Blue Jays have decisions to make on catching, 'pen

TAMPA, Fla. -- The Blue Jays would like to at least tentatively finalize their 25-man roster within the next couple of days.

Toronto manager John Gibbons said on Sunday morning that he would like to have the roster in place before the club heads north for a pair of exhibition games Friday and Saturday in Montreal.

The main decisions that have to be made before the 25-man roster can be set are the backup catcher situation and the final spot in the bullpen.

"We'll have a good idea before that, what the roster is going to look like," Gibbons said of the trip to Montreal for a pair of games vs. the Mets. "We'll bring some extra guys with us anyways, but we'll know within the next couple of days."

The Blue Jays also still have to decide the final spot in the rotation, but that likely won't have a direct impact on the 25-man roster. Dustin McGowan, Todd Redmond, Esmil Rogers and J.A. Happ are all competing for the last job available, but there's room for all four on the team if Toronto goes with an eight-man bullpen.

Right-hander Jeremy Jeffress also is in the mix for a role in relief. He is out of options on his contract and cannot be optioned to the Minors without clearing waivers. Jeffress had a rough start to Spring Training but is coming off a strong outing vs. the Rays and has a 2.79 ERA in 9 2/3 innings.

The backup catcher job is between Josh Thole and Erik Kratz. One of the main responsibilities will be catching knuckleballer R.A. Dickey, and while Thole has more familiarity with the No. 1 starter, it's Kratz that appears to have the edge because of his abilities with the bat.

"The No. 1 job is going to be catching Dickey," Gibbons said. "You want some offense, but the No. 1 thing is they have to be able to catch Dickey. I think they've both done a good job, so it's a tough call."

Reyes out of lineup due to tight left hamstring

TAMPA, Fla. -- Shortstop Jose Reyes was held out of the Blue Jays' lineup on Sunday afternoon as he remains day to day with a tight left hamstring.

Reyes suffered the injury during Saturday afternoon's game against the Tigers. It has been described by the club as being a minor ailment, and he's not expected to miss a significant period of time.

The fear is that the discomfort could linger, but as of now it seems like a normal amount of tightness that happens with a lot of players towards the end of a long Spring Training.

"He feels a little better," Blue Jays manager John Gibbons said on Sunday morning. "We still don't think it's a big deal. Day to day."

Reyes has dealt with hamstring issues in the past. In 2011, Reyes had two stints on the disabled list and missed a total of 29 games with a left hamstring issue. He also had a much more severe problem in 2004 when the All-Star shortstop missed 66 games due to a right hamstring injury.

The 30-year-old is hitting .255 in 17 games this spring. He also has three doubles and five runs scored to go with three walks.

Worth noting

• Blue Jays right-hander Todd Redmond will be shaving his head this week to help raise awareness and money for the fight against pediatric cancer.

"I'm going to shave my head [with], I think, a No. 1 [razor], but I'm shooting for a two just so I could have a little bit of hair on there," Redmond said. "But anything to help the kids. It's a good cause."
