"I was ready. I'll be ready," Cairo said.
Cairo retired as a player following last season, capping a 17-year career in the big leagues. On Feb. 14, he joined the Reds' baseball-operations department as a special assistant to general manager Walt Jocketty. But plans changed upon Berry's throat cancer diagnosis in March, and Cairo has gotten a lot of coaching exposure in a jiffy.
"It's been a learning experience," Cairo said. "I've got Dusty and the rest of the coaches with a lot of experience. I'm right besides Dusty. He's got a lot of experience. His job is a handful and he knows how to deal with it. This has been an opportunity to learn."
Like most coaches, Cairo has a fungo bat at his side nearly constantly and has recently started throwing batting practice.
"I wasn't planning on this, but they asked me to help," he said. "Walt brought me over here to work with him, and I couldn't say no. It's a great opportunity for me."
Cairo, who has played for managers like Baker, Joe Torre and Tony La Russa, could one day be a skipper himself. That's not at the forefront at the moment, however.
"Right now, I'm just trying to help," Cairo said. "Later on, maybe. I want to help with the players and be helpful for the team."
