Pitcher Jumbo Brown was, according to most sources, the heaviest player ever to play major league baseball*. A reliever, he didn't become a closer until the last four years of his career. He never stole a base in his major league career, but he did hit a triple once as a young player.
When he broke into major league ball, he was the youngest player in the National League.
- The "heaviest player" no longer applies as Jonathan Broxton has been listed at 300 pounds.
