The spectacular rookie has been diagnosed with rotator cuff tendinitis.
The Mets have placed Jacob deGrom on the disabled list with rotator cuff tendinitis and recalled Rafael Montero to take his place in the starting rotation. deGrom has done nothing but impress since being called up in May, and his best work has come lately. He was named the National League Rookie of the Month in July, and it appeared that he would be one of the contenders for Rookie of the Year honors at the end of the season. Then, the rumblings began. It was reported earlier this week that deGrom was feeling shoulder discomfort and would require an MRI.
While this is certainly disappointing news, there are several positives: deGrom's injury does not seem severe, and he should be able to pitch again soon. In the meantime, Montero gets another shot to show what he can do at the major league level. After struggling in his first stint with the club, Montero has been very effective in Triple-A, posting a 2.26 ERA with 26 strikeouts over his last four starts.
