Dinneen won 20 games for the 1900 Braves but really came into his own when he jumped to the Red Sox in 1902. He had three straight seasons of 21 or more wins. The hero of the 1903 WS, he won three of four decisions. Two of his victories, including the final game, were shutouts. In 1905, he pitched a no-hitter against the White Sox. Dineen went directly from pitching in the AL to umpiring in the league. During his 29 years as an AL umpire, he worked in 45 WS games. During the early 1930s, the AL gave a cash prize to the umpire with the lowest average time for his games. The winner was Dineen.
