1973 Topps #645 Bob Locker
About Bob Locker
Locker's 1973 Topps #645 is a high number from the fifth and final series, whose cards are in smaller supply, and it carries the Chicago Cubs. He had told Cubs general manager John Holland he would pitch only one season in Chicago, then wanted to be traded back to the A's, as owner Charlie Finley had agreed to try to arrange. Locker moved his family to Oakland, where he planned to live and work after his baseball career.
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.
