According to the Boston Herald, the Red Sox are expected to be without David Ortiz for at least a month, if not longer.

In the midst of a 6-3 loss in the finale of the Sox’ four-game set with the Orioles, the Herald’s Tony Massarotti reported designated hitter David Ortiz [stats] would be out at least a month, and perhaps longer, with what the team later called a tear in the ECU tendon sheath on the top left side of his left wrist.

“(Ortiz) means so much to our club and he means so much to the game of baseball,” said Sean Casey, one of Ortiz’ possible replacements. “We’re going to have to do without him for a few weeks. We have a lot of good guys in here who will hopefully hold down the fort until David comes back in a few weeks.”

Besides the usual presence Ortiz has provided in the middle of the lineup, he also had been one of the team’s most consistent hitters of late until straining his wrist on a swing in the ninth inning Saturday night.

Tough break for the BoSox with the first place Rays in town for a three game set. The club called up Triple-A prospect Chris Carter, but it’s unclear if he’ll be the one to replace Ortiz in the lineup. Sean Casey, Coco Crisp, Jacoby Ellsbury and Jeff Bailey are likely to see increased playing time, too.
