He went on the 15-day disabled list July 30 with a right forearm strain and has made a Minor League rehab start Sunday with Double-A Trenton. He threw 42 pitches in three innings, giving up four hits and two earned runs. Of his 42 pitches, 30 were strikes.
Last week, Girardi said he wasn't sure if Pineda would need more than one Minor League rehab start. The Yankees are hopeful that Pineda will be back in the rotation by Sept. 1 and are considering a six-man rotation in September.
Pineda is 9-7 with a 3.97 ERA in 19 starts this season. He's registered 117 strikeouts in 118 total innings.
Girardi indicated he's hopeful that this will be the last rehab start Pineda needs.
"We just feel it will help him be a little bit sharper when he comes back. He threw 45 pitches. I don't worry so much about the pitch count because I think his arm is in shape, but just want to make sure he feels sharp," Girardi said. "Could that change if something blew up and went crazy today? Yes. But our plans are for him to make another start and then come back and pitch."
