Detroit Tigers right-hander Beau Brieske reached 97 mph with his fastball on Friday in his second rehab start for Triple-A Toledo.
The 24-year-old, who hasn't pitched in the majors since July 12 and is on the injured list with right forearm soreness, had a pain-free outing. He felt healthy Saturday, too. The positive reports put him on track to pitch Thursday for the Tigers against the Cleveland Guardians at Comerica Park.
Then, Brieske revealed a setback: right bicep tendinitis.
"He went to his bullpen and told (Doug Bochtler, Triple-A pitching coach) that he needed to shut it down while it was sore," manager A.
