Dolsi had been resting since Monday with what head athletic trainer Kevin Rand called fatigue in his right shoulder. According to manager Jim Leyland, the rookie right-hander aired out his arm in a practice session with Rand on Thursday and felt fine.
Dolsi said he felt healthy again Friday after an afternoon side session.
"I feel good, ready to go," Dolsi said.
Asked if Dolsi could be used in relief Friday, Leyland said, "I would hope so."
Monday was Dolsi's fourth outing in five days. He had pitched in three consecutive games during the Tigers' four-game series at Baltimore, the last of them a 10th-inning appearance that Leyland was hoping to avoid, but was forced into once the game went into extra innings with Detroit's bullpen depleted.
None of those appearances were particularly long; Dolsi threw a total of just 16 pitches over the three outings. However, he ran into problems in his second inning of work on Monday at Kansas City after sitting through Detroit's 10-run rally in the eighth inning.
Dolsi ended up with four runs allowed on four hits in an inning-plus, throwing just 11 of his 24 pitches for strikes and inducing no swings and misses. He has given up seven runs on 10 hits in six innings over his past six outings, walking five and striking out none. In the process, his ERA has risen to 4.85 for the season, while his walks total (16) has surpassed his strikeouts (13).
"He's going through a stretch where it's showing his inexperience," Leyland said Friday. "He'll be fine. It's been a good time to break him in. I'll use him tonight, long if I need to. It's been good for him to go out there and get some more innings under his belt, but it's caught up with him a little bit."
Even so, Leyland calls it a good experience for him, referring to him as a "good project."
"He's what I call a very healthy project," Leyland said. "I like him a lot. I'm very impressed with him. He has very good equipment."
