Morrow said that the issue first came up on Wednesday and he immediately had Mirabello -- a team doctor based in Dunedin -- examine his arm. Morrow indicated that everything was fine, and he anticipates similar news on Sunday. The starter is optimistic that he will be able to take the mound for his next scheduled start on Wednesday.
"I think I'll be ready," Morrow said. "But I'm going to see the doctor tomorrow. That's just precautionary as well, just to pretty much write anything off."
As things stand, Morrow projects to be the No. 3 starter in Toronto's rotation, which will also likely include Shaun Marcum, Ricky Romero, Marc Rzepczynski and Brian Tallet. If Morrow's setback proves to be more serious and the righty needs to open the season on the disabled list, lefties Brett Cecil and Dana Eveland would be the front-runners for the fifth spot on the staff.

The 25-year-old Morrow does not believe a trip to the DL will be necessary.
"I just didn't want to turn what should be a two- or three-day setback into a two-week setback," Morrow said, "by going out there and really letting it get inflamed or whatever. I could've thrown through it [on Friday], is what I'm trying to say. I just wanted to back off and let it calm down a little bit. Better to do it now than in two weeks.
"Of course I would've rather have gone out there, but I think that they also appreciate the fact that I'm trying to be smart about it and trying to make sure that I'm ready for the opening series, and ready to go then rather than trying to pitch through stuff now."
Morrow -- acquired from the Mariners in a trade on Dec. 23 -- said he is not sure what initially caused the discomfort in his shoulder.
On March 10, Morrow threw 32 pitches over two innings in a "B" game against the Phillies. The right-hander then pitched on short rest, throwing 33 pitches in three innings during a start against the Braves on Sunday. He pulled himself out of his Friday start after the shoulder issue came up while warming up before the game in Kissimmee.
Morrow said the minor pain he felt on Friday was not as severe as it was following a bullpen session earlier in the week, though.
"I haven't had any problems all spring up until Wednesday, when it was the most sore it's been," Morrow said. "It was much worse on Wednesday than it was yesterday. ... I anticipate being able to go my next scheduled time out and everything will be fine."
