Mets' Harvey to have season-ending surgery for TOS

NEW YORK (AP) The New York Mets say Matt Harvey will have season-ending surgery for his thoracic outlet syndrome injury.

The team says the operation will be performed in St. Louis by Dr. Robert Thompson but didn't announce a date.

General manager Sandy Alderson said in a statement Friday that he and manager Terry Collins met with the right-hander and expressed their support for the decision. Alderson says the clubs knows Harvey ''will work as hard as possible to get back on the field for the 2017 season.''

Collins says Harvey made no excuses for his poor performance, and they were relieved to know why he struggled so badly this season. The former ace went 4-10 with a 4.86 ERA in 17 starts.

Thoracic outlet syndrome is caused by the compression of nerves, blood vessels or both in the area between the neck and armpit. After his outing Monday, the 27-year-old Harvey complained of some common symptoms.
