Rodon (elbow/hamstring) threw on flat ground and a bit off the mound Wednesday, Greg Joyce of the New York Post reports.
Rodon -- who is on the 15-day injured list as he recovers from elbow surgery -- felt right hamstring tightness while doing some running Tuesday but has continued throwing. He will meet with the Yankees trainers when the team returns home later this week as the club evaluates how much the hamstring issue might set him back. Prior to the hamstring problem, Rodon had tentatively been slated for his season debut in late April.
