Sizemore got off to a slow start in . He was batting .257 with one home run, twelve RBIs and fourteen runs scored when he ruptured his thigh muscle on June 11 against the St. Louis Cardinals. He returned in late July, and his hitting actually improved. He batted .342 to bring his season average to .306 until a sprained wrist ended his season. That winter, he and minor league catcher Bob Stinson were traded to the Cardinals for slugging first baseman Dick Allen.
