Boston designated hitter David Ortiz has faced Pettitte a lot over the years.
"The Yankees gave him a chance to come back and perform because they think he can come back and perform, but he's not 25 anymore. Know what I'm saying? So the Yankees also know they're running the risk of him coming back and not performing well. So they know we are up to all those challenges," Ortiz said.
"If he comes back and doesn't perform well, you guys are just going to say, 'Well, he's not 25 anymore. He took a year off.' He's what, 39? All that goes against him. If he comes back and performs well, 'The guy is a natural,'" he said.
New York currently has four starters, besides Pettitte, looking to fill three rotation spots behind Sabathia and Kuroda.
"It's one of those things, I feel there's nothing but upside here," Cashman said.
