2. Bruce Sutter: 133 saves
Although Hall of Famer Bruce Sutter won a World Series with the St. Louis Cardinals in 1982, he was just as dominant when he pitched in a Cubs uniform. In fact, Sutter was a Cub when he became one of the few relief pitchers ever to win the National League Cy Young award, which he secured in 1979. In 62 games that year, Sutter led the league with 37 saves with a 2.22 ERA and 110 strikeouts in 101.1 innings pitched.
Another mind-boggling Bruce Sutter stat is the fact that he posted an ERA+ of 328 (league average is 100) in the 1979 season. Sutter was one of the most dominant relievers of his era and he made four All-Star teams with the Cubs during his five years with the team.
