers hoping to snag a souvenir. The Giants haven't always had an easy time of it since moving to San Francisco, but a trio of recent World Series victories have made them a force to be reckoned with.

Prior to the start of the regular season, the Major League teams participate in a series of exhibition games through the month of March. Spring Training is an opportunity to get a lot closer to your favorite players than would be possible during the regular season. For climate-related reasons, all Spring Training games are held in Arizona or Florida, the Cactus League and Grapefruit League respectively.

Held every year in early to mid-July, the All-Star Game is an exhibition game pitting the best players in the American League against the best of the National League. Wherever it is held, the All-Star Game is the centerpiece of a week-long celebration, which includes a fan fest and a home run derby. The league determines the location of the game in advance, and tickets are very expensive.

Upcoming All-Star Games:

• 2024: July 16 at Globe Life Field in Arlington, Texas
• 2025: Date TBA at Truist Park in the Cumberland area of Cobb County, just outside Atlanta, Georgia
• 2026: Date TBA at Citizens Bank Park in South Philadelphia. This site was announced years in advance, as that year will mark the 250th anniversary of U.S. independence.

Every October, the leaders of each of the three divisions plus three Wild Card teams in each league compete in the postseason (MLB used the word "playoff" only to refer to very rare tiebreaker games used to determine playoff berths; said games were eliminated after 2021). Each league plays in a knockout tournament with three rounds. The first round, known as the Wild Card Round, consists of best-of-three series (i.e., a maximum of three games). This is followed by the Division Series (best-of-five) and the League Championship Series (best-of seven). The LCS winners advance to the World Series, in which the AL and NL winners play a best-of-seven series.

For most of the existence of professional Baseball, rail was the main mode of travel for fans and teams alike to get to road games. With the move of the Dodgers and the Giants from their erstwhile New York homes to the West Coast in the fifties, most teams switched to air travel as their primary mode of transport and fans visiting road games eventually followed suit. Details for getting into each city are in the individual city articles. All major league teams are in major cities, with excellent air and road access. In some parts of the country it is possible—with careful planning—to hop from city to city and see multiple stadiums in the course of several days. This is easiest on the Eastern Seaboard (Boston/New York City/Philadelphia/Baltimore/Washington, D.C.) with convenient road and rail access and relatively short distances between cities. With a car, this can also easily be done in the Midwest (Pittsburgh/Cincinnati/Cleveland/Detroit/Toronto or Minneapolis/Milwaukee/Chicago/St. Louis) or California (San Diego/Anaheim/Los Angeles/Oakland/San Francisco). Outside these areas, however, the distances between cities are simply too great to make this feasible except by airplane.

Parking and accessibility varies considerably between ballparks. In general, stadiums in cities in the Northeast and in the Midwest will see heavy traffic and limited, expensive parking, while those in the South and the West will have ample parking, though there are exceptions to this. All stadiums charge for parking, generally in the range of $10-$25 depending on the individual stadium and how close you park to the ballpark, with certain high-demand teams charging more.

For the most part, all stadiums have made a strong attempt to provide enough parking, but in a few cases—namely Boston, New York City, Washington, D.C., Chicago, Toronto and San Francisco—parking is such a challenge that it's preferable to use the local mass transit systems, which are well-developed in these cities and do a good job serving games.

Part of the thrill of attending a game is catching a foul ball, or even a home run ball. Fans will sit in a part of the park specifically geared to catching these. When the ball approaches, it can deflect of hands like a pinball so you never know where it will land. If you are trying to catch a foul ball or a home run, be respectful of those around you and don't do anything to hurt yourself or someone else. Also keep in mind that in some ballparks, such as Wrigley Field, local tradition calls for home run balls hit by the visiting team to be thrown back.

In the Women's College World Series of NCAA softball (see "Softball" below), a unique tradition is that a home run ball is taken by the ushers and given to the family of the player who hit it (or, if the player's family is not present, to that team's coaches, who will present it to the family later). People who catch home run balls at that event are given other memorabilia, such as unused game balls, in exchange for the home run ball.

Have patience. The game can move slowly, especially if you aren't familiar with it.

• All teams have a team store at the stadium to purchase jerseys, hats, and other memorabilia.
• Team merchandise can often be purchased at nearby stores for less than what the stadiums charge.

• One of the exciting things about going to different ballparks is sampling foods that only they have. All stadiums have a plethora of eating options (mostly fast food) from standard ballpark fare like hot dogs, hamburgers and nachos to more specialized eats like sausages in Milwaukee, fish tacos in San Diego, and sushi in Seattle. Prices usually run between $3-$5 for hot dogs and $10 or more for specialized food like barbecue or chicken. Ballpark food is usually more expensive than comparable food sold at restaurants.
• If you have dietary restrictions (halal, kosher, vegan, gluten-free) you should check ahead of time to see what is available.

• Most baseball stadiums sell beer, albeit at prices higher than bars or liquor stores. Some ballparks also serve wine or cocktails. For drinkers of non-alcoholic beverages, sodas or bottled water are also available.

• Smoking is prohibited in most locations in most stadiums. Some may ban it in all locations.
• Many stadiums prohibit coolers, large bags, backpacks, plastic or glass bottles, cans and video cameras from the stadium. Check specific stadium policies before attending. All stadiums will ban knives, firearms, fireworks, and noisemakers.
• Don't be loud or obnoxious to other fans: A common crowd maneuver is the "wave", in which to support the team fans stand up and immediately sit back down, with the motion progressing around the bleachers, creating said "wave". However, ask most hardcore baseball fans and they will tell you they despise the wave, as it causes obstruction of eyesight towards the action on-field.

Rookie Level teams play in the spring training complexes of their parent teams. Admission is not charged, but as such concessions are not sold. Major league clubs are allowed to field more than one team at this level.

• Arizona Complex League
• Florida Complex League

Held in Omaha every June, the MCWS pits eight teams against each other. The tournament is divided into two four-team double-elimination brackets, with the winners of each bracket then playing a best-of-three series to choose the NCAA Champion. Tickets range from $28-33 for reserved seats and $11 each or $80 for ten for general admission (non-guaranteed) seats. Tickets generally go on-sale in May.

These are NCAA-sanctioned summer baseball leagues, partially funded by Major League Baseball, drawing from college-age players. A high percentage of drafted players come from these leagues.

• Cape Cod Baseball League, Cape Cod, Massachusetts. Over 110 years of history. One in seven Major League Baseball players played in this league.
• Central Illinois Collegiate League, Illinois.
• Great Lakes Summer Collegiate League.
• New York Collegiate Baseball League, New York.
• Atlantic Collegiate Baseball League, Pennsylvania, New York and New Jersey.
• Southern Collegiate Baseball League.
• Valley Baseball League, Virginia.
• Florida Collegiate Summer League, Florida.
• Coastal Plain League, North Carolina, South Carolina, and Virginia.

Though it's not an NACSB-sponsored league, the Alaska Baseball League is a collegiate summer league that's worthy of special note as the host of the Midnight Sun Game, an experience that's unique in the sport of baseball—it's played on the summer solstice in the midnight sun, beginning around 11PM, at Growden Memorial Park in Fairbanks, the northernmost baseball stadium in the world. The ABL boasts over a century of history and such famous alumni as Barry Bonds, Jason Giambi, and Mark McGwire.

Held every year in South Williamsport, Pennsylvania, over 10 days ending on the last Sunday of August, the LLWS pits 20 teams of 11–12 year olds from around the world in a tournament to prove the best team. It's very popular among people of all ages, and the atmosphere is electric for every game. Tickets are available on a first-come-first-served basis for all games except the World Championship Game. Those tickets are distributed by a lottery system, but seating beyond the stadium fences is always available.

The biggest event in American softball is the Women's College World Series, the final phase of the NCAA Division I championship. Held each June at USA Softball Hall of Fame Stadium in Oklahoma City, its format is almost identical to that of its men's counterpart, featuring eight teams in a double-elimination tournament until two teams remain, at which point the survivors play a best-of-three championship series. The major difference is that the WCWS format allows any two of the participating teams to advance to the championship series.
