Cuddyer hits DL with hamstring injury

Outfielder improving, but shelved for third time this season

DENVER -- Two days ago, right fielder Michael Cuddyer was adamant about not going on the disabled list with a sore left hamstring and said, "You can put that in bold letters." On Sunday, after he was placed on the disabled list, Cuddyer said, "Foot in mouth, right?"

The Rockies had to clear a spot on their active and 40-man rosters for Christian Bergman, who came off the 60-day disabled list to start Sunday. Right fielder Carlos Gonzalez, who underwent season-ending surgery Aug. 18 to relieve the patellar tendinitis in his left knee, was placed on the 60-day disabled list to make room on the 40-man roster for Bergman. And Cuddyer was placed on the disabled list for the third time this season.

"No question, I'm getting better," Cuddyer said. "But with everybody sore that can do more than me, I'm the low man on that totem pole. I'm just the most limited of everybody. And unfortunately, I'm the guy that has to be sacrificed for the roster spot."

Cuddyer will travel with the Rockies on their seven-game road trip that begins Monday at San Francisco but is not eligible to be activated until Sept. 8.

"It wasn't an easy move to make, because I feel he's probably a few days away [from returning]," manager Walt Weiss said. "He's fought so hard to get back on the field. It's been a tough year for him physically. I didn't want to have to make that move. But our bench is beat up. Obviously our bullpen is pretty taxed right now. It's going to be tough to survive even a few days as short-handed as we are right now, so we had to make that move."

The move could have been made retroactive to Monday, but in the Rockies' 5-4 win in 13 innings on Saturday, Cuddyer pinch-hit and walked in the 12th inning and was then lifted for a pinch-runner.

Catcher Wilin Rosario was unable to hit Saturday due to a sore left wrist, and Weiss said he didn't want to use first baseman-outfielder-catcher Matt McBride because he "was our multi-purpose guy," whom Weiss wanted to keep on the bench if the game went extremely long.

Had that happened, Weiss said he would have been "strapped" with Cuddyer on the bench. But Weiss said when he sent Cuddyer up to pinch-hit, he didn't think Cuddyer would have to go on the disabled list Sunday.

Cuddyer, 35, will be a free agent after this season, the final one of his three-year, $31.5 million contract. He has played in 34 games and is hitting .331 with six homers and 19 RBIs. This season, he missed 25 games due to a left hamstring strain -- that injury was behind the knee, unlike this one is in the upper area of the hamstring -- and then missed 60 games with a fractured left shoulder socket.

"What I love to do is play the game," Cuddyer said. "Obviously this year has been rough. You feel like you're not living up to your end of the bargain. It's not by choice, obviously. Physically things have been rough this year -- one thing after another."
