Phil Hughes suffered "a setback" while throwing a bullpen session Monday afternoon and will be shut down for a few days. The right-hander won't throw while the Yankees figure out what to do with the 24-year-old. Hughes, who has suffered a mysterious loss of velocity in his fastball throughout spring training and his first three starts this season, described the feeling as "just a lot of deadness" in the area of his right shoulder and bicep. He cut short his throwing session after approximately 20 pitches after telling pitching coach Larry Rothschild, "It felt like I just had nothing there."
