Brennan (shoulder) threw a bullpen session Friday, Greg Johns of MLB.com reports. Brennan was placed on the 10-day injured list Aug. 15 due to right shoulder inflammation, but he's been cleared to resume throwing and is set to hurl another side session Monday. The Mariners have yet to establish a firm timetable for his return.
The Mariners placed Brennan on the 10-day injured list Thursday due to right shoulder inflammation. Brennan downplayed the arm injury after experiencing some discomfort during his relief appearance Tuesday against the Padres, but the Seattle training staff evidently felt differently about the matter after re-evaluating the rookie reliever. Based on the description of the injury, Brennan doesn't appear to be dealing with a significant concern, but he'll be shut down for at least a week and a half in any event. Seattle called up Taylor Guilbeau from Triple-A Tacoma in a corresponding move.
Brennan reported being completely pain-free Wednesday after having exited Tuesday's appearance versus the Padres with arm discomfort, Greg Johns of MLB.com reports. "There's zero pain and I passed all the strength tests," Brennan said. "As the season goes on, it's more of a fatigue factor in your arm. I was maybe a little more tired than normal arm-wise, so it was kind of dragging. But today I played catch and the ball came out really good." The right-hander was able to play light catch prior to Wednesday's game and came out of it no worse for wear. Brennan felt the fact he made twice as many warmup throws as usual before coming into Tuesday's contest led to the fatigue he felt, and it remains to be seen if the Mariners will opt to let him rest the arm for a few days or return him to the injured list in order to sign another reliever.
Brennan, who was removed from Tuesday's appearance against the Tigers after two pitches with an arm injury, checked out OK after the game but will still be reevaluated Wednesday, Greg Johns of MLB.com reports. Brennan just recently came off the injured list with a shoulder issue, and he'd logged just two appearances since returning prior to Tuesday's outing. The right-handed reliever apparently looked out of sorts from his bullpen warmup session according to Mariners manager Scott Servais. "It was kind of the perfect storm," Servais said. "He worked out his upper body today, then was out in the bullpen and threw too many pitches. We had the extended inning there, so when he came in, you could kind of tell from the first couple of warm-up pitches he wasn't right."
Brennan exited Tuesday's win over the Tigers with an apparent arm injury, Greg Johns of MLB.com reports. Brennan threw only two pitches before leaving the game with what looked to be a right arm injury. The 28-year-old was recently sidelined with a shoulder injury, but the specifics of his current injury remains unclear.
