Rockies backstop Wilin Rosario flashed some power in his brief big league debut last year. Looking to make his way back to "The Show" this spring, he showed some power Monday.

Rosario went 2-for-3 with a homer, four RBIs and a walk to lead the Rockies past the San Diego Padres, 11-2, on Monday as he continued to audition for the backup catching job on Colorado's Opening Day roster.

After flying out to right field in the third inning, the Rockies' No. 3 prospect plated Brandon Wood with a one-out single in the fifth. In the seventh, Rosario led off with a walk, scored on DJ LeMahieu's bases-loaded walk and later slugged a three-run homer off Alex Hinshaw as the Rox sent 11 men to the plate.

Rosario, signed as a non-drafted free agent prior to the 2006 season, is batting .333 with five RBIs in seven Cactus League outings. Jordan Pacheco, the other possible candidate to back up starting catcher Ramon Hernandez, is batting .400 in five Spring Training games.

"I talked to him about being the hitter, and us not seeing the big, large swing that we had seen over the course of the last couple of days," manager Jim Tracy told MLB.com on Friday. "I told him, 'You're a good hitter. Be that guy, let that thing happen, and don't try to force it.'"

A native of the Dominican Republic, 23-year-old Rosario was a mid- and postseason Texas League All-Star last year, as well as a Futures Game selection. He hammered 21 homers for Double-A Tulsa before earning a September callup to Coors Field.

In 16 Major League appearances, Rosario hit three homers, three doubles and a triple. He plated eight runs and batted .204.
