Red Sox placed 3B Will Middlebrooks on the 15-day disabled list with lower back spasms.
Middlebrooks suffered the injury Wednesday and aggravated it Thursday. The Red Sox initially said he was day-to-day, but evidently they've decided the best course of action was to sit him down for a couple weeks. Jose Iglesias has been promoted to fill his spot on the roster and will share time with Pedro Ciriaco at the hot corner.
Red Sox placed OF Shane Victorino on the 15-day disabled list, retroactive to May 21, with a left hamstring strain.
Victorino ran sprints prior to Thursday's game, but evidently he still hasn't made enough progress. Given that he's also had a back issue lately, it's probably best to let him rest for a couple weeks. Daniel Nava will handle right field while Victorino is out.
Reds placed LHP Sean Marshall on the 15-day disabled list, retroactive to May 21, with a sprained left shoulder.
It's the second time this season that the shoulder has sent him to the DL, though the Reds called it tendinitis the first time around. The club figures to take it slowly with Marshall this time, so he could be looking at an extended absence. Manny Parra (pectoral) has been activated and will take Marshall's spot in the bullpen.
Giants general manager Brian Sabean said during a radio interview Thursday that he anticipates "there's some form of surgery coming" for Santiago Casilla (knee).
Casilla has dealt with a cyst on his right knee since last season and it recently became enough of an issue that he was placed on the DL. He shouldn't need a major operation, but it's not clear how long he would be sidelined.
Mariners designated INF Robert Andino for assignment.
The M's finally decided that they couldn't carry two no-hit middle infielder's, as Andino's .184/.253/.237 batting line is even worse than Brendan Ryan's. Andino is versatile, though, so it's possible he could drawn some interest on waivers.
Michael Pineda (shoulder) threw five innings Thursday in a start at extended spring training.
Pineda's fastball sat near 93 mph all afternoon and he reported no issues with his surgically-repaired shoulder. The right-hander is expected to make one more start at the Yankees' spring complex before heading out on a minor league rehab assignment. He should be stashed right now in leagues with big roster allotments.
Danny Duffy (elbow) will begin a rehab assignment with Double-A Northwest Arkansas on Sunday.
He'll throw 60 pitches for the Naturals. Making his way back from Tommy John surgery, Duffy will surely require the full 30 days on his rehab assignment. Assuming the results are there and his arm strength is back, he should be added to the Royals' rotation in late June. The left-hander is worth stashing on the DL if you have the roster space.
