Yankees left-hander Jacob Lindgren will have Tommy John surgery Friday, an injury that likely will sideline him until the 2018 season.
New York said Wednesday that team physician Dr. Christopher Ahmad will operate at New York-Presbyterian Hospital.
Lindgren, 23, was a second-round draft pick in 2014 and made his major league debut on May 25 last year. He showed promise in seven relief appearances through June 12 and was sent back to Triple-A the following day. The Yankees said June 21 he needed surgery to remove a bone spur from his pitching elbow.
