SCOTTSDALE, Ariz. -- The Rockies optioned infielder Charlie Culberson to the Minors and traded Minor League catcher Audry Perez to the Orioles for cash considerations on Tuesday in a pair of roster-clearing moves.
Culberson, 25, batted .195 as a utility player last year after hitting .293 in 47 games in 2013. The Rockies saw a more prepared Culberson early in camp, but he suffered a bulging disk in his lower back and didn't play in Cactus League games from March 8-28.
Since the Rockies signed former Cardinals utilityman Daniel Descalso during the offseason, Culberson was vying to forge a spot for himself.
"If he was an older guy that was in a platoon guy, late in his career, it's a different story," Rockies manager Walt Weiss said. "But he's still a young guy, and we feel there is some development ahead of him. We still really like the talent."
The Rockies signed Perez, 26, to a Minor League contract this winter after he had appeared in three games for the Cardinals in 2013 and '14. The Rockies had reassigned Perez to Minor League camp on March 22.
