Howie Krist
Howard Wilbur Krist was a pitcher in Major League Baseball from 1937 to 1946. "Spud" played his entire career for the St. Louis Cardinals of the National League, and was a member of the 1942 and 1946 World Series Championship teams.
Krist's 10–0 record in 1941, his first full season, is the third-best undefeated season ever. He served in the army for two years in Europe during World War II, and lost his effectiveness as a pitcher due to a injury sustained while leaping into a foxhole.
