BALTIMORE -- Michael Pineda hit his first bump in his Minor League rehabilitation assignment on Sunday, permitting four runs in three innings to the Double-A Binghamton Mets while pitching for the Trenton Thunder.
Working his way back to the big leagues from right labrum surgery, Pineda allowed homers to Cesar Puello and Richard Lucas, walking four and striking out four around four hits in a 67-pitch outing.
"I guess his velocity was fine," Yankees manager Joe Girardi said. "From the box score, it just looks like he didn't pitch as well."
Girardi said that the Yankees have not yet discussed having Pineda join the big league roster when his 30-day rehabilitation assignment is up in early July, and general manager Brian Cashman has said it is possible the Yankees would keep Pineda starting at Triple-A Scranton/Wilkes-Barre.
"I saw that he threw 67 pitches today. He's thrown more," Girardi said. "I know he went three innings today, but if he can help us -- if Brian thinks he can help us -- I'm sure we'd bring him."
