Rehabbing Phil Hughes twisted his left ankle Thursday, and even though the Bombers insist it’s no big deal, they scheduled their young phenom for an MRI.

“Hughes turned his ankle a little, nothing serious. He was doing his agility drills and his spike got caught. They don’t think it’s anything. It may set him back a couple of days,” Joe Torre said. “[GM Brian] Cashman told me he rolled it a little bit. They didn’t seem to be concerned at all, but there’s a chance it may set him back a couple of days.”

Hughes was expected to have an MRI either last night or today. The rookie — put on the DL May 3 with a strained left hamstring _ was expected to miss about six weeks, and the Yanks are still hoping he’ll be back in mid or late June.
