The Yankees said Torres has a torn ligament in his left elbow but is expected to recover after surgery in time for spring training next year.
Torres was seen by the team's head physician, Dr. Christopher Ahmad, at Presbyterian Hospital in New York and diagnosed with a torn ulnar collateral ligament in his left elbow.
The 20-year-old Torres has risen quickly through the Yankees' minor league system, but the torn UCL and subsequent surgery puts an end to any hopes of a 2017 major league debut.
