The Red Sox entered Saturday's game in fifth place in the AL East, seven games behind the division-leading Rays, marking the furthest behind the Sox have been all year.
Daisuke Matsuzaka, recovering from Tommy John surgery, is still on schedule to make his third rehab start on Monday night for Triple-A Pawtucket. He's 0-1 with a 4.15 ERA and 10 strikeouts in his two rehab starts thus far.
Valentine said Alfredo Aceves, who threw 2 2/3 innings (38 pitches) of scoreless ball with six strikeouts Friday, would likely be available for Saturday's game if he was needed.
Valentine said he talked to injured left fielder Carl Crawford on Friday, and Crawford said he was feeling good. "It's just a little thickness in his elbow," Valentine said. "As soon as that thickness goes away ... he'll be ready for baseball activities."
Kevin Youkilis (back tightness) had an MRI, but as of Saturday morning, the Red Sox had not gotten the results. Valentine isn't yet sure if Youkilis or Crawford will travel with the team to Kansas City for a three-game series that starts on Monday.
