General Manager Brian Cashman noticed that Hughes was not throwing as hard as usual. His fastballs were averaging 88 to 91 miles an hour, Cashman said, when they should have been 91 to 93. ?I don?t know why,? Cashman said. ?It?s our job to continue to look and see if there?s anything mechanically. He could still be just building arm strength from being down for so long. ?It?s starting to improve, though. His last two outings, he?s been popping a few more high-velocity fastballs. But he?s got more arm strength than he?s shown lately. He?s not coming at hitters with his full ability yet.? Hughes has a 6.11 earned run average in five starts since coming off a three-month stay on the disabled list for hamstring and ankle injuries. Manager Joe Torre said he was not concerned about Hughes?s velocity. The radar gun readings in the ballpark, Torre said, were lower than the ones he noticed on the Tigers? telecast when he went in the clubhouse during the game. Hughes said: ?There was life on my fastball yesterday. I thought it was good. I was getting some swings and misses and a lot of foul tips and stuff like that. I?m always working on building my arm strength back, but it?s not something right now where it?s really bad."
