A highly competitive control pitcher who told teammates, "If you don't hustle when I'm pitching, I'll kick your ass," Bosman was 14-9 with an American League-best 2.19 ERA for the Senators in 1969. He won a career-high 16 in 1970, and on July 19, 1974, no-hit the Oakland Athletics while with the Cleveland Indians, losing a perfect game on his own throwing error. Bosman won 11 to help Oakland to a division title in 1975, but the A's cut him in 1977. He made his only postseason appearance with the A's against the Boston Red Sox in the 1975 ALCS; he pitched a third of an inning in relief.
Bosman was the pitching coach for the Chicago White Sox (1986-1987), Baltimore Orioles (1992-1994) and Texas Rangers (1995-2000). He was a pitching instructor in the Orioles chain from 1988 to 1991, and he has been a coach in the Tampa Bay Devil Rays' system from 2002 to 2011.
