Betancourt progressing, but return date uncertain

DENVER -- It's still not clear how long it will be before reliever Rafael Betancourt rejoins the Rockies' bullpen as he recovers from a groin injury.

Betancourt is eligible to come off the 15-day disabled list Sunday, but said Friday he planned to throw a light bullpen session that day and again Sunday. He also said he will start to face hitters on Colorado's upcoming seven-game road trip.

"I don't know exactly when he's going to be back with us, but he's doing well," Rockies manager Walt Weiss said. "There's been no setbacks, he was progressing nicely and passing all his tests until now. We're just going to continue to move forward."
