First came the decrease in Phil Hughes’s velocity, and then the subsequent placement on the disabled list with a “dead arm,” which is really just another way of saying a “tired arm that we otherwise can’t explain.” And now — just days after Hughes had been encouraged by a throwing session in Baltimore on Saturday — he had to cut a bullpen session short yesterday because he felt “deadness” in his arm after throwing a dozen or so pitches, and he’s been shut down again. He’ll undergo an MRI exam and a circulation test today, and even Hughes admits he’s “worried” that the problem hasn’t gone away. Hughes says he doesn’t feel pain in his shoulder or biceps, and describes his issues thusly: “If someone hits you in the thigh really hard, after that it’s just numb? It’s sort of that feeling.” [Record, NYP]
