"It's going to be a little weird, but it's something that I'm ready for," Cordero said of facing his old team. "When they say my name in the bullpen, I'm going to have to be ready to come into the game and try to do my job."
The Astros are the sixth team for the 37-year-old Cordero, who saved 150 games in his four years with the Reds from 2008-11. He signed as a free agent with the Blue Jays prior to this season before getting traded back to the National League.
"[The Reds] have some new faces, but most of those guys were there when I was there," he said. "I can do my own scouting report and go with it and try to get them out because they have some good hitters. They're a good-hitting team and are dangerous. You have to be careful when you're facing those guys."
