Gallego was the Athletics' starting second baseman during their three-year run of AL championships from 1988 through 1990, which included a World Series sweep in 1989 against their Bay Area rivals, the San Francisco Giants. Throughout his career, he was known more for his glove than his bat. In 1990, he led the AL in sacrifice hits with 17. He had 28 hits without an extra-base hit in 1995, still the post-1912 non-pitcher record. Gallego's 12 home runs in 1991 set a career high.
While playing with the Yankees from 1992 to 1994, Gallego was the last player to wear the uniform number 2 prior to the Yankees' Hall of Fame shortstop, Derek Jeter.[2] Upon his return to the Oakland A's in 1987, Gallego refused to give up uniform number 9 that Reggie Jackson had worn previously with the A's, forcing Jackson to wear number 44 for his final season.[3]
Gallego closed out his career with the Cardinals in 1996 and 1997, where he once again played under Tony La Russa, his manager while with the A's.
