Matt Harvey undergoes surgery to address thoracic outlet syndrome

CHICAGO -- New York Mets right-hander Matt Harvey underwent season-ending surgery Monday to address thoracic outlet syndrome.

Dr. Robert Thompson performed the procedure in St. Louis, manager Terry Collins said.

Thompson had planned to remove Harvey's top rib, with the goal of relaxing muscles that were constricting a nerve bridging the neck and shoulder. The nerve compression caused weakness in Harvey's pitching arm and a loss of feeling in his fingers.

Agent Scott Boras has estimated a six-month recovery time for Harvey, which would leave him ample time to be ready for the 2017 season.

Harvey went 4-10 with a 4.86 ERA in 17 starts before getting shut down.

Logan Verrett has inherited Harvey's rotation spot. Verrett limited the Philadelphia Phillies to two runs on eight hits and one walk in six innings in a no-decision on Saturday.
