Ross to undergo surgery for thoracic outlet syndrome
San Diego Padres pitcher Tyson Ross will undergo surgery Thursday to relieve symptoms of thoracic outlet syndrome, manager Andy Green told The San Diego Union-Tribune's Dennis Lin.
The procedure is expected to sideline Ross for four-to-six months, which means he could be ready for spring training, but could also miss early regular-season action.
Thoracic outlet syndrome occurs when blood vessels or nerves between the collarbone and the first rib are compressed, which can cause shoulder and neck pain, as well as numbness.
Dr. Robert Thompson, the surgeon set to perform the operation on Ross, performed the same procedure on Matt Harvey, Chris Young, and Clayton Richard.
Ross, an All-Star in 2014, started Opening Day for the Padres in 2016 before shoulder inflammation derailed his season. He pitched one High Single-A rehab game in August, but could never overcome the shoulder discomfort that limited him to that lone start for San Diego.
The 29-year-old, set for free agency in 2017, has appeared in 153 games - starting 102 of them - over the last seven seasons, posting a 32-53 record to go along with a 3.64 ERA and a 1.32 WHIP.
