Born in Covington, Virginia, the,, Lemon was known as "Bob" before he signed with MLB. He signed originally with the Cleveland Indians but he never won a regular job with Cleveland; indeed, he was a "late-bloomer" who required several trips to the minor leagues before finally winning a regular berth with the 1956 Senators at the age of 28. A free-swinger who three times led the American League in striking out, Lemon and his teammates benefitted from new Washington owner Calvin Griffith's decision to move the left field fences closer to home plate in the Senators' cavernous ballpark, Griffith Stadium. Lemon smashed 27 homers in 1956, also leading the league in triples, then followed with 26, 33 and 38. He twice compiled over 100 runs batted in and became a favorite of U.S. President Dwight Eisenhower after Eisenhower attended Lemon's 3-home-run performance at Griffith Stadium in 1956. However, the home run exploits of Lemon and his teammates were more than offset by poor pitching, and after multiple second-division finishes in the AL, Griffith moved the Senators to Minneapolis–St. Paul after the 1960 campaign to become the Minnesota Twins. But Lemon left his stroke behind in Washington, and after only 14 homers in Minnesota in 1961 and an injury-ruined 1962, his career wound down quickly. His last year as a player, 1963, was divided among the Twins, Philadelphia Phillies and Chicago White Sox. All told, he appeared in 1,010 games over all or parts of 12 major league seasons and batted.262 with 164 home runs.
Coach and manager
Lemon remained in the game as a coach for the Twins, serving two different terms in that role, including with the 1965 pennant-winning team. In between, in 1968, he returned to Washington as manager of the expansion Senators, but his popularity as a player did not translate to a successful managerial record. His club finished last in the ten-team American League, winning 65 games and losing 96 —but it did feature a fearsome, right-handed power-hitter in Frank Howard. Lemon was fired after only one season. As a native son, and to honor his batting achievements with the original Senators, he was elected to the Virginia Sports Hall of Fame in 1988. Jim Lemon died from cancer at the age of 78 at his Brandon, Mississippi home.
