Steven Matz Needs Nerve Repair Surgery

Ever since Steven Matz emerged as a core member of the Mets’ stalwart starting rotation in his 2015 rookie season, his path in the major leagues has been repeatedly derailed by injuries.

Matz and his team have received more disheartening news about his troublesome left elbow, as he was found to have irritation of the ulnar nerve in his left elbow after undergoing a magnetic resonance imaging exam and a CT scan. The Mets said he would have surgery to reposition the nerve. He is not expected to return this season.

It was yet another blow for the Mets’ rotation, which began this season with high expectations before being decimated by injuries.

Matz was originally scheduled to start against the Arizona Diamondbacks on Tuesday, but Mets Manager Terry Collins said Tommy Milone would make the start instead.

Matz missed the first two months of this season with left elbow inflammation. Upon returning, he posted a 2-1 record with a 2.12 earned run average in his first five starts. But then came a sharp drop-off in his performance, and Matz is now 2-7 with a 6.08 E.R.A.

In May 2010, Matz had Tommy John surgery to repair a tear of his left ulnar collateral ligament. Last October, Matz had surgery to remove bone spurs from his left elbow, ending his season.
