When you combine the club's stints in Philadelphia, Kansas City and Oakland, the list of legends who have donned an A's uniform becomes quite impressive.
We've compiled a list of the best player to wear each uniform number in A's history. Note: They aren't on this list, but don't forget about the Hall of Famers who played for the franchise before jersey numbers were used, such as Rube Waddell, Chief Bender and Frank "Home Run" Baker.
00: DH Don Baylor
Baylor remains the lone player in A's history to have donned the double zeros. The slugger wore the number for one season, which was also his final Major League season in 1988.
No. 1: SS Eddie Joost
San Francisco native donned the number from 1947-54 with the Philadelphia incarnation of the A's. The shortstop was an All-Star in '49 and '52.
No. 2: DH Khris Davis
Davis went on an elite power run from 2016-18 as the game's most prolific slugger with 133 homers, including a league-leading 48 in '18. He already ranks fifth on the A's all-time home run list with 158 big flies.
No. 3: 1B Jimmie Foxx
Foxx was the first player in franchise history to wear No. 3, and enjoyed a legendary Hall of Fame career. Eric Chavez gets an honorable mention here.
No. 4. SS Miguel Tejada
Pretty easy call here, with Tejada the 2002 AL MVP and a key piece of Oakland's talented clubs of the early 2000s. Carney Lansford and Sam Chapman also deserve some love here.

No. 5: 1B Dick Siebert
All-Star first baseman who batted .283 in eight seasons with the A's from 1938-45.
No. 6: 3B Sal Bando
A four-time All-Star and the heart of the A's dynasty that won three straight World Series titles from 1972-74, "Captain Sal" remains one of the most popular players in franchise history. Current A's manager Bob Melvin now wears the No. 6 in honor of Bando.
No. 7: OF Al Simmons
Simmons wore No. 6 during his second stint with the A's, but the Hall of Famer was in his prime wearing No. 7 from 1931-32.
No. 8: C Frankie Hayes
Hayes was a four-time All-Star and batted .270 over 11 seasons with the Philadelphia A's. Jed Lowrie gets an honorable mention here.

An all-time great and arguably the best pitcher in A's history.
No. 11: OF Tony Armas
Though his All-Star season with the A's came wearing No. 20 in 1981, Armas still was a productive player from '77-80 donning the No. 11. The outfielder mashed 35 home runs with 109 RBIs in '80.
No. 12: OF Matt Stairs
Stairs crushed 122 home runs over five seasons with the A's. His career-high 38 homers and 102 RBIs in 1999 even earned him AL MVP votes.
No. 13: RHP John Odom
Aside from having one of the coolest nicknames in baseball, Blue Moon was also an outstanding pitcher. A member of the A's dynasty that won three straight World Series titles from '72-74, Odom was a two-time All-Star in 12 seasons with the A's, going 80-76 with a 3.53 ERA.
No. 14: LHP Vida Blue
Blue was part of a dominant starting rotation that helped form a dynasty in the 1970s with three straight World Series titles from '72-74. In '71, he became one of just 11 pitchers who have won both the Cy Young and MVP Award in the same year.
No. 15: RHP Tim Hudson
Hudson was dominant over six seasons in Oakland, going 92-39 with a 3.30 ERA.
No. 16: 1B Jason Giambi

One of the best players not in the Hall of Fame, "Campy" remains the A's all-time hits leader (1,882) and was a five-time All-Star over 13 seasons with the club.

No. 24: LF Rickey Henderson
Not a whole lot of explaining necessary for this one. One of baseball's all-time greats, Henderson is the greatest player to don an A's uniform.
No. 25: 1B Mark McGwire
