The right-hander will go through with season-ending surgery on his shoulder, the Mets announced Friday.

The surgery will address Harvey’s thoracic outlet syndrome, general manager Sandy Alderson said.

“Terry (Collins) and I met with Matt today and although we all feel badly for him, we expressed our support in this decision and know he will work as hard as possible to get back on the field for the 2017 season,” Alderson said.

Agent Scott Boras attributed Harvey’s poor showing this season to the diagnosis. The pitcher is off to the worst start of his major league career, going 4-10 with a 4.86 ERA in 17 starts.

The surgery will be performed by Dr. Robert Thompson in St. Louis, according to the Mets.

Thoracic outlet syndrome is a circulatory issue that can cause pain in the shoulders and neck, as well as numbness and weakness in the fingers.
