Culberson remains sidelined with back issue

SCOTTSDALE, Ariz. -- The Rockies are keeping a close eye on the back issue that has rendered infielder Charlie Culberson inactive since March 8. Culberson was 4-for-11 (.364) before the injury.

Culberson batted .293 in 47 games during a 2013 callup. Last year, however, he hit .195 in 95 games, and there were suspicions that he wasn't fully healthy.

"We know how difficult backs can be, so I'm sure he'll have a different routine every day than he's had in the past just to stay out in front of this thing," Rockies manager Walt Weiss said.

In other health-related developments:

• Lefty starter Jorge De La Rosa, who missed two starts with left groin tightness but threw two scoreless innings in a "B" game on Sunday, has bounced back to the club's satisfaction. He was scheduled for a side session on Monday.

• Infielder Daniel Descalso, scratched from Sunday's game with a right oblique strain, felt better Monday but was not in the lineup.

• Non-roster infielder Omar Quintanilla hasn't played since March 7 because of right forearm tightness, but he has begun throwing.

• Non-roster outfielder Roger Bernadina was still a few days from getting a bat in his hand because of a wrist injury he suffered in an on-field collision on March 7.
