Who is the greatest left-handed pitcher of all-time?
How important are awards and All-Star appearances? In the battle for the best left-handed starter, it makes a big difference. With awards and All-Stars included, Randy Johnson comes out on top with a score of 270.10, followed by Steve Carlton (#2, 267.64) and Warren Spahn (#3, 244.40). When awards and All-Stars are removed from the equation, Spahn narrowly beats Carlton for the top spot and the Big Unit drops to third place. I know Johnson was intimidating, but there is no way I would pick him over either Spahn or Carlton when building my historical fantasy team. Sandy Koufax (#8, 180.58) would be another consideration, but he has a lower score due to his short career; in twelve years he won 165 games and compiled a WAR of 50.3.
Only two other lefties topped the 200-point mark: Lefty Grove (#4, 203.46) and Eddie Plank (#5, 200.01). Tom Glavine (#6, 198.62) just barely missed. Overshadowed by Greg Maddux during his prime, Glavine is perhaps the best number two starter in history. His baseball cards are a dime a dozen; even his rookie cards can many times be had for less than a dollar.
Carl Hubbell is next on the list with a score of 185.94, and two non-Hall of Famers, Tommy John (#9, 176.01) and Jim Kaat (#10, 170.14), round out the top ten. Both were very close to the 300-win mark, but had very long careers in which they amassed all those wins and only averaged 13 victories per season.
