You had said the Yankees were falling apart, not their rotation. Pitchers do tend to get a little worn out by the end of August. Wainright has had trouble in August and Gallardo had a terrible August. They are both All Star pitchers. Buchholz had the worst start of the season his last time out. Many teams have starters go through tough stretches in late August, but that highlights the importance of a strong bullpen. The Yankee bullpen has been pretty strong throughout, which is why the team has not fallen apart. Their starters should rebound, except maybe for Burnett. Pettitte coming back will give a big boost. In the post season, they'll only need one more pitcher to throw out there with CC and Pettitte. Burnett can be on a short short leash with Hughes in the pen.
