Cingrani -- a left-handed starter who split this season at Class A Bakersfield and Double-A Pensacola, and ranked by MLB.com as the Reds' No. 3 prospect -- threw 146 innings in the Minors and is near his innings limit.
"We didn't bring him up here to be a starter," Reds pitching coach Bryan Price said on Wednesday. "We didn't bring him up here to be a guy who inherits a lot of innings during his stay. We certainly feel, for a guy who is an experienced relief pitcher and being short from that side, that he could give us some support in a more limited role."
Cingrani has experience as a closer from his season at Rice University. As for whether he would get consideration for the postseason roster, Price declined to say.
"I don't think it's something I should talk about," Price said. "I'll let Dusty [Baker] talk about it."
