Comments Off on An Upgrade UPDATED
On the surface, the McCarthy for Nuno swap between Arizona and the Yankees looks like little more than a shuffling of the deck chairs on the Titanic. But, beneath the surface, the Yankees have made themselves a bit better.
You our have to look beyond ERA to evaluate this deal and become comfortable with the notion that pitchers have no control over what happens to balls hit in the field of play. They could have a good defense behind them that gets to everything, or they could have a terrible defense behind them that let’s everything drop in. In either instance, their ERA would be greatly impacted. That’s where FIP comes in. It attempts to neutralize the affects do defense and give you an ERA for a pitcher based on things they can control- strikeouts, walks, home runs.
Vidal Nuno has been awful this year, but the Yankee defense hasn’t helped him. Nuno’s FIP is 5.15, but his ERA is 5.42. Basically, he should be a bit better than his numbers suggest, but a FIP over 5 is still bad.
McCarthy has been bad, but the Arizona defense is to blame for a bunch of that. His ERA is 5.02, but his FIP is 3.79. If you look at his raw numbers compared to Nuno this makes sense, he records more strikeouts, walks batters at about half the rate as Nuno, and gives up fewer home runs. Using WAR, he is about one win better than Nuno so far.
But there are two problems with this analysis. The Yankee defense will not help him and he is switching to the AL. He should still be better than Nuno, but this is not a huge upgrade. It is more like adding a fifth starter in exchange for someone who should not be starting. Value is created, but that is more a factor of how big some of holes the Yankees have to fill are than the talent of the player they acquired.
UPDATE. Yankees have DFAed Soriano. Not a shock, but it does make you wonder who is coming up and what their role will be. Maybe this means Jose Pirella’s time has arrived? We probably won’t find out until after the game today or tomorrow as the Yankees have recalled Brian Billings for now.
