Mets opening day starting pitcher Matt Harvey will undergo season-ending surgery due to thoracic outlet syndrome, agent Scott Boras told Adam Rubin of ESPN New York.

Just one day ago, it was revealed what condition Harvey had and the news was that he was mulling over non-surgical options, but it appears he has decided to go under the knife. It's a risk, for sure, as several pitchers have had the procedure and never been the same, such as Chris Carpenter and Jeremy Bonderman. Others have bounced back, like Jaime Garcia and Kenny Rogers.

Harvey, 27, finishes his 2016 season 4-10 with a 4.86 ERA, 1.47 WHIP and 76 strikeouts in 92 2/3 innings. He was expected to anchor the Mets very talented rotation, as he took the ball opening night in Kansas City against the defending champs. Instead, he's had decreased velocity and stamina throughout the season. Now we know why.

With Harvey down, the Mets still have a very good front four in the rotation in Noah Syndergaard, Jacob deGrom, Steven Matz and Bartolo Colon. With Zack Wheeler still recovering from Tommy John surgery -- he appears to be at least a month away -- righty Logan Verrett figures to stick in the rotation. In five starts this season, Verrett is 1-3 with a 5.32 ERA.

The defending NL champion Mets are 47-38 this season, three games back of the Nationals in the NL East and holding down the top Wild Card spot in the NL.
