Hughes to have season-ending shoulder surgery

The Minnesota Twins' tumultuous season received some additional poor news Tuesday when the club announced right-hander Phil Hughes will undergo season-ending shoulder surgery to alleviate thoracic outlet syndrome.

Surgery will take place July 6 and will require the removal of a rib.

General manager Terry Ryan said before Tuesday's game against the Chicago White Sox he expects the 30-year-old to be ready for spring training.

Hughes was already on the 60-day disabled list for an unrelated femoral fracture above his left kneecap sustained June 9, when a line drive knocked him out of a game.

Thoracic outlet syndrome is a group of disorders that occur when the blood vessels or nerves in the space between your collarbone and your first rib become compressed, according to the Mayo Clinic. It may cause pain in the shoulders and neck and numbness in the fingers.

Thoracic outlet syndrome has also affected pitchers in the past including Drew VerHagen of the Detroit Tigers and once-dominant San Diego Padres reliever Mike Adams.

Hughes was just 1-7 with a 5.95 ERA for the major-league worst Twins prior to his injury.

He's still owed $39.6 million over the next three years.
