"It was great," Reds manager Bryan Price said. "It was something that was fun to watch at the end of a game where there wasn't a whole lot going on. He came in and threw strikes, which was great to see. He had a real nice breaking ball, got a couple of strikeouts and ended up pitching a nice inning for us."
Corcino threw 10 pitches, with eight strikes. His first batter, Welington Castillo, went down on three pitches -- with strike three coming on a breaking ball. Chris Valaika followed with a strikeout before Chris Coghlan flied out to left field.
Reds fans gave a nice ovation to Corcino, who tipped his cap in appreciation. He received handshakes from Price and his teammates inside the dugout.
"Everybody was so excited to see me and tell me congratulations and happy birthday," Corcino said. "They're very happy with me, and I'm happy with them because they gave me the opportunity."
Corcino, ranked as the No. 11 Reds prospect by MLB.com, is a developing starting pitcher but was called up Friday from Double-A Pensacola to help a taxed bullpen.
Since he's been with the club, his fiancée and 11-month-old son, Kaden, have been on hand to watch for when he might appear. At his home in the Dominican Republic, family awaited the news. The first strikeout will especially be a fond memory of a nice debut.
"It's unbelievable. I was so excited," Corcino said. "My family is back home in the Dominican. My son was here watching. I'm so excited I have that ball for him."
