The Rockies have sent third baseman Nolan Arenado to the minor leagues, MLB.com reports.
Arenado is the Rockies' top prospect and is expected to reach the majors this season. He hit .288/.288/.596 in 52 plate appearances this spring. He will start the season at Triple-A Colorado Springs, and if he hits well, he'll have a shot at displacing Chris Nelson and Jordan Pacheco as the third baseman in Denver.
