16. Sam Leever

Sam Leever played the entirety of his career with the Pittsburgh Pirates, a team he first joined in 1898.

After playing five Games in 1898, at age 27, Leever had a good rookie year in 1899, leading the NL in Games Pitched (51) and Innings Pitched (379), though he had a losing record (21-23) and had a 3.18 ERA.  Leever never had a season where he pitched over 300 Innings again, and he was far more effective, never having an ERA over three and winning the ERA Title in 1903.  He had four 20-Win seasons, winning 194 Games against only 100 Losses, an excellent record even if you don’t hold a Pitcher’s winning percentage in high regard.

Although he did not pitch in the Series, he was a member of the Pirates team that won it all in 1908, their first championship.  Leever retired after the 1910 season with 847 Strikeouts and a 2.47 ERA and is one of the most forgotten stars in Pirates history.
