Pedro Martinez threw 64 pitches over four innings in a simulated game for the Phillies on Tuesday.

"Real, real good," Martinez told The Associated Press of how he felt after the appearance. "Four innings, I was able to do that. I didn't feel tired. I felt like I could still do a little bit more."

Martinez is scheduled to throw off a bullpen mound on Thursday, which could lead to him throwing another simulated game or pitching in a minor league game Sunday.
