Rox rest Torrealba's tight hamstring

Catcher to sit Sunday, too, but should return for playoffs

LOS ANGELES -- The Rockies' quest for a National League West title took a hit prior to Saturday's game, when catcher Yorvit Torrealba was held out with a tight hamstring and reliever Josh Fogg remained in the team hotel with the flu.

Rockies manager Jim Tracy said third baseman Ian Stewart and outfielder Dexter Fowler also seemed to be battling flu symptoms, both feeling "punky."

Torrealba had 17 RBIs in September and has helped fuel the Rockies' stretch drive. He is not scheduled to play Sunday, either, though Tracy said he would be fine for the postseason.

"There's no strain, there's no pull, there's nothing like that," Tracy said. "It's a tight hamstring that we want to loosen up.

"It's the right thing to do. We're going to do everything we can do to win the division, but do it sensibly."

Tracy said he became concerned about Torrealba's leg the way he ran out his first-inning double on Friday. He met with his medical staff and then Torrealba, deciding to play it safe.

"I don't think it's a very good idea to push the envelope and him ending up not being able to play next week," he said.

Chris Iannetta started at catcher Saturday, batting sixth.

Fogg remained at the hotel in the team's effort to prevent the virus from further spreading throughout the clubhouse. Director of clubhouse operations Keith Schulz also stayed at the hotel with the flu.
