sheer idiocy for the most part.
Until tonight, Wang had been one of the best pitchers in the AL, hands down. He gives innings, he is consistent and he can be damn near dominant on a nightly basis.
If you wish to be concerned, then go off todays's start which was very uncharacteristic or the fact that he seems to flatten out that sinker after 6 innings. In his last start, Molina had him throwing more 4 seamers and changeups to try and get his swing and miss capability up. He is trying things.
But in terms of him being a disappointment, cmon now, give me a break. He is still under a 4ERA and gives more innings per start than most any pitcher in baseball (once again, until tonight). If he gets that sinker to stay down, he'll recover what he was prior to tonight.
So if you want to cry about one bad start, then cry about the fact that his sinker was belt high all game long. But I wouldnt cry about Wang, I'd take him over nearly anyone in the AL sans Santana.
