Rosario was recalled from Triple-A Albuquerque on Friday, Nick Groke of The Denver Post reports. It's still not clear where Rosario fits in, but he'll at least provide the Rockies with a powerful bat off the bench, and he's a nice alternative to Justin Morneau against left-handed pitching. With Colorado facing Dodgers southpaw Brett Anderson on Friday, it seems likely Rosario will start over Morneau at first base.
