1971 Topps #356 Bob Locker
About Bob Locker
Locker spent 1971 as a full-season Athletic, going 7-2 with a 2.86 ERA and 6 saves. He pitched 72 1/3 innings in 47 games for an Oakland club that won 101 games. Manager Dick Williams used him as a rally-killer. He pitched two-thirds of an inning in the ALCS, which Baltimore swept 3-0. Card #356, from the third series, pictures him with the Athletics.
Bob Locker was a right-handed relief pitcher from George, Iowa, who built his career on a sinker he could throw with full fastball velocity. A geology graduate of Iowa State, he lost two seasons to military service before reaching the majors at age 27 in 1965. He pitched for the Chicago White Sox, Seattle Pilots, Milwaukee Brewers, Oakland Athletics and Chicago Cubs. In Chicago he worked in a bullpen that led the league in ERA for four straight years, and in Oakland he was part of the team that won the 1972 World Series. He finished with a 2.75 career ERA and 95 saves over 576 games, all in relief.
