30. Rube Waddell
As one of baseball’s original players, Rube Waddell quickly became among the first hard-throwing strikeout pitchers, a spectacle that fans eagerly watched. When his career came to a close, he had 2,316 strikeouts under his belt – especially astonishing in an era where hitters were more focused on putting the ball in play. Even more astonishing is the fact that his strikeout-to-walk ratio was 3 to 1.
