Oakland Athletics

Oakland American League West

The Athletics are baseball’s most restless original — a 1901 American League charter club that has already packed three cities and is staring at a fourth. Nine World Series titles, Connie Mack’s half-century on the bench, Charlie Finley’s mustaches, and Billy Beane’s spreadsheets give the franchise a history too large for any one skyline.

From the “$100,000 infield” in Philadelphia to the Mustache Gang’s Oakland three-peat, from the Earthquake Series to Moneyball to a last Coliseum night in 2024, the A’s have been a dynasty factory that keeps selling stars and reinventing itself. Green and gold travel. The argument about where they belong never does.

Philadelphia Athletics debut

Connie Mack’s American League original plays its first game — tailcoat, scorecard, and a franchise that will outlive three cities. Trace the founding story in the Team Origin quiz.

Origins

The franchise began in 1901 as a founding American League club in Philadelphia, managed — and later owned — by Connie Mack for fifty seasons. Mack’s first dynasty won the World Series in 1910, 1911, and 1913 with the so-called $100,000 infield. His second, built around Lefty Grove, Jimmie Foxx, Al Simmons, and Mickey Cochrane, won in 1929 and 1930 and returned in 1931. Financial reality repeatedly forced Mack to sell stars; by the 1950s the Philadelphia A’s were a last-place tenant. The founding story lives in the Team Origin quiz; Grove’s peak is the Lefty Grove quiz.

The club moved to Kansas City in 1955 and spent 13 mostly losing seasons as a development hub often linked to the Yankees. Owner Charlie Finley then took the franchise to Oakland in 1968 — green and gold, a mule named Charlie O, and a Coliseum that would become one of baseball’s strangest fortresses. From Mack’s tailcoats to Finley’s orange baseball ideas, the origin story is an American League original that never stayed put.

Oakland immediately produced a dynasty. The Mustache Gang of 1972, 1973, and 1974Reggie Jackson, Catfish Hunter, Rollie Fingers, Vida Blue, Sal Bando, Bert Campaneris — won three straight World Series, the only club besides the Yankees to three-peat in the divisional era. Relive that run in the 1972–74 Athletics quiz, the Reggie Jackson quiz, and the Rollie Fingers quiz.

History

After Finley’s colorful, combative 1970s, the club dipped and then rebuilt under Tony La Russa. The late-1980s A’s — Bash Brothers José Canseco and Mark McGwire, Dave Stewart, Dennis Eckersley, and a returned Rickey Henderson — won the 1989 World Series against the Giants, a Bay Area series interrupted by the Loma Prieta earthquake. They had lost to Kirk Gibson’s Dodgers in 1988 and would be swept by the Reds in 1990. The Earthquake Series lives in the 1989 Athletics quiz; Eckersley’s closer transformation is the Dennis Eckersley quiz; Rickey’s stolen-base empire is the Rickey Henderson quiz.

The 2000s Moneyball A’s, immortalized in Michael Lewis’s book, used undervalued on-base skills to reach October on a budget. Billy Beane’s operation never won a pennant in that era, but it changed how front offices everywhere built rosters. Later Oakland clubs — the 2012–14 contenders, the 2018–20 groups with Matt Chapman and Marcus Semien — kept punching above payroll. The Coliseum, with its vast foul territory and Mount Davis, was a quirky fortress until the lease ran out.

Mark Kotsay’s 2023 club won 50, lost 112, and finished last — Brent Rooker the 30-homer bat, Esteury Ruiz the stolen-base champion, a teardown in public. The 2024 team won 69, finished fourth, and closed the Coliseum: Rooker hit 39, JP Sears won 11, and 57 Oakland seasons ended. The 2025 Athletics won 76 in West Sacramento — Nick Kurtz the Rookie of the Year, Jacob Wilson hitting .311 — a first season with no city on the jersey while Las Vegas waits.

Championships

The Athletics have won nine World Series championships and fifteen American League pennants — a ledger split across Philadelphia and Oakland, with Kansas City contributing none.

  • 1910 — Athletics 4, Chicago Cubs 1 (Mack’s first dynasty; $100,000 infield)
  • 1911 — Athletics 4, New York Giants 2
  • 1913 — Athletics 4, New York Giants 1
  • 1929 — Athletics 4, Chicago Cubs 1 (Grove, Foxx, Simmons, Cochrane)
  • 1930 — Athletics 4, St. Louis Cardinals 2
  • 1972 — Athletics 4, Cincinnati Reds 3 (first of the Oakland three-peat)
  • 1973 — Athletics 4, New York Mets 3
  • 1974 — Athletics 4, Los Angeles Dodgers 1 (three straight; only non-Yankees divisional-era three-peat)
  • 1989 — Athletics 4, San Francisco Giants 0 (Earthquake Series; La Russa, Stewart, Eckersley)

Near-misses stack high: the 1905 and 1914 losses, the 1931 rematch with St. Louis, Gibson’s 1988 Dodgers, and the 1990 Reds sweep. The Oakland three-peat is in the 1972–74 Athletics quiz; the last title is the 1989 Athletics quiz.

Oddities

A’s lore is tailcoats, mustaches, a mule, a book that changed the sport, and a franchise that will not stay on one map.

  • Mack for fifty: Connie Mack managed the club from 1901 through 1950 — suit, scorecard, and two separate dynasties. No one else has a half-century in one dugout. See the Team Origin quiz.
  • $100,000 infield: Home Run Baker, Eddie Collins, Jack Barry, and Stuffy McInnis were marketed as a luxury infield — then Mack sold them when the books demanded it.
  • Three cities, a fourth coming: Philadelphia to Kansas City (1955) to Oakland (1968) to Sacramento (2025) while Las Vegas is built. The uniforms dropped the city name in the interim.
  • Finley’s circus: Charlie O the mule, mustache bonuses, white shoes, and ideas for orange baseballs. The 1970s A’s looked like no other club — and won three straight. Covered in the 1972–74 Athletics quiz.
  • Rickey being Rickey: The stolen-base king spoke in the third person, referred to himself as the greatest of all time, and was usually right. The Rickey Henderson quiz is the roll call.
  • Earthquake Series: Game 3 of the 1989 World Series was delayed ten days after the Loma Prieta quake. When it resumed, Oakland swept the Giants. Relive it in the 1989 Athletics quiz.
  • Moneyball: Beane’s on-base gospel, a 20-game win streak in 2002, and a book that became a movie — a pennant never arrived, but every front office copied the homework.
  • The last night in Oakland: After 57 seasons, 2024 was the final Coliseum year — 69 wins, Rooker’s 39 homers, and a goodbye that felt like an eviction. See the 2024 Athletics quiz.
  • Sacramento first: 2025 at Sutter Health Park, Nick Kurtz the Rookie of the Year, no city on the jersey. Covered in the 2025 Athletics quiz.

The roster of memory

Notable Players

Legends, franchise faces, and the names every Oakland Athletics fan should know.

Reggie Jackson

OF 1967–1975, 1987 Hall of Fame

Mr. October

Hall of Fame slugger whose Oakland years — the 1973 MVP, the Mustache Gang three-peat, and the swing that made October a nickname — remain the franchise’s loudest offensive chapter. Jackson left, became a Yankee legend, and still came home to finish in green and gold. Dig deeper in the Reggie Jackson quiz.

Rickey Henderson

LF 1979–1984, 1989–1995, 1998 Hall of Fame

Stolen-base king

The greatest leadoff hitter who ever lived — stolen bases, walks, and a third-person commentary track. Rickey’s Oakland chapters include the 1980s breakout and the 1989 title return. He is still the all-time stolen-base leader, and he is still talking about it. See the Rickey Henderson quiz.

Lefty Grove

P 1925–1933 Hall of Fame

Mack’s ace

Hall of Fame left-hander whose Philadelphia peak — strikeouts, ERA titles, and the 1929–31 pennants — made Connie Mack’s second dynasty possible. Grove was mean on the mound and unmatched in his era. Relive it in the Lefty Grove quiz.

Rollie Fingers

P 1968–1976 Hall of Fame

Handlebar closer

Hall of Fame reliever whose mustache and slider closed the 1972–74 three-peat — the visual of Finley’s A’s as much as the save. Fingers turned the ninth inning into a named job. Covered in the Rollie Fingers quiz and the 1972–74 Athletics quiz.

Dennis Eckersley

P 1987–1995 Hall of Fame

Closer reinvented

Hall of Famer who arrived as a starter and left as the prototype closer — the 1988–92 peak, the 1992 MVP and Cy Young, and the 1989 title. One Gibson swing in 1988 is the scar; everything else is the standard. See the Dennis Eckersley quiz.

Catfish Hunter

P 1965–1974 Hall of Fame

Finley’s ace

Hall of Fame right-hander whose control and October work anchored the Mustache Gang. Hunter’s 1974 Cy Young was the last Oakland chapter before free agency took him to New York — and changed how players got paid. Covered with the three-peat in the 1972–74 Athletics quiz.

Jimmie Foxx

1B 1925–1935 Hall of Fame

Double X

Hall of Fame first baseman whose Philadelphia power — MVPs, 50-homer thunder, and the 1929–31 pennants — made Mack’s second dynasty a slugger’s show. Foxx was the right-handed Babe for a generation of A’s fans. His era sits next to Grove in the Lefty Grove quiz and the Team Origin quiz.

Vida Blue

P 1969–1977

1971 MVP and Cy Young

Left-hander whose 1971 MVP-and-Cy-Young season announced the Oakland dynasty before it had a ring. Blue’s fastball and the three titles that followed are the pitching half of Finley’s circus. Relive them in the 1972–74 Athletics quiz.
