Chris Nelson (wrist) went 0-for-3 Monday in his first rehab game with Triple-A Colorado Springs. "I did hear he put two balls in play," Rockies manager Jim Tracy said. "He had two really good swings and put two balls in play very hard. Didn't necessarily get any results from it, but did OK from what I understand for the first day back." Nelson is eligible to return from the disabled list on May 31, and he'll probably be ready then if he doesn't have a setback.
