David Anthony Fleming (born November 7, 1969) is a former Major League Baseball pitcher who played from 1991 to 1995, mostly for the Seattle Mariners.
Fleming was born in Jackson Heights, Queens, New York, and went to high school in Mahopac, New York. He pitched for the University of Georgia, leading them to a College World Series title in 1990.
Fleming was selected in the third round of the 1990 Major League Baseball Draft by the Seattle Mariners. He won a career high 17 games, including 9 in a row, for the Mariners in his rookie season of 1992. His ERA that year was 3.39, and he took third place in the AL Rookie of the Year voting (behind winner Pat Listach).
After going 29-15 in his first two MLB seasons, Fleming began to struggle with arm trouble. On 7 July 1995, he was traded by the Mariners to the Kansas City Royals for Bob Milacki. He pitched only 9 games for the Royals before undergoing surgery, and never pitched in the Major Leagues again.
