According to PECOTA, Baseball Prospectus’ prediction system, Stephen Strasburg will have the lowest ERA of any starting pitcher in the league. He isn’t the most valuable starter because they only have him starting 23 games, not the 31-33 that a full season would bring. So because of limited playing time, he ranks behind Verlander, Halladay, Sabathia, Lincecum and Lee with WARP, but with ERA, he’s the leader.
Here are the predictions for starting pitchers in the league
As you can see, Saint Stephen leads the pack of pretty impressive guys. And if you’re wondering how he stacks up against AL pitchers, he’s a half a run ahead of his closest competition. What does this all mean? Is he really the unequivocally best pitcher in baseball right now?
