Nelson has dealt with inflammation in his left wrist since April 25, when he injured it in Pittsburgh while diving to make a play. The injury did not immediately improve, and the Rockies placed Nelson on the 15-day disabled list Wednesday, retroactive to May 15.
"You don't want to be on the disabled list," Nelson said last week. "It's nothing you want to be proud of.
"But at the same time, I'm not really helping my team or helping myself. I just need to get it back healthy. Especially hitting with my wrist, and diving and all that good stuff, this is a learning experience."
Nelson is eligible for reinstatement on May 31, and manager Jim Tracy doesn't anticipate Nelson being out longer than that. Tracy said the third baseman will join the club's Triple-A affiliate, the Colorado Springs Sky Sox, this week while they host the Oklahoma City RedHawks.
"I don't have the schedule in front of me, but he is going to play with the Triple-A club within the next day or so and begin his rehab," Tracy said.
Nelson had a history of various injuries during his Minor League career, and often received criticism for repeated injuries. Before landing on the DL, Nelson was hitting .219 with five doubles and seven RBIs in 24 games for the Rockies, including 20 starts at third base.
