Yeah, but is that good for Sabathia, or good for Beckett?
Sabathia started four more games and still has fewer wins. Of course wins aren't everything, but with four more starts and forty more innings, Sabathia's other numbers should be considerably better in order to beat out Beckett. Frankly, they're not.
With a little more luck, Sabathia could be 24-5 right now. He's had six starts this season where he gave up two runs or fewer in 7+ innings and took a loss or no-decision, including four straight just last month. Beckett has only had three such starts. It's not his fault that he gets poorer run support than Beckett.
