Combining power, speed, and an exceptional arm, Lemon joined the Indians in 1950 but lost 1951 and 1952 to the Korean War. Sold to the Senators in May 1954, in 1956 he hit 27 home runs and led the AL in triples and in double plays by an outfielder. That August 31 he became the first Senator to hit three consecutive home runs. Lemon led the AL in strikeouts three years in a row (1956-58); his 138 strikeouts in 1956 (in a 154-game season) set a record. On September 5, 1959 he tied two ML records by hitting two homers and driving in six runs in one inning. He had 100 RBI in both 1959 and 1960. In 1960 he chased Mickey Mantle and Roger Maris for the AL home run crown, losing to Mantle 40 to 38. Slowed by injuries in 1961 and 1962, he attempted a comeback as a first baseman with the Phillies in 1963. He coached for the Twins from 1965 to 1967 and managed the Senators to their usual last-place finish in 1968. Replaced by Ted Williams for 1969, he remained in baseball as a batting coach, mainly with the Twins.
