The Athletics (often referred to as the A's) are an American professional baseball team currently and temporarily based in West Sacramento, California. The Athletics compete in Major League Baseball (MLB) as a member club of the American League (AL) West Division. The team plays its home games at Sutter Health Park in West Sacramento, and is approved to relocate to the Las Vegas metropolitan area for the 2028 season. The franchise's nine World Series championships, 15 pennants, and 17 division titles are the second most in the AL after the New York Yankees.
One of the AL's eight charter franchises, the team was founded in 1901 as the Philadelphia Athletics. They won three World Series championships in 1910, 1911, and 1913, and back-to-back titles in 1929 and 1930. The team's owner and manager for its first 50 years was Connie Mack, and Hall of Fame players included Chief Bender, Frank "Home Run" Baker, Jimmie Foxx, and Lefty Grove. The team left Philadelphia for Kansas City, Missouri, in 1955 and became the Kansas City Athletics before moving to Oakland, California, in 1968 and becoming the Oakland Athletics. The Athletics played their home games at the Oakland Coliseum from 1968 until 2024. Nicknamed the "Swingin' A's", under owner Charlie O. Finley they won three consecutive World Series in 1972, 1973, and 1974, led by players including Vida Blue, Catfish Hunter, Reggie Jackson, and Rollie Fingers. After being sold by Finley to Walter A. Haas Jr., the team won three consecutive pennants and the 1989 World Series behind the "Bash Brothers", Jose Canseco and Mark McGwire, as well as Hall of Famers Dennis Eckersley and Rickey Henderson and manager Tony La Russa. In 2002, the Athletics set an American League record for most consecutive wins in a season with twenty, marking the pioneering application of sabermetrics in baseball.
From 1901 through the end of 2025, the franchise's overall win–loss record is 9,405–9,945–87 (.486), and a 76–86 (.469) record since moving to West Sacramento in 2025.

History
The history of the Athletics Major League Baseball franchise spans from 1901 to the present day, having begun in Philadelphia before moving to Kansas City in 1955, Oakland, California, in 1968, and finally Sacramento, California, in 2025. The A's made their Bay Area debut on April 17, 1968, with a 4–1 loss to the Baltimore Orioles at the Coliseum, in front of an opening-night crowd of 50,164. With four locations, the A's have had the most home cities of any MLB team.
Team name and "A" logo
The Athletics' name originated in the term "Athletic Club" for local gentlemen's clubs—dates to 1860 when an amateur baseball team, the Athletic (Club) of Philadelphia, was formed. The team later turned professional in 1875, becoming a charter member of the National League in 1876, but were expelled from the N.L. after one season. A later version of the Athletics played in the American Association from 1882 to 1891.
Elephant mascot
After New York Giants manager John McGraw told reporters that Philadelphia manufacturer Benjamin Shibe, who owned the controlling interest in the new team, had a "white elephant on his hands", team manager Connie Mack defiantly adopted the white elephant as the team mascot, and presented McGraw with a stuffed toy elephant at the start of the 1905 World Series. McGraw and Mack had known each other for years, and McGraw accepted it graciously. By 1909, the A's were wearing an elephant logo on their sweaters, and in 1918 it turned up on the regular uniform jersey for the first time.
In 1963, when the A's were located in Kansas City, then-owner Charlie Finley changed the team mascot from an elephant to a mule, the state animal of Missouri. This is rumored to have been done by Finley in order to appeal to fans from the region who were predominantly Democrats at the time. (Traditionally, the symbol for the Republican Party is an elephant, while the Democratic Party's symbol is a donkey.) From 1988, the Athletics' 21st season in Oakland, through their final season in Oakland in 2024, an illustration of an elephant adorned the left sleeve of the A's home and road uniforms. Ahead of the team's first season in Sacramento, the elephant patch was removed and replaced with one depicting Sacramento's Tower Bridge.
Beginning in the mid-1980s, the on-field costumed incarnation of the A's elephant mascot went by the name Harry Elephante, a play on the name of singer Harry Belafonte. In 1997, he became Stomper, debuting Opening Night on April 2.
Uniforms
Over the seasons, the Athletics' uniforms have paid homage to their amateur forebears. Until 1954, when the uniforms had "Athletics" spelled out in script across the front, the team's name never appeared on either home or road uniforms. Furthermore, neither "Philadelphia" nor the letter "P" appeared on the uniform or cap. The Philadelphia uniform had only a script "A" on the left front, and likewise the cap usually had the same "A" on it. In the early days of the American League, the standings listed the club as "Athletic" rather than "Philadelphia", in keeping with the old tradition. Eventually, the city name came to be used for the team, as with the other major league clubs.
After buying the team in 1960, owner Charles O. Finley introduced road uniforms with "Kansas City" printed on them, with an interlocking "KC" on the cap. Upon moving to Oakland, the "A" cap emblem was restored, and in 1970 an "apostrophe-s" was added to the cap and uniform emblem to reflect that Finley was officially changing the team's name to the "A's".
While in Kansas City, Finley changed the team's colors from their traditional red, white and blue to kelly green and gold. It was here that he began experimenting with dramatic uniforms to match these bright colors, such as gold sleeveless tops with green undershirts and gold pants. The uniform innovations increased after the team's move to Oakland, which came with the introduction of polyester pullover uniforms.
During their dynasty years in the 1970s, the A's had dozens of uniform combinations with jerseys and pants in all three team colors, and never wore the traditional gray on the road, instead wearing green or gold, which helped to contribute to their nickname of "The Swingin' A's". After the team's sale to the Haas family, the team changed its primary color to a more subdued forest green in 1982 and began a move back to more traditional uniforms.
The 2023 team wore home uniforms with "Athletics" spelled out in script writing and road uniforms with "Oakland" spelled out in script writing, with the cap logo consisting of the traditional "A" with "apostrophe-s". The home cap, which was also the team's road cap until 1992, is forest green with a gold bill and white lettering. This design was also the basis of their batting helmet, which is used both at home and on the road. The road cap, which initially debuted in 1993, is all-forest green. The first version had the white "A's" wordmark before it was changed to gold the following season. An all-forest green batting helmet was paired with this cap until 2008. In 2014, the "A's" wordmark returned to white but added gold trim.
Planned relocation to Las Vegas
Following the California Golden Seals' relocation to Cleveland in 1976, the Golden State Warriors' move across the bay to San Francisco in 2019, and the Oakland Raiders' move to the Las Vegas metropolitan area in 2020, the Athletics were left as the sole remaining major professional sports team in Oakland. However, on April 20, 2023, the Athletics announced they had entered a land purchase agreement with Red Rock Resort located near Las Vegas to build a new ballpark on the Las Vegas Strip, finalizing their plans to relocate to the Las Vegas area. On May 9, 2023, the Athletics switched their planned location in the Las Vegas area to the site of the Tropicana Las Vegas hotel and casino, which permanently closed on April 2, 2024 and was subsequently demolished on October 9, 2024, to construct a 33,000-seat partially retractable ballpark and a 1,500-room hotel and casino. By June 15, 2023, Nevada governor Joe Lombardo signed an MLB stadium funding bill known as SB1 into law after the bill was approved by the Nevada Legislature, and the Athletics officially announced they would begin the relocation process.
On November 16, 2023, the Athletics' move to Las Vegas was unanimously approved by MLB team owners. According to the team, the new Las Vegas ballpark will not be completed until 2028. The lease to the Oakland Coliseum expired after the 2024 season. Before the scheduled move to Las Vegas in 2028, the team is playing in West Sacramento, California, at Sutter Health Park (home of the San Francisco Giants' Triple-A affiliate, the Sacramento River Cats) for the 2025–2027 seasons (with an option for the 2028 season if necessary). While in West Sacramento the team is referred to as simply the "A's" and "Athletics," with no city name attached. The relocation marks the first move by an MLB team since the Montreal Expos moved to Washington, D.C., becoming the Washington Nationals in 2005.
The Athletics are scheduled to play in Las Vegas for the first time in 2026, with six games scheduled in June at Las Vegas Ballpark. The new Las Vegas Stadium, currently unnamed, is on track to open by 2028.
On January 6, 2026, the Associated Press reported that the U.S. Patent and Trademark Office had denied the A's request to trademark the names "Las Vegas Athletics" and "Vegas Athletics", leaving the future of the franchise's name in doubt.
Rivalries
San Francisco Giants
The Bay Bridge Series was the name of a series of games played between the A's and San Francisco Giants of the National League. The series took its name from the San Francisco–Oakland Bay Bridge which links the cities of Oakland and San Francisco. Although competitive, the regional rivalry between the A's and Giants was considered by some a friendly one with mutual companionship between the fans, as opposed to White Sox–Cubs, or Yankees–Mets games where animosity runs high. Hats displaying both teams on the cap were sold from vendors at the games, and once in a while the teams would both dress in original team uniforms from the early era of baseball.
The series was also sometimes referred to as the "BART Series" for the Bay Area Rapid Transit system that links Oakland and San Francisco. However, the name was never popular beyond a small selection of history books and national broadcasters and had fallen out of favor. Bay Area locals almost exclusively referred to the rivalry as the "Battle of the Bay".
Originally, the term described a series of exhibition games played between the two clubs after the conclusion of spring training and immediately prior to the start of the regular season. It was first used to refer to the 1989 World Series in which the Athletics won their most recent championship and the first time the teams had met since they moved to the San Francisco Bay Area (and the first time they had met since the A's also defeated the Giants in the 1913 World Series). Later it referred to games played between the teams during the regular season from the commencement of interleague play in 1997 through the 2024 regular season. At the conclusion of the rivalry, due to the Athletics relocating out of the Bay Area, the Athletics had won 76 games and the Giants had won 72 contests.
The A's also had the edge on the Giants in terms of overall postseason appearances (21–13), division titles (17–10) and World Series titles (4–3) since both teams had moved to the Bay Area, even though the Giants franchise moved there a decade earlier than the A's did.
On March 24, 2018, the Oakland A's announced that for the Sunday, March 25, 2018, exhibition game against the San Francisco Giants, A's fans would be charged $30 for parking and Giants fans would be charged $50. However, the A's stated that Giants fans could receive $20 off if they shout "Go A's" at the parking gates.
Los Angeles Angels
The A's have held a rivalry with the Los Angeles Angels since their relocation to California in 1968, and the charter membership of both teams in the AL West in 1969. The A's and Angels have often competed for the division title. The peak of the rivalry was during the early part of the millennium as both teams were perennial contenders. During the 2002 season, the A's famous "Moneyball" tactics led them to a league record 20-game winning streak, knocking the Angels out of the first seed in the division. The A's finished 4 games ahead while the Angels secured the Wild Card berth. Despite the 103-win season for Oakland, they lost to the underdog Minnesota Twins in the ALDS. The Angels beat the heavily favored New York Yankees, then beat the Twins, and then won the 2002 World Series. During the 2004 season, the teams were tied for wins headed into the final week of September with the last three games being played in Oakland against the Angels. Both teams were battling to secure the division championship. Oakland lost two of the three games to the Angels, and they were eliminated from the playoff hunt. The Angels were swept in the playoffs by the eventual champion Boston Red Sox. The Athletics lead the series 541–491, and the two teams have yet to meet in the postseason.
Philadelphia Phillies (historic)
The City Series was the name of baseball games played between the Philadelphia Athletics and the Philadelphia Phillies of the National League, that ran from 1903 through 1955. After the A's move to Kansas City in 1955, the City Series rivalry came to an end. Since the introduction of interleague play in 1997, the teams have since faced each other during the regular season (with the first games taking place in 2003) but the rivalry had effectively died in the intervening years since the A's left Philadelphia. In 2014, when the A's faced the Phillies in inter-league play at the Oakland Coliseum, the Athletics did not bother to mark the historical connection, going so far as to have a Connie Mack promotion the day before the series while the Texas Rangers were in Oakland.
The first City Series was held in 1883 between the Phillies and the American Association Philadelphia Athletics. When the Athletics first joined the American League, the two teams played each other in a spring and fall series. No City Series was held in 1901 and 1902 because of legal warring between the National League and American League.
Achievements
Awards
The Athletics give out an award named the Catfish Hunter Award since 2004 for the most inspirational Athletic.
Retired numbers
The Athletics have retired six numbers; additionally, Walter A. Haas, Jr., owner of the team from 1980 until his death in 1995, was honored by the retirement of the letter "A". Of the six players with retired numbers, five were retired for their play with the Athletics and one, 42, was universally retired by Major League Baseball when they honored the 50th anniversary of Jackie Robinson's breaking the color barrier. No A's player from the Philadelphia era has his number retired by the organization. Though Jackson and Hunter played small portions of their careers in Kansas City, no player that played the majority of his years in the Kansas City era has his number retired either. The A's have retired only the numbers of Hall-of-Famers who played large portions of their careers in Oakland. The Athletics have all of the numbers of the Hall-of-Fame players from the Philadelphia Athletics displayed at their stadium, as well as all of the years that the Philadelphia Athletics won World Championships (1910, 1911, 1913, 1929, and 1930). Dave Stewart was about to have his #34 jersey retired by the Athletics in 2020, but the ceremony was postponed until further notice, due to the COVID-19 pandemic. Questions were raised if there would be a formal ceremony after no news about a reschedule happened in 2021 before it was announced in April 2022 that Stewart would have his jersey retired on September 11, 2022. Stewart broke the A's tradition in that his number was a re-retirement, as well as his not being in the Hall of Fame.
Athletics Hall of Fame
On August 14, 2018, the team publicly announced the creation of a team Hall of Fame, complete with the first seven names to be inducted. On September 5, the Athletics held a ceremony to induct seven members into the inaugural class. Each member was honored with an unveiling of a painting in their likeness and a bright green jacket. Hunter, who died in 1999, was represented by his widow, while Finley, who died in 1996, was represented by his son. If the team ever gets a new stadium, a physical site will be designated for the Hall of Fame, as the Coliseum does not have enough space for a full-fledged exhibit. In August 2021, it was announced that players Sal Bando, Eric Chavez, Joe Rudi, director of player development Keith Lieppman, and clubhouse manager Steve "Vuc" Vucinich would be part of the class of 2022; in November 2021, Ray Fosse, who had died the previous month, was posthumously inducted into the Hall of Fame. The 2023 & 2024 classes were inducted in August of each respective year.
Bay Area Sports Hall of Fame
17 members of the Athletics organization have been honored with induction into the Bay Area Sports Hall of Fame.
Philadelphia Baseball Wall of Fame
The Athletics have all of the numbers of the Hall-of-Fame players from the Philadelphia Athletics displayed at their stadium, as well as all of the years that the Philadelphia Athletics won World Championships (1910, 1911, 1913, 1929, and 1930).
Also, from 1978 to 2003 (except 1983), the Philadelphia Phillies inducted one former Athletic (and one former Phillie) each year into the Philadelphia Baseball Wall of Fame at the then-existing Veterans Stadium. 25 Athletics have been honored. In March 2004, after Veterans Stadium was replaced by the new Citizens Bank Park, the Athletics' plaques were relocated to the Philadelphia Athletics Historical Society in Hatboro, Pennsylvania, and a single plaque listing all of the A's inductees was attached to a statue of Connie Mack that is located across the street from Citizens Bank Park.

Radio and television
As of the 2020 season, the Athletics have had 14 radio homes. The Athletics' flagship radio station is KSTE and the team has a free live 24/7 exclusive A's station branded as A's Cast to stream the radio broadcast within the Athletics market and other A's programming via iHeartRadio. Going into the 2020 season, the Athletics had a deal with TuneIn for A's Cast and no flagship radio station in the Bay Area; due to the COVID-19 pandemic keeping fans from attending games, the team changed their plans and named KNEW as flagship. The announcing team features Ken Korach and Johnny Doskow.
Television coverage is exclusively on NBC Sports California. Some A's games air on an alternate feed of NBCS, called NBCS Plus, if the main channel shows a Sacramento Kings or San Jose Sharks game at the same time. On TV, Jenny Cavnar covers play-by-play, and Dallas Braden provides color commentary. Some games would feature Chris Caray on play-by-play; Caray is a fourth-generation baseball announcer that included great-grandfather Harry Caray, grandfather Skip Caray, and father Chip Caray.
