DUNEDIN, Fla. -- The Blue Jays are not expected to make the signings of Clay Buchholz and Bud Norris official for at least another day or two, but inside Toronto's clubhouse, the team is already preparing for their arrivals.

Norris and Buchholz agreed to one-year deals with Toronto on Thursday night, according to a source. The Blue Jays have yet to announce the contracts, and the agreements are pending physicals, which should be done by Monday at the latest.

Norris will be competing for a setup role in the bullpen, while Buchholz is expected to be in the mix for a starting job. That means there's a good chance either veteran Clayton Richard or rookie Ryan Borucki will find themselves without a spot in the rotation by the end of camp.

"He's a championship pitcher, professional starting pitcher, that I think any club would be fortunate to have," said Richard, who went 7-11 with a 5.33 ERA for San Diego last season. "We're excited to have him. I'm excited to have him as a teammate, and whenever you can add talent, that's going to help. It's a good thing."

The Blue Jays can't say too much on the record about either pitcher until the deals become official. General manager Ross Atkins will reserve his comments until after a press release announces the deals, and manager Charlie Montoyo was able to avoid questions from the Toronto media by attending a road split-squad game against the Braves on Friday, a 4-3 Blue Jays loss, instead of a home game vs. Pittsburgh, which ended in a 1-1 tie.

Assuming everyone is healthy by Opening Day, the Blue Jays will almost assuredly go with a rotation that includes Marcus Stroman, Aaron Sanchez and Matt Shoemaker. Buchholz becomes the favorite for the No. 4 spot, while the final job will go to either Richard or Borucki. Deciding which one has the best chance to win that spot depends on who you believe.

Borucki was long presumed to have a job on lockdown. The 24-year-old was Toronto's best pitcher during the second half of last season, and after he posted a 3.87 ERA over 97 2/3 innings, it seemed reasonable that he had nothing left to prove in the Minors. With options remaining on his deal, though, Toronto might decide to send him down anyway.

Atkins began the spring by listing Richard as a member of his rotation and stating Borucki would compete for a job. Does the latest signing change that stance? It might by the end of Spring Training, and that's one reason why Richard likely will need to have a good spring to hang onto his spot and avoid a demotion to the bullpen before the start of the year.

"Without a doubt," Richard said when asked if he welcomed the competition. "It's Major League Baseball, it's the best of the best. To shy away from something like that is sort of foolish. I think it's great. The better talent we have, the better off we will be as a team, and at the end of the day, that's what is most important."

The Blue Jays have undeniably added more depth to their pitching staff with the latest moves, and that's something that had to be done before Opening Day. Toronto was far too thin in the bullpen and had enough injury concerns in the rotation that some healthy big league pitchers will be welcomed into the clubhouse with open arms.

The news might be far less positive if it costs a promising pitcher like Borucki his job, but the Blue Jays aren't going to say too much on that until the deals are announced.

"I think they just offer leadership," Blue Jays bench coach Dave Hudgens said. "They have been through the wars. [Norris] and Buchholz have been in the league for a while. ... I think they will probably come in, feel themselves around a bit, get to know the guys, and I think they'll add a lot."
