~Jumbo Brown 1907–1966 (Cubs 1925)
When Brown came up with the Cubs as a rookie, he immediately set a record. He was the heaviest player to ever play in the big leagues at that time; tipping the scales at 295 pounds. He may be remembered for his size, but Jumbo was actually a trailblazer in the big leagues. He was one of the first pitchers who was kept on a roster strictly as a relief pitcher. In the first three and last four seasons of his big league career, he didn’t start a single game.
