Robert "Bo" Belinsky (December 7, 1936 – November 23, 2001) was an American left-handed pitcher in Major League Baseball. He became a California celebrity as a rookie with the original Los Angeles Angels. He is best known for pitching a no-hitter against his former Major League Baseball team, the Baltimore Orioles, in 1962. Belinsky is one of only two pitchers in the history of the Angels to start his career with a four-game winning streak or better. The other was Jered Weaver, in 2006.
