Hmm, in the last half hour, the ump called the last strike on Carlos Pena (Rays-Rangers) on a pitch that was 6 inches outside, with a runner on in extra innings. Pena would have been the tying run. In Yankees-Orioles, the 1st base ump called Teixera out sliding into first base for the final out, and he was clearly safe. A safe call would have tied the game. Don't say that bad calls don't lose games....
Incidentally, when Pena complained, the ump threw him out, even though the game was over. Umps need a good, strong dressing down from the commissioner, but he is far too weak to go after that.
