NEW YORK (AP) The New York Mets have placed left-handed pitcher Steven Matz on the 15-day disabled list, retroactive to Aug. 15, with shoulder tightness.
The Mets say the rookie underwent an MRI on Monday that revealed no structural damage to his shoulder.
Matz was scratched from his Friday start. He had taken a no-hitter into the eighth against San Diego in his last start, when he was removed after 105 pitches.
Matz is 9-8 with a 3.40 ERA. He joins Matt Harvey and Zack Wheeler among New York's heralded young pitchers on the DL.
The Mets recalled right-handed pitcher Robert Gsellman from Triple-A Las Vegas.
The 23-year-old Gsellman opened the season with Double-A Binghamton and went 3-4 with a 2.71 ERA in 11 starts before being promoted to Las Vegas. In nine starts for the 51s, Gsellman is 1-5 with a 5.73 ERA.
