Mace Brown

One of the first relief specialists, Brown set a record in 1938 by becoming the first pitcher to twice make 50 appearances in a season without recording a complete game. He led Pittsburgh in wins (15, all in relief) in 1938, in a major league-high 51 appearances, but surrendered the “Homer in the Gloamin'” to Gabby Hartnett that propelled Chicago past Pittsburgh and on to the NL pennant. Brown again led the AL with 49 games in 1943. He is credited with 48 career saves.
