Rube Waddell, LHP
Career: 1897-1910, Pirates, A's, Browns
Fun fact: Held K's record by LHP (349)
The top power pitcher of his day, Waddell won six strikeout titles with plus stuff: plus heat, big-bending curve and a screwball. He was a bit of a screwball too, frustrating teams, chasing passing fire engines, drinking heavily and losing focus easily.
Waddell was eccentric on the field, having his outfielders sit down before striking out the side.
