The New York Mets injury bug is still biting as the second half of the season unfolds. The latest is All-World pitcher Jacob deGrom. It was announced on Sunday that deGrom will go on the IL with right forearm soreness. This is not totally unexpected as the superstar was feeling pain in his arm and had to shut down a throwing session on Saturday.

Said Jacob: “I’m frustrated. I don’t know what else to say. I guess it’s good news when things structurally look good but then you go out and try to throw a baseball and your form doesn’t feel good. Frustration is very high.”

This is obviously a tough blow to a Mets team that holds a meager 2.5 game lead in the National League East. The diagnosis of forearm tightness and seemingly unknown recovery timeline are even more alarming due to the uncertainty of deGrom’s return.

The 33-year-old deGrom, who leads the majors with a 1.08 ERA, hasn’t pitched since July 7 after dealing with three different physical issues in the first half, including flexor tendinitis in his right arm and shoulder soreness last month. DeGrom further mentioned that his previous injuries, all unrelated, were as a result of swinging the bat. But the forearm issue was not.
