Pettitte is expected to throw a bullpen Saturday and could throw a simulated game if all goes well. He is on track to return around his first eligible date of June 1.

"We have it mapped or semi-mapped out," Girardi said. "I don’t know if it will be the first day, but it will be shortly after that."

Pettitte will complete long toss following playing catch. That will be followed by a bullpen session and then a simulated game. Pettitte will do his work with the Yankees and not at the minor-league complex. 

"They're giving him five or six days off from throwing," manager Joe Girardi said. "He's not scheduled to throw yet."

Girardi said that Pettitte may throw a simulated game instead of going on a real rehab assignment for his strained trapezius muscle. 

"He is 40 years old, and we're probably going to go through this probably a little bit," Girardi told reporters after the game.

You don't often see pitchers throwing 180 innings in their 40s, but for a non-strikeout pitcher like Pettitte to make a significant impact in Fantasy, he'll pretty much need to do that. If he's perpetually at risk of missing his next start because of this ache or that pain, you have to ask yourself if he's really worth the trouble.

Even if the Yankees put him on the DL, which seems likely, you shouldn't feel like you have to cut a Brandon Beachy or Adam Eaton type to keep him on yours.
