Scott Baker shut down a month

GOODYEAR, Ariz. -- Chicago Cubs pitcher Scott Baker won't pitch again for at least a month after doctors concluded he has a muscle strain in his arm as he attempts to return from the Tommy John surgery that caused him to miss all of last season.

"It's bad news," manager Dale Sveum said. "It's somebody obviously we were counting on to be there in mid-April or May if everything went alright."

But Sveum was quick to point out it could have been worse. Many pitchers coming back from that surgery experience at least one setback and this is Baker's first.

"It's obviously a setback but it's not to where he won't be able to pitch this season," Sveum stated.

Meanwhile, third baseman Ian Stewart will remain in Arizona after the team breaks camp later this week as he continues to rehab a left quad ailment. If all goes well he'll start a rehab assignment in about two weeks, according to the club.

"You're looking at end of April," Sveum said regarding Stewart's possible return to the Cubs.

The Cubs sent pitcher Rafael Dolis to Triple-A Iowa on Sunday, leaving three pitchers for one spot in the bullpen -- lefthander Hisanori Takahashi along with righties Zach Putnam and Cory Wade.
