Matt Harvey will have season-ending surgery performed by Dr. Robert Thompson in St. Louis, his agent Scott Boras told Adam Rubin of ESPN.
Harvey, who has symptoms consistent with thoracic outlet syndrome, was weighing whether to have the surgery or receive a non-surgical injection.
He has had trouble commanding the baseball since Spring Training due to loss of feeling in his fingertips, Jon Heyman reported.
Even if Harvey didn't opt for surgery now, he would've eventually needed to have it, Alderson said,
Harvey told the Mets after his last start that he was experiencing shoulder discomfort.
"His arm just felt like he was dead," Terry Collins said about how Harvey described his condition after his last start. "I don't want to sound like woe is me, but woe is us."
He was placed on the 15-day disabled list with right shoulder discomfort on Wednesday.
Harvey has posted a 4.86 ERA and 1.47 WHIP while striking out 76 batters in 92.2 innings (17 starts) this season.
Logan Verrett will start in place of Harvey this Saturday agains the Nationals, Collins said.
Alderson added that Zack Wheeler is not a realistic option to replace Harvey in the rotation anytime soon, and that there is no way to project when Wheeler will return to the Mets.
According to FanDuel's injury expert Will Carroll, plenty of pitchers have had this surgery and it takes about six months to get back on a mound. So, this will end his season, including pitching in the playoffs.

At any rate, at least this might explain some of why his mechanics have been off, which undoubtedly have his mind messed up, and round and round he goes. Between this, the TJ surgery, innings limits last year and his blood clot from Spring Training, the kid clearly isn't catching any breaks. I have no idea what to expect from him at this point. And, much like when he disappeared in 2013, I'm afraid he'll be out of sight, out of mind until he gets back throwing on a mound.
