Robert Andrew Dustal (September 28, 1935 – November 30, 2015) was an American professional baseball player. A 6 ft (1.8 m), 172 lb (78 kg) right-handed pitcher whose professional career lasted for 14 seasons (1955–1968), Dustal appeared in seven Major League games as a relief pitcher for the 1963 Detroit Tigers. In his only decision, on April 20, 1963, at Fenway Park, he suffered an excruciating loss when he allowed a game-winning, two-run double to Román Mejías in the bottom of the 15th inning to give the Boston Red Sox a come-from-behind, 4–3 victory over his Tigers.
