"It's good," said Choo, who last played on March 15. "[Thursday], I did a full schedule of batting practice, shagging in the outfield, running. It was great, no problem. Today, I will do it again and if it feels real good, I think I will play [Saturday].
"In my career, I'm not hurt that much. The first time I felt it, I was worried about it. Twenty-four hours later, I felt great. It's not really a major injury. I feel a lot better now."
Reds manager Dusty Baker believed there was a good chance that Choo would play against the Rangers on Saturday.
"I have him penciled in," Baker said. "It depends on how he feels tonight after activity. I don't anticipate any setbacks."
In 11 games this spring, Choo is batting .400 (8-for-25). He fully expects to be in the lineup when the Reds open the regular season vs. the Angels on April 1.
"If I had this same feeling during the regular season, I could play," Choo said. "It's Spring Training and I still have a little more time. I don't want to make it worse. It's more important for the season. I want to play every day, 162 games."
