Before shortstop Jose Reyes returns to the Rockies' roster — if he returns — the club is already juggling spots in the infield.
Colorado on Friday activated utilityman Daniel Descalso to make his season debut. To make room for him, the Rockies optioned first baseman Ben Paulsen to Triple-A Albuquerque.
Descalso missed more than a month after breaking his left hand in spring training, when he was hit by a pitch from Cleveland's Tom Gorzelanny in a Cactus League game.
The veteran shortstop will fill a backup infield role, including at first base, manager Walt Weiss said.
