"I feel really good, especially the last month," Rodriguez said via translator Tomas Vera. "Things have started coming how I planned it. I didn't have a good beginning of the season, but lately things have gotten better. The last few days, I've been doing really well."
Another roster move is coming when the Reds need a starting pitcher on Tuesday, but the switch-hitting Rodriguez adds another bat for the bench in the meantime.
"I'm left-handed strong. They [the Cardinals] called up another left-handed reliever [Kevin Siegrist]," Reds manager Dusty Baker said. "When you're facing a team that you really haven't scored on a lot, I'd pick up two bats if I could. … Pollo can hit. That's what he's here for. Hopefully he helps win a game or two in the meantime. He'll probably pinch-hit more than anything."
The Reds have two switch-hitters on the bench in Rodriguez and Derrick Robinson.
