Chamberlain induced a flyout, a popout and a groundout as he started against the Lakeland Tigers in Lakeland, Fla., marking his fifth appearance.
The Yankees continue to believe that Chamberlain -- who is returning from Tommy John surgery and an open dislocation of his right ankle -- could rejoin them when his 30-day rehab clock expires on Aug. 6. He has been clocked in the high 90's with his fastball.
"I'm hoping at some point we might see a little bit of a tape," Yankees manager Joe Girardi said. "He's going to come and throw a bullpen for us while we're on this homestand. We'll get a chance to see him there, but a bullpen is different from a game, no doubt about it."
