Farrell quick hits: Brentz to start Friday

FORT MYERS, Fla. -- Quick hits from Red Sox manager John Farrell Thursday morning:

* Outfielder Bryce Brentz, whose self-inflicted gunshot wound in the leg cost him an invitation to his first big-league camp, will be summoned from the minors and start in right field against the Orioles on Friday. First baseman Travis Shaw, the 6-foot-4, 22-year-old son of former big-league pitcher Jeff Shaw who put up big numbers in Class A Salem last year (16 HRs, .305/.411/.545), also will make the trip to Sarasota, along with last year’s No. 1 pick, shortstop Deven Marrero.

* Farrell confirmed that left-hander Franklin Morales had his back checked in Boston, because he hasn’t shown the results they’d hoped for from the treatment he has been receiving for lower-back inflammation. He said he did not have a detailed update as of yet.

* With Craig Breslow making “very slow progress” from his shoulder discomfort, the Sox increasingly face the likelihood of having just one healthy lefty in the bullpen, Andrew Miller, when the season starts. Farrell noted that Koji Uehara has been particularly effective against left-handed batters, which will help in the absence of Breslow and Morales. Breslow was throwing from 90 feet today.

* Shortstop Stephen Drew is still displaying symptoms from last week’s concussion and will undergo more on-line testing today. Farrell had said they hoped Drew would have a workday today, but the ongoing symptoms eliminated that possibility.

* Clayton Mortensen is starting the split-squad game Friday in Sarasota, but Farrell said the club has no plans of stretching him out beyond three innings as a potential emergency starter. The sixth starter in camp right now is Alfredo Aceves, who will face the Rays on Saturday.

* Farrell cited the work of catchers Daniel Butler and Christian Vazquez as players who have made a strong impression in camp, and again noted the progress shortstop Jose Iglesias is making in his plate approach.

* And yes, Farrell saw the Terry Francona “Harlem Shake” video.

“We were talking about as players develop, he hasn’t developed anymore as a dancer," he said.

“I just hope it’s all a product of video, a product of technology, that none of that was real."

When will Farrell be shooting his video?

“Don’t blink," he said.
