Veteran reliever Kent Mercker was asked to describe the lingering soreness he felt in his left elbow. Was it an ache, a dull pain or throbbing? "Um, yeah. You pretty much hit it on the head," Mercker replied. The injury is officially listed as left elbow inflammation, and it was enough to force Mercker onto the 15-day disabled list on Sunday. Right-hander Mike Burns was recalled from Triple-A Louisville, and was expected to arrive some time during the game against Philadelphia.
