After the Yankees' win on Wednesday night, Yankees Manager Joe Girardi commented in the postgame press conference on the state of his young pitcher Phil Hughes about his MRI test results.

“One of the tests they did with Phil showed and we're not saying that he has it and we're not saying that he doesn't, but a real low level risk of Thoracic Outlet Syndrome, which is basically a circulatory problem,” Girardi told the media. “We're sending him to a specialist in St. Louis to either rule it out or rule that he does have it.” That specialist is Dr. William Thompson.

Thoracic Outlet Syndrome or TOS is according to MayoClinic.com, “A group of disorders that occur when the blood vessels or nerves in the thoracic outlet, the space between your collarbone and your first rib become compressed. This can cause pain in your shoulders and neck and numbness in your fingers.” It's usually caused by physical trauma of some kind, which includes sports-related activities.

Girardi would not give an answer one way or another on length of time an injury like this would keep a player out, but he did say that he would wait to give any further details on anything, including whether he even has TOS after Hughes saw the specialist.

It continues to be the waiting game on the status of Phil Hughes, but at least this might give Hughes and the Yankees a clearer picture of what they may be dealing with.
