What gives Mo?!

I don't understand it? When he comes into a tie game is he trying to pitch differently than if it was a save situation? This year has been so uncharacteristic of him. He's always proved to be calm and clutch and he's done nothing but prove it this year again, hence the 26 out of 26 in saves. Does he have Billy Wagner disease, that unless it's a save he can't perform? Who am I kidding, Billy Wagner can't perform in any situation (had to get that in there)! I just can't make sense of it all - maybe I'm making a bigger deal out of this then there needs to be, I mean he's only cost us 4 losses compared to the 26 saves plus the 4 wins hes racked up this year. Then again 4 more wins we'd be in second place 1.5 games behind Tampa (which in any universe sounds ridiculous and his a whole other rant!). Well there is still 2 months of baseball left and I'm confident that the Yankees will rise to the top as always!
