Jason Kubel has been out of the starting lineup the past two games after aggravating his left quadriceps injury. The injury forced him onto the disabled list earlier this season. "Just trying to get over that," Kubel said. "We decided to give it a few days rest." Kubel was batting .333/.375/.600 with two homers and six RBI before going down with the injury on April 9 and he's struggled mightily since, batting .167 since his activation. Arizona begins a three-game series Friday against Florida and Kubel's former Twins teammate Kevin Slowey. Cody Ross and A.J. Pollock will pick up additional at-bats if Kubel can't play.
