Here is the update, from Chad Jennings:
Girardi says nothing new on Hughes right now. Doc will be here later. Might have an update then.
Hughes underwent a second day of medical examinations today, with the team putting him through a battery of tests to see if they can find any sort of explanation for his diminished velocity and tired arm. The Yankees likely refrained from sending Hughes from tests until now because, as medical professionals will tell you, you can often find something that will look anomalous in the arm of a person who throws a baseball for a living, even if the player is perfectly healthy. At this point, however, the Yankees have been left with no choice but to run through the entire repertoire of examinations to see if they can pin Phil’s struggles on a medical problem.
While I am still hoping for the best regarding Phil’s health, I cannot say that I am feeling very optimistic at this point. Unfortunately, this is part of developing young arms into reliable starters. Sometimes they struggle, sometimes they show flashes of brilliance, and more often than not, they get hurt. It’s disappointing, and I hope that Hughes is back in the rotation in short order, but the Yankees need to be patient and exhaust every avenue in determining what is ailing Phil before they throw him back out there.
