TORONTO -- Travis Snider underwent an MRI on his right wrist in Las Vegas on Friday morning, but the results have not come back yet, according to Blue Jays manager John Farrell.

Snider jammed his wrist diving for a ball in the third inning of a Triple-A game Thursday night and exited the contest immediately after.

The 24-year-old was off to a fast start with the Las Vegas 51s in the Pacific Coast League after losing out on Toronto's starting left fielder's job to Eric Thames in Spring Training.

Snider, a 2006 first-round Draft pick, entered Thursday night's contest riding an 18-game hitting streak, but went 0-for-1 in two plate appearances.

"He's driving the ball to all fields," Farrell said of Snider, who is batting .400 through 19 games. "He's been in a good place offensively. He hasn't been so pull-oriented, his instincts on the basepaths have been consistent with what we've seen and his defense has been solid. Offensively, he's been using the whole field."

Entering Friday's game, Snider ranked in the PCL's top five in batting average, on-base and slugging percentage, OPS, doubles and total bases, while leading the league with 23 RBIs. He has also added four homers and two stolen bases, while walking 11 times.

Despite Snider's strong month, Farrell reiterated that Thames is Toronto's starting left fielder, although he said the club is always evaluating its options.

Although Snider remains behind Thames on the depth chart and has been up and down between the Minors and Majors for much of his career, Farrell still has high regard for the Kirkland, Wash., native.

"He's a talented guy, we like him a lot," Farrell said. "He's going to have a very good Major League career."

Snider has appeared in 232 games since making his Major League debut at Yankee Stadium in 2008, but has never played more than 82 games in a season.

Farrell won't consider starting role for Perez

TORONTO -- Luis Perez was handed the loss after surrendering four runs in the 10th inning of Friday night's contest against the Mariners, but the left-hander has emerged as one of the Blue Jays' most steady relievers.

Entering Friday's contest against the Mariners, the 27-year-old has thrown the most innings in the Majors by a reliever without allowing a run and ranks fourth in the American League in WHIP among relief pitchers who have thrown at least 10 innings.

Perez's dominance has prompted many to ask manager John Farrell if the lefty would get a look in the rotation should any injuries occur, but Farrell says he would prefer to leave him in his current role.

"Because he hasn't been stretched out, we would go to others first," Farrell said of Perez, who started four games with the Blue Jays in 2011. "Then if opportunities came to stretch him out, then that would be plan B.

"At this point, we haven't put him on the depth chart in that role [starting]. He's become such a valuable member of the bullpen, I'd hate to take away from one strength when we might have other options that might be equal to him in the rotation."

According to Farrell, those options include Jesse Chavez and Joel Carreno, who are starting at Triple-A Las Vegas, and Chad Jenkins who is at Double-A New Hampshire.

Complicating a potential switch to the rotation for Perez is that he's out of options, meaning Toronto would risk losing him through waivers if the club sent him to the Minors to get some starts under his belt.

Perhaps the biggest reason Farrell wants Perez to continue working out of the bullpen is that he can log multiple innings and is not just a situational lefty.

"He has adjusted as his outings and experience have grown," Farrell said. "The use of his changeup, he's tightened up his breaking ball, he pitches with an awful lot of confidence. It gives him the ability to attack lefties and righties with equal efficiency. He has really evolved into a good left-handed reliever.

"He's extremely valuable to us in the role he's in."

The Dominican native has held both right-handers and left-handers to below a .160 batting average and a sub-.400 OPS and is tied with three others for the second-most strikeouts in the AL among all relievers with 14.

Hutchison shows progress in second start

TORONTO -- Drew Hutchison walked away with a no-decision Thursday night in his second career start, but Blue Jays manager John Farrell believes he showed definite signs of improvement.

The 21-year-old located his pitches better than in his Major League debut and Farrell believes there are specific reasons for that.

"I thought he was down in the zone more consistently," Farrell said about Hutchison, who walked one after issuing three free passes in his first outing. "I thought he had more depth to his slider and his four-seam at times was used a little bit more frequently. He created some run with his two-seamer ... he's doing fine right now."

After right-hander Dustin McGowan experienced another setback and will be shut down for at least another two weeks, Hutchison will likely get an extended look in the rotation.

Hutchison, Toronto's No. 7 ranked prospect entering the season according to MLB.com, will take a 1-0 record and 6.10 ERA into his next start against the Rangers.

Worth noting

• Blue Jays manager John Farrell announced prior to Friday's game that closer Sergio Santos was rehabbing his right shoulder in California and will join the team when it goes on its West Coast trip starting May 3 in Los Angeles.

• The Blue Jays are offering a peanut controlled zone at three home games this season at Rogers Centre: May 28 against the Orioles, July 24 against the Athletics and Aug. 10 against the Yankees. On those dates, peanuts and other nuts will not be allowed in the area.

Tickets are reserved for individuals with peanut and other nut allergies and their families and friends only. They will be seated in a section of the 200 level outfield seats in right field.
