Ohlendorf's velocity touched as high as 94 mph in the outing, which was the right-hander's first game action since his April 7 start in Pittsburgh. Ohlendorf reported no discomfort or issues with his back afterward.
"It was very encouraging," said director of development Kyle Stark, who was on hand to watch Ohlendorf throw. "I was encouraged by the health, the way the ball came out of his hand and the progress to where he is at this point."
Ohlendorf will make a second Minor League rehab start on Wednesday, either with Double-A Altoona or high-A Bradenton. Assuming there are no setbacks, the righty will then return to the Pirates' rotation on May 10 to face the Reds in the opening game of a three-game series at PNC Park.
