KANSAS CITY -- Blue Jays top prospect Brett Lawrie will be out of action for at least the next two-three weeks because of a non-displaced fracture in his left hand.
Lawrie suffered the injury when he was hit by a pitch during a game on May 31 while playing for Triple-A Las Vegas.
Initial X-rays did not reveal any fractures but when the swelling in his hand subsided a CAT scan discovered the damage.
"We took every precaution with every imaging available to us, so that we weren't overlooking something," Blue Jays manager John Farrell said. "The X-rays showed no fracture, he was X-rayed a second time, the bone scan showed no fractures, but yet the CAT scan did."
Lawrie was returned to the club's Minor League complex in Dunedin, Fla., to maintain his conditioning. He is not allowed to participate in any baseball-related activities for at least the next two weeks and likely won't return to Triple-A Las Vegas until the beginning of July.
The 21-year-old third baseman was hitting .354 with 15 home runs and 49 RBIs in 52 games this season. He also had 19 doubles and an impressive .415 on-base percentage while stealing 11 bases.
The latest development comes as a major blow to Lawrie, who was on the verge of being called up to big leagues at the time of his injury. General manager Alex Anthopoulous described the promotion as being "close" and it was expected he would debut in Baltimore on June 3.
"That's the one thing that is so uncontrollable, you just try to prepare the best you can through depth and other options," Farrell said. "This is unfortunate considering how close he is and yet this is a setback.
"He'll have to definitely get back into games once he is able to resume baseball activity and build back up to seeing live pitching again."
Escobar day-to-day with bruised quadriceps
KANSAS CITY -- Yunel Escobar was forced to miss Wednesday night's game because of a bruised left quadriceps muscle and is currently listed as day-to-day.
Escobar suffered the injury while attempting to steal second base during Tuesday night's game against Kansas City. He will be re-evaluated on Thursday but it is still unknown whether he will be able to play.
Mike McCoy got the start at shortstop, which left Toronto with Edwin Encarnacion as the only healthy body available off the bench. Escobar joins injured catcher J.P. Arencibia as reserves who would only be available in an emergency situation.
Blue Jays manager John Farrell said if something were to happen to McCoy during Escobar's absence, he would shift Jayson Nix to shortstop and bring Jose Bautista in from the outfield to play third base.
Juan Rivera then likely would take over in right with Encarnacion coming off the bench to play first base.
McCoy was also slotted into the leadoff spot of the batting order even though Rajai Davis has more experiece hitting in that position. Farrell said the decision was made because Davis has been successful in the bottom third of the lineup.
I feel like it gives us a lot more flexibility," Farrell said. "Rajai can take over an inning in that bottom third. It allows us to have our production spread out and I think more then anything he has felt comfortable. The numbers bear it out, he has been more productive down there."
Arencibia out of lineup with left thumb injury
KANSAS CITY -- J.P. Arencibia was held out of Wednesday night's lineup after re-aggravating a left thumb injury.
Arencibia originally dislocated his thumb during a game against the White Sox on May 28. He hurt it again on Tuesday night after being hit by a foul ball off the bat of Matt Treanor.
The 25-year-old was available to play on Wednesday in an emergency situation and is hopeful he will be ready for action in the series finale against Kansas City on Thursday.
"It's just one of those things that it's there both hitting and catching," Arencibia said. "No one is 100 percent the whole year, everyone plays with their bumps and bruises. So both sides of the plate I feel it, but it's not an excuse for affecting my play any bit."
The native of Miami will wear a protective cast on his thumb when he does return to action. It will be the first time Arencibia has taken that precaution and he said it's not ideal, but there isn't much of a choice if he wants to stay in the lineup.
"I hadn't been wearing it. I had just been going with tape because I really don't like to put too much stuff on my hands," Arencibia said. "Now it's at a point where I need to put it on so it doesn't re-aggravate it."
Arencibia is hitting .249 with 10 home runs and 32 RBIs in 46 games. He entered Wednesday ranked first among American League catchers in homers, second in RBIs, slugging (.509), OPS (.816), extra-base hits (20) and total bases (84).
Right-hander Jesse Litsch had a successful bullpen session in Dunedin, Fla. on Tuesday afternoon. It was the first time Litsch threw off a mound since being placed on the 15-day disabled list on May 20 with an impingement in his right shoulder.
Litsch is expected to throw two more bullpens before being placed into a simulated game situation. He then will begin a rehab assignment that likely will start at Class A Lansing.
Infielder John McDonald continues to make progress from a strained right hamstring, but will not be ready to play when he is eligible to come off the 15-day disabled list on June 12.
McDonald likely will get into a rehab game at the beginning of next week and is approximately 10 days away from a return to the Blue Jays' roster.
