Pirates manager Clint Hurdle said scouting reports he received on Charlie Morton's (elbow) rehab start with Double-A Altoona on Tuesday were "excellent."

Morton allowed just one hit, walked two and struck out three over four scoreless innings. The right-hander is expected to make at least two more rehab start before rejoining the Pirates' rotation.

Charlie Morton (elbow) will throw two innings in an extended spring training game on Monday.

Morton has thrown a handful of bullpen sessions -- the most recent one being a 36-pitch effort on Friday -- and is ready to test things out in game action. The right-hander is expected to rejoin the Pirates around midseason, though it might not be as a member of the rotation.

Pirates placed Charlie Morton on the 15-day disabled list, retroactive to March 22, with a right elbow injury.

Morton is ahead of schedule in his recovery from Tommy John surgery, but still shouldn't be expected to rejoin the Pirates until after the All-Star break. Even when healthy, Morton won't be guaranteed a spot in the starting rotation.
