Two of Matz's teammates, Erik Goeddel and Jacob deGrom, have each come back from the same surgery. The procedure ended deGrom's 2016 season around the same point last year, and he returned ready to go for the following Spring Training. deGrom has been stellar this season, going 13-7 with a 3.49 ERA.
On Thursday, Matz told reporters he will will return to the doctor Friday to be fitted for a brace, followed by resting for 10 days. Beyond that, Matz will again meet with doctors and begin physical therapy.
"I think I'll just wait and see how it progresses, and then I'll evaluate it from there," Matz said, "but there's no rush."
The ulnar collateral ligament is what's associated with Tommy John surgery, which Matz had shortly after being selected by the Mets in the second round of the 2009 Draft. Injuries have shelved him at various points since his debut in 2015. He missed the first two months of 2017 with an elbow injury that ultimately led to his most recent surgery. The left-hander struggled this year, ending his season 2-7 with a 6.08 ERA, the highest mark of his career.
However, Matz was relieved there was a reason behind the constant discomfort he felt all year.
"I'm happy that there's an answer to it," he said.
