James Gorman Thomas III (born December 12, 1950) is an American former professional baseball player. He played Major League Baseball (MLB) as a center fielder and right-handed hitter. Thomas played in the American League (AL) with the Milwaukee Brewers (1973–76, 1978–83, 1986), Cleveland Indians (1983) and Seattle Mariners (1984–86). With the Brewers, Thomas was one of the franchise's most popular players. He was a leading home run hitter in the late 1970s and early 1980s, though he hit for a low batting average and frequently struck out. Thomas had good fielding skills and his throwing arm was strong until shoulder surgery in 1984, after which he became a designated hitter until his retirement in 1986.
