Loup helping to fill gap in Blue Jays' bullpen

TORONTO -- Rookie left-hander Aaron Loup has been exactly what the doctor ordered for the Blue Jays' ailing bullpen.

Toronto is currently without key relievers Sergio Santos, Jason Frasor and Luis Perez. While Frasor is expected back some time in August, both Santos and Perez are out for the season, which has left a gaping hole in middle relief.

Loup was one of several relievers to get promoted from the Minor Leagues for an audition. But unlike a lot of his fellow pitchers, the native of Louisiana has been able to seize the opportunity.

"He has gained some trust quickly," Blue Jays manager John Farrell said. "His mound presence is outstanding. Even when he gets behind in a 1-0 count, he has been able to locate down and away.

"I think more than anything, [it's] the air that he projects when he's on the mound -- in addition to quality stuff. We've thrown him right in, whether it was in New York or Boston, going up against [the Tigers] two days ago. He has done an outstanding job and he really has added a weapon for us."

Loup has allowed just three earned runs on five hits over 8 2/3 innings of work so far this season. He has also struck out four without issuing a walk while appearing in six games.

Those numbers compare favorably with what Loup was able to accomplish while pitching for Double-A New Hampshire. Loup posted a 2.78 ERA in 45 1/3 innings for the Fisher Cats this season en route to an appearance at the Double-A All-Star Game prior to his arrival in Toronto.

The most impressive aspect of Loup's tenure with the Blue Jays so far is that he hasn't been intimidated on the mound. While most rookies tend to arrive not fully trusting their stuff against Major League hitters, Loup has taken the opposite approach and has pitched aggressively.

"Every time our coordinators or our pro staff went through New Hampshire, each time they came back saying this guy shouldn't be overlooked," Farrell said.

"Sometimes the guys that don't receive all of the accolades are the ones that when they do get their opportunity [they take advantage of it] -- because they haven't been the high profile guy, they haven't received all of the accolades externally. He's unassuming, goes about his work. He has good stuff."

Ailing back sends Lind to disabled list

TORONTO -- The Blue Jays decided Monday that Adam Lind will require time on the 15-day disabled list.

Toronto's designated hitter, held out of the lineup for the third consecutive game on Sunday afternoon because of tightness in his back, was placed on the list retroactive to Thursday with what the Blue Jays called a mid-back strain.

First baseman David Cooper was recalled from Triple-A Las Vegas of the Pacific Coast League.

The injury is another setback in what has been a frustrating year for Lind. The 29-year-old spent more than a month at Triple-A after a disappointing start to the season, but had since begun to turn things around.

Cooper, 25, was recalled for the second time this season. He is batting .292 with two home runs and six RBIs in 24 games for Toronto. In Las Vegas, the left-handed hitter was batting .314 with 10 home runs, 52 RBIs and a team-leading 27 doubles.

Lind hit .288 with five home runs and 16 RBIs in 24 games since being recalled from the Minors, and had made a return to the heart of the Blue Jays' batting order.

"It showed some improvement [on Saturday], but still not to the point of getting back in the lineup," manager John Farrell said Sunday. "Given where we are right now, it's hard to go day to day with leaving just two guys on the bench."

Worth mentioning

• Right-hander Brandon Morrow was scheduled to throw two innings for Class-A Dunedin on Sunday in his first rehab start since suffering a strained left oblique muscle on June 12.

Morrow is expected to make a total of two starts for Dunedin before pitching an additional two games with Double-A New Hampshire. The goal by the end of the four outings is to have Morrow up to 85 pitches and ready for a possible return to the Blue Jays.

• Right fielder Jose Bautista was scheduled to swing a regular bat on Sunday for the first time since being placed on the 15-day disabled list earlier this month with a sprained left wrist.

Bautista took swings with a fungo bat on Saturday and followed that up by taking dry swings with a regular bat. It still appears unlikely that he will be ready to return by the time he is eligible to come off the DL on Aug. 1.
