TAMPA, Fla. — Yankees left-hander Andy Pettitte is scheduled to pitch in a minor league game Sunday.

Pettitte, originally slated to start the Yankees' second game of the regular season on Wednesday, has been slowed by back spasms. If all goes well, he likely will make his first start of the season tomorrow or Saturday.

"We're going to see how it feels and try and stretch it out," Pettitte said. "Then figure out what I'm going to do after that game."

Pettitte threw off a bullpen mound Wednesday and will do it again tomorrow. He hasn't pitched in a game since March 17.

"I woke up this morning and I can definitely say it felt as good today as it did yesterday, and maybe even a little bit better," Pettitte said. "The bullpen yesterday didn't set me back at all. So that was positive."
