GOODYEAR, Ariz. -- Reds left-handed reliever Bill Bray was restricted from workouts the past couple of days because of a sore left groin muscle. The injury is not considered serious, however.

Bray has been getting treatment and was able to long toss from 150 feet on Tuesday. He has yet to participate in live batting practice sessions against Reds hitters.

"I should be back by the weekend," Bray said on Wednesday. "It happened on the mound during my second bullpen. They're being cautious and don't want it to get worse. I feel good."

Bray, 28, is coming off of one of his best seasons, in which he went 5-3 with a 2.79 ERA. His 79 appearances in 2011 led the club and tied for second in the National League.

Baker to determine roles for duo behind dish

GOODYEAR, Ariz. -- Just because top Reds prospect Devin Mesoraco will be in the Majors this season, it doesn't mean that catcher Ryan Hanigan will only get scraps of playing time behind the plate.

Manager Dusty Baker plans to have Hanigan do more than just catch Bronson Arroyo every fifth day.

"Wasn't he more than a one out of five [pitchers] last year?" Baker said on Wednesday. "Don't assume he's one out of five now."

Hanigan, 31, batted .267 with six home runs and 31 RBIs last season. He played a career-high 91 games, and would have played more if he hadn't suffered a back injury that ended his season by mid-September.

Mesoraco, 23, batted .180 in 18 big league games as a September callup, but his track record in the Minors says he should be a good hitter.

Baker hasn't come up with a plan on how to divide the catchers' playing time. The past three seasons, he had a successful tandem with Hanigan and Ramon Hernandez.

"I don't know how it's going to play out," Baker said. "A lot of it depends on what kind of progress Mesoraco shows. If he continues on the path, he's the catcher of the future, big time. When that future is, it's undecided."

Worth noting

• The Reds will hold a two-inning intrasquad game on Friday. Their pitchers will be Andrew Brackman, Josh Judy, Donnie Joseph and Nick Christiani.

"This is mostly for the pitchers that need the work," manager Dusty Baker said. "Not many of my regulars are going to play."

• A 10 a.m. "B" game has been scheduled between the Reds and Mariners on March 5.

• No spring starting rotation has been revealed by the Reds, including their starter for Saturday's Cactus League opener against the Indians.

"That's Bryan's department there," Baker said of pitching coach Bryan Price. "It always has been. Then I get it and I OK it."
