Blue Jays option Laffey to Triple-A Las Vegas

TORONTO -- The Blue Jays optioned left-hander Aaron Laffey to Triple-A Las Vegas following Wednesday's 4-1 victory over the Orioles.

Laffey had been promoted to the Major Leagues on Monday to provide depth to an overtaxed bullpen, but he did not appear in a game. The veteran has had two stints in Toronto this season but has yet to throw a pitch.

Toronto did not announce a corresponding roster move but indicated that one is expected prior to Friday night's series opener against Boston. The transaction likely will involve a position player, as the Blue Jays anticipate going back to a seven-man bullpen.

The 27-year-old Laffey is 21-23 with a 4.34 ERA in parts of five big league seasons. He has spent time with the Indians, Mariners and Yankees, but will now find himself back with Las Vegas to provide organizational depth.

Snider suffers another setback with right wrist

TORONTO -- Outfielder Travis Snider, whose injured right wrist has kept him out of action for most of May, has yet to make any significant progress.

Snider, who is on Triple-A Las Vegas' seven-day disabled list, was recently sent to the club's Minor League complex in Dunedin, Fla., to continue his rehab.

There is no immediate timetable for when he might be able to return, and there are several obstacles he must overcome before he gets back onto the field.

"He's continuing to receive treatment," manager John Farrell said. "There has really been no advancing of a hitting progression of any kind. The updates that I have [say] that he's continuing to receive treatment to let all the symptoms that he was experiencing when he tried to come back be resolved in its entirety."

Snider sustained the injury while attempting to make a diving catch with the 51s on April 26. He was listed as day to day but eventually had to be placed on the seven-day DL after the wrist failed to improve as expected.

The 24-year-old returned to action on May 9, but the symptoms did not go away. He proceeded to record just one hit in six games before being shut down for a second time.

The club then decided to send Snider to the Bobby Mattick Training Center to continue his rehab.

"[We] felt like it was going to be a seven-day DL situation that would have him back on the field, but when it recurred and there was no clear-cut return date, as we've done with most of our players, [we got him] back to our rehab center in Dunedin," Farrell said.

The injury woes could not have come at a worse time for Snider, who could have been in line for a promotion to the big leagues after left fielder Eric Thames was optioned to Las Vegas.

Thames was instead replaced by fourth outfielder Rajai Davis, and Snider will have to get healthy and regain his stroke at the plate before the Blue Jays contemplate any significant changes to the roster.

Snider is hitting .333 with five home runs and 27 RBIs in 26 games with Las Vegas this season. He is a career .248 hitter over parts of four seasons in the Major Leagues.

Johnson gets day off; Escobar good to go

TORONTO -- Kelly Johnson was held out of the lineup on Wednesday night against Baltimore as the Blue Jays continue to monitor his injured right leg.

Johnson has been dealing with soreness in his hamstring for the past several weeks and had to miss Saturday's and Sunday's games in Texas because of the lingering discomfort.

The 30-year-old veteran returned for the first two games against Baltimore, and according to manager John Farrell, an off-day on Wednesday was always part of the plan.

"[It's] not a flareup," Farrell said. "Upon his return, it was almost a planned usage to take advantage of the day off tomorrow to give him two full days -- just to obviously keep him active but yet at the same time, take advantage of when extended rest can be had."

Johnson received a cortisone injection last Friday night, and although his condition improved enough for him to get back into the lineup on Monday and Tuesday, he was still in noticeable discomfort.

Farrell doesn't believe that Johnson's injury will get worse if he plays, but it is a situation the club will have to monitor in the coming days and weeks.

"Any time we have a chance to take a little bit more rest to try and get ahead of it while in season without missing him for two full weeks, that's our approach at this point," Farrell said.

In other injury news, shortstop Yunel Escobar has been cleared for action despite the fact that he is dealing with a sore left groin. Escobar had to leave Sunday's game in Texas after the fourth inning and missed Monday's series opener against Baltimore on Monday, though he returned on Tuesday night.

Escobar, who had an RBI in that game, came away without any symptoms and should now be ready for everyday action.

"He's pretty much good to go," Farrell said of Escobar, who entered play on Wednesday hitting .255. "If he's pressed on a first-to-third situation or if there's a movement that might stress the groin, we'll certainly monitor, but he came out last night OK."
