After having medical tests done the past two days to figure out what has stolen the speed from his fastball, Phil Hughes is going to see a specialist to determine if he has thoracic outlet syndrome, according to Yankees manager Joe Girardi. In one of the tests Hughes underwent, Girardi said there was a low-level frequency of the syndrome. "We are not saying that he has it," Girardi said. "We are not saying that he doesn't. A real low-level risk of thoracic outlet syndrome, which is basically a circulatory problem."
