Davis, who played for five teams in his 19 seasons, started his career with the San Francisco Giants in 1981 and spent his first seven years with the team, making the All-Star team twice.
The native of Kingston, Jamaica, worked as a hitting coach for Triple-A Pawtucket, the Boston Red Sox' affiliate, last season. Davis was a hitting coach in the Los Angeles Dodgers' chain in 2010 and has also served as the hitting coach for the Australian National Team. He is the first player born in Jamaica to appear in a major league game.
In addition to his time with the Giants, Davis spent seven years with the then-California Angels in two stints with the team. He finished his playing career with the New York Yankees in 1998 and 1999, helping the team win two of its three straight World Series championships.
The switch-hitter batted .274 with 350 home runs and 2,380 hits in 2,436 career games. He also made the All-Star team with the Angels in 1994 and won a World Series title with the Minnesota Twins in 1991. He replaces Gerald Perry on the A's staff.
Davis is one of several A's coaches who played baseball in the Bay Area during the 1980s. Manager Bob Melvin played for the Giants from 1986 through 1988 and he competed as an amateur for Cal. He is a native of the South Bay.
Pitching coach Curt Young and third base coach Mike Gallego were longtime members of the Oakland A's during the 1980s. New bench coach Chip Hale is a native of Moraga, California, and played his high school baseball in the 1980s at Campolindo before embarking on a career that took him to the major leagues. And bullpen coach Rick Rodriguez was the A's second round pick in 1981 and he was on the A's briefly as a pitcher in 1986 and 1987. He is a native of the East Bay, as well.
First base coach Tye Waller's connections to the Bay Area are less significant. He grew up in central California (Fresno) and was drafted by the Giants in 1975, but didn't sign with San Francisco. He would make his major league debut with the St. Louis Cardinals.
