TORONTO -- Sergio Santos will miss the rest of the season after the Blue Jays announced on Sunday morning that he will undergo right shoulder surgery in the very near future.
Santos, who has been out since April 21, had been attempting to rehab the injury at the Blue Jays' Minor League complex in Dunedin, Fla. The initial goal was to avoid surgery, but the discomfort didn't subside and he will be forced to go under the knife.
The 29-year-old Santos received the diagnosis after throwing a bullpen session on Saturday and experiencing pain as his level of intensity increased.
"It will be focused around the labrum," Blue Jays manager John Farrell said of the surgery. "Rotator cuff seems to be fine, in tact, completely healthy based on all the MRIs and exams and tests that he has gone through."
Santos began the season as the Blue Jays' closer, but managed to appear in just six games before being placed on the 15-day disabled list. He was acquired during the offseason from the White Sox for pitching prospect Nestor Molina.
Farrell was quick to dismiss any notion that his club received damaged goods in the deal and said Santos didn't experience any issues until his final outing on April 20 in Kansas City.
The Blue Jays are currently in the process of scheduling surgery with Dr. Lewis Yocum. The extent of the injury and rehab won't be known until after the procedure is complete, but the club remains optimistic he will be ready for Spring Training.
"The recovery time was taking longer than normal, so that's initially when we backed him down to address some strengthening issues, or take the approach of rehab and strengthening," Farrell said.
"As he got back through his throwing program, flat ground and long toss -- he felt good in that regard -- but when he gets on the mound with that increased intensity, that's where he feels the discomfort. So that's where the surgery is the next step."
Santos' first season in Toronto officially comes to an end after posting two saves in four opportunities and a 9.00 ERA. He remains under club control through 2017 and has a $9.75 million guaranteed contract with the possibility of earning $29.25 million over that span.
Labrum injuries are often very difficult for pitchers to overcome. Current Blue Jays closer Casey Janssen underwent surgery to repair a torn labrum in 2008 and was forced to miss the entire season. Even when he came back in 2009, he didn't have his typical effectiveness.
It wasn't until he was two years removed from the procedure that Janssen felt he regained his previous form.
"The comeback year is tough," said Janssen, who is a perfect 13-for-13 in save opportunities since taking over the closer's role. "At times, you might show your velocity, but the life and the sharpness wasn't there until that next one.
"Hopefully, that's not the case with Sergio. He has an electric fastball, so he if puts up the velocity number, I'm sure he can get by with not his best stuff."
Slumping Davis gets rare off-day
TORONTO -- Left fielder Rajai Davis received a rare day off on Sunday as he attempts to work through his recent struggles at the plate.
Davis entered play on Sunday mired in an 0-for-23 hitless stretch. That prompted manager John Farrell to leave him out of the staring lineup in order to get an additional day of rest prior to a six-game road trip.
"At times, he has chased some pitches," said Farrell, who inserted Ben Francisco into the starting lineup. "Prior to this recent stretch, when he has gotten pitches around the plate, he hasn't missed them. There have been a couple of at-bats of late where he has gotten his pitch and fouled it straight back or rolled into a double play.
"There are times where he has missed the pitch he has gotten, so he is due for a little bit of a break."
Davis took over the starting duties in left field during late May after Eric Thames was optioned to the Minor Leagues following a disappointing start to the year.
The 31-year-old Davis responded well and saw his average peak on June 24 at .282. The production has dropped during the recent skid and he is now batting .243 with four homers and 23 RBIs.
• Right-hander Brandon Morrow felt fine after his last bullpen session and is scheduled to throw again on Monday. He is expected to throw two more bullpens before being allowed to face live hitters. Morrow has been out since June 12 with a strained left oblique muscle.
• Right-hander Drew Carpenter will become the Blue Jays' main option in long relief following the departure of Jesse Chavez to the Minor Leagues. Carpenter has appeared in two games with the Blue Jays this season and has allowed two runs.
