Daisuke Matsuzaka, RHP, Red Sox - We’ll have to get an explanation on this one, but a source told MLB.com reporter Maureen Mullen that Matsuzaka unexpectedly took a week off from Athletes’ Performance Institute in Tempe, Ariz. Mullen wrote that the respite does not appear to be injury-related. Right now there’s no reason to believe Matsuzaka is abandoning his conditioning, but with Dice-K, who knows?
