The Mets announced Monday that after Matz underwent an MRI and CT scan on his left elbow, he was diagnosed with irritation of the ulnar nerve. Surgery "has been recommended" and will be scheduled soon, according to the team.
"This is not an injury," Collins said Monday in reference to Matz, per Abbey Mastracco of NJ.com. "This is a situation of, he needs to shut it down for a little while. I haven't talked to Sandy about it, so I'm not going to get into the whole medical thing just yet, but if he had to, he could pitch tomorrow. We're going to probably put him on the DL."
A prolonged injury could explain Matz's yearlong struggles. After posting a 3.40 ERA in 22 starts in 2016, he has just a 2-7 record this season with a 6.08 ERA. He allowed seven runs (six earned) in just 3.1 innings in his last start against the New York Yankees on Thursday.
After missing the first two months of the year with an elbow injury, it's clear he never got on track.
The Mets are also no strangers to injury disputes. Noah Syndergaard went to the DL this year after refusing to get an MRI, while Matt Harvey pitched with a stress injury in his shoulder before going on the DL. Starters Seth Lugo and Zack Wheeler are also out with injuries in an unlucky year for the Mets rotation.
Although New York is far out of the playoff race with 40 games left in the season, the team has to be concerned about the future health of its young pitchers.
