So no bad news is good news for Phil Hughes. Here’s Ben Shipgel in the Times:

All of Hughes’s tests Monday came back negative for circulatory and vascular problems, the Yankees said. The development deepens the mystery regarding Hughes’s lack of arm strength but spreads a feeling of relief that thoracic outlet syndrome is not the cause.

“I’m not sure if he has that, what they have to do and how long you don’t have him if that’s what he has,” Manager Joe Girardi said. “It makes me feel better.”

Hughes traveled to St. Louis to meet with Dr. Robert William Thompson, a renowned vascular surgeon, to confirm or to rule out that he had thoracic outlet syndrome.

Now he will return on Tuesday to New York, despite having a locker set up for him in the visiting clubhouse, to rehabilitate his shoulder as the Yankees redouble their efforts to discover why it feels numb when he pitches.

Curious. Very curious.
