Daisuke Matsuzaka back in rotation

ST. PETERSBURG, Fla. -- Boston Red Sox pitcher Daisuke Matsuzaka has been penciled in to start on Thursday against the Baltimore Orioles at Camden Yards.

"We feel that's pretty realistic," said Red Sox manager Terry Francona. "It allows him to pitch with confidence and doesn't screw everybody else up."

The right-hander suffered a bout of "normal" back soreness while playing catch on flat ground on Wednesday and was scratched from his next scheduled start, Friday night against the Tampa Bay Rays.
