Rays DH Luke Scott is headed to the 15-day disabled list, while 3B Evan Longoria and INF Jeff Keppinger are headed to Triple-A Durham. Scott said he injured his back last Friday while trying to warm up for a pinch-hitting appearance against the Marlins. He said he woke up with a stiff lower back and put a heating pad on it while taking practice swings in the batting cage. "I've been having really, really bad back spasms since Saturday," said Scott, who is hitting .220 with nine homers and 35 RBIs. "I've been trying to get them to go away, but they haven't so far. We have a plan and we'll keep to that plan. It's a difficult situation, but we'll have to make the most of it."
