SCOTTSDALE, Ariz. -- Reds center fielder and leadoff hitter Shin-Soo Choo still wasn't ready to return from back spasms on Monday. Chris Heisey started in his place vs. the Rockies.
Choo has not played since Friday and was scratched Saturday when his back started hurting.
"He's day to day," Reds manager Dusty Baker said. "He's getting better. He's not playing [Tuesday]. Then we have a day off [Wednesday] and we'll check and see after the off-day."
Choo is batting .400 (10-for-25) in 11 spring games and has seven hits in his last 11 at-bats.
"I'm not worried," Baker said. "He was playing awfully good before he got hurt. I just hope he can pick it back up where he left off."
