PITTSBURGH (AP) — Chris Archer won’t pitch for the Pittsburgh Pirates in 2020 and his time with the club may be over.

Pittsburgh announced Wednesday that 31-year-old Archer underwent surgery to relieve symptoms of thoracic outlet syndrome. The procedure was conducted on Tuesday in St. Louis, and the Pirates said Archer will not be available this season if Major League Baseball finds a way to put together a truncated schedule.

The Pirates were banking on a bounce back year by Archer, who is 6-12 with a 4.92 ERA in 33 starts since he was acquired from Tampa Bay at the 2018 trade deadline for outfielder Austin Meadows and pitcher Tyler Glasnow. Archer has struggled to find any consistency with the Pirates, while Meadows became an All-Star last season and Glasnow also blossomed.

Archer’s contract includes a $9 million salary this year, but he will receive only a portion due to the coronavirus pandemic. Pittsburgh holds an $11 million club option for 2021, with a $250,000 buyout.
