Liberatore, 27, has never pitched in the major leagues.
The left-hander appeared in two games for Triple-A Oklahoma City this season and allowed one run. It was the first run he’d allowed all season; in spring training Liberatore pitched in 11 games and did not allow a run in 10 ⅓ innings. He walked three batters, struck out nine, and limited opponents to a .118 batting average.
A native of Bellflower, Liberatore was acquired in the November 2014 trade that sent Jose Dominguez and Greg Harris to Tampa Bay.
Corcino has a 45-52 record with a 4.13 ERA in 168 career minor league games in the Reds’ organization. He appeared in five major league games last season and allowed nine runs in 18 ⅔ innings, a 4.34 earned-run average. He opened this season with Double-A Pensacola, tossing a scoreless inning of relief in his only outing.
The 24-year-old pitcher was signed by the Reds as a non-drafted free agent in 2008 from the Dominican Republic. He will report to Double-A Tulsa.
Dennick was claimed by the Dodgers from the Reds on Wednesday. The 28-year-old pitcher has a 27-31 record with 18 saves and a 3.88 ERA in 210 career minor league games over seven seasons. He appeared in eight games for the big-league Reds last season.
Corcino had been compared toJohnny Cueto coming up in the Reds’ organization. One scout who saw Corcino this spring clocked his fastball in the upper 80-mph range to go along with a plus changeup.
Dodgers pitcher Carlos Frias said he went to bed Tuesday night believing he would start for Triple-A Oklahoma City on Wednesday.
Frias learned Wednesday morning that he had been recalled to take the roster spot of pitcher David Huff, who was designated for assignment after Tuesday’s game. He flew from Oklahoma City to Los Angeles and did not arrive until 4:30 p.m. He wasn’t able to stretch with his teammates on the field.
