Jackie Spencer Moore (born February 19, 1939) is an American former professional baseball catcher, coach and manager. He spent all or parts of 12 years over five separate terms as a Texas Rangers coach, and 32 years in all as a coach for eight different Major League Baseball (MLB) teams. Moore managed the Oakland Athletics (1984–86), and played part of one season with the Detroit Tigers as a third-string catcher in . Playing career After graduating from Bellaire High School in Houston, Texas, Moore joined the Tigers as an amateur free agent in when just eighteen years old. He started his minor-league career as an outfielder, with the Montgomery Rebels in 1957, but was converted to catcher in and remained behind the plate the rest of his playing career. He hit .264, with 43 home runs and 162 runs batted in, in the eight years in the Tigers' farm system before being called up to the parent club for the 1965 season only. He caught 12 innings of a 13-inning marathon against the California Angels in his Major League debut, and his first MLB hit was a thirteenth-inning single that moved the eventual winning run to third. But after that, he didn't get much playing time behind perennial All-Star Bill Freehan and backup catcher John Sullivan. His MLB career consisted of just 53 at-bats with a meager .094 batting average. On October 4, , the Tigers acquired starting pitcher Bill Monbouquette from the Boston Red Sox for George Smith, George Thomas and a player to be named later, which turned out to be Moore just nine days later. He spent 1967 in the BoSox organization as a catcher for the Triple-A Toronto Maple Leafs of the International League before retiring as an active player.

In two seasons under Moore, Jamestown went 64–85.
