KISSIMMEE, Fla. -- The Blue Jays headed to Osceola County Stadium on Sunday without a trio of players who were originally scheduled to make the two-hour trek to take on the Astros. Vernon Wells, Travis Snider and Rod Barajas all stayed behind to tend to minor injuries.

Toronto manager Cito Gaston said that Wells has been bothered by a sore left wrist -- the same one he fractured during a diving catch in Cleveland last May -- for much of the last week. Gaston noticed Wells favor his hand during his final at-bat in a game against Detroit on Saturday and Toronto's center fielder received a cortisone shot on Sunday morning.

"He said it's been bugging him the last few days," Gaston said. "But I thought the last at-bat might have done something. He swung at kind of a high pitch there and I saw him shake his wrist a little bit. So, we thought it'd be best to get it injected now and get that out of the way before the season starts."

Earlier this spring, Wells strained his left hamstring, which he originally injured last season as well. Wells has since recovered from that issue and has appeared in six Grapefruit League games as either the designated hitter or center fielder. Gaston said Wells will take two days off before likely playing against the Phillies on Tuesday night.

Snider -- Toronto's starting left fielder -- jarred his left knee during a catch at the wall during Saturday's game against the Tigers. The 21-year-old rookie tweaked the knee earlier this spring while running the bases in a contest against Philadelphia on March 18. Gaston said Snider has also been dealing with some back issues.

"He bumped into that fence yesterday out there, and that was a little sore on him," Gaston said. "So, we just left him back. Just a precaution. I hope it doesn't bug him down the line. We just didn't want to bring him over here. He's been bothered by his back this spring, too, so he hasn't made a lot of bus trips."

Barajas, who is the Blue Jays starting catcher, has also been fighting some back soreness, according to Gaston. Barajas has appeared in only six Grapefruit League games for Toronto due to missing time with Team Mexico for the World Baseball Classic. His last appearance came in a road game against the Pirates on Friday.

Gaston said he doesn't believe any of the injuries will warrant a trip to the disabled list for Wells, Snider or Barajas to begin the regular season.

"Hopefully, all these things are just minor things," Gaston said.
