The Boston Red Sox right hand-er Daisuke Matsuzaka was put on the 15-day DL today with a mild right shoulder strain. Dice K did not make it to the second inning Tuesday night against the Athletics, giving up five runs and five hits on 43 pitches. “Our biggest concern is to keep him healthy and productive,” Terry Francona said. “At the moment, it doesn’t seem like we’re there with him. We want him to be able to be Dice-k.”
