Today was Pettitte's throw day, and the typical side session is about 50 pitches at 90-95% intensity. Pettitte only threw 14 pitches, so unless he threw a lot of warmup pitches, it was a smart way to use him. It's the second time Pettitte has been used in relief in between starts this year. In Colorado, Josh Fogg has been used the same way. Personally, I'm all for it. I know it's perfectly safe to pitch him today. But I don't think it's worth it to throw him out there against one of the best hitters in the game to try and beat the Red Sox in April, especially when you consider the injuries in their rotation. If it's perfectly safe for Pettitte to pitch, what do injuries in the rotation have to do with anything? Pettitte also made a relief appearance against Baltimore a couple of weeks ago, so it wasn't just a case of pulling out all the stops to beat Boston. This might be the only way I've ever been impressed with Joe Torre's handling of his pitching staff, and I'd be all for doing it with other veteran pitchers.
