Pineda has been on the disabled list with a strained a shoulder since April. He had surgery to repair a torn labrum in the same shoulder in 2012.
Pineda's last major league start ended when he was ejected in the second inning for smearing the ball with pine tar. The incident earned Pineda a ten-game suspension. He was injured while pitching in a simulated game during his suspension.
Pineda made two rehab starts this month with Triple A-Scranton/Wilkes-Barre and was scheduled to make one more, but he will be called up to the majors instead.
In four starts before his injury, Pineda had a 1.83 ERA and 1.017 WHIP.
The Yankees are in third place in the AL East, six games behind the Orioles. The teams have 10 more meetings left this season.
