Phillies place Ruiz on 15-day DL

Catcher strains oblique in Friday's loss; Marson recalled

DENVER -- Carlos Ruiz tried to play through the pain Friday, but it finally became too much.

The Phillies catcher strained his right oblique in the third inning of Friday's 10-3 loss to the Rockies at Coors Field, but he played until the seventh inning. The injury is serious enough that the Phillies placed Ruiz on the 15-day disabled list Saturday and recalled catcher Lou Marson from Triple-A Lehigh Valley to take his place on the roster.

"I know it's early in the season and we have a lot of games left, but I don't want to be on the DL," Ruiz said. "But there's nothing I can do. I have no control over that."

Ruiz is eligible to return to action April 26, but Phillies general manager Ruben Amaro Jr. could not say if Ruiz would be ready by then. Amaro said he should know more after Ruiz has an MRI exam on Monday in Philadelphia.

In the meantime, Chris Coste and Marson will share time behind the plate.

Coste was in the starting lineup Saturday, and he figures to get the majority of playing time between the two, although Manuel said Marson will play.

"Unless Coste wants to -- he can get in there tonight and take off," Manuel said. "I won't hold him back. If he hits and we play good and everything ... I'll play Marson some, but I don't know what I'm going to do."

Manuel has said in the past that Coste is more effective when he plays only a few times a week. Obviously, with Ruiz out, Coste has the opportunity to play much more.

"I have no idea," said Coste when asked what was the best amount of playing time for him. "For me, it's always a mystery. I have no problem playing a lot. I have no problem playing two times a week. Charlie has never made it a secret that when you do well when you get the opportunity, you'll get more playing time."

Marson is hoping to gain a little experience, too. He was called up last September, but played in just one game.

"I feel like I've had some good at-bats," Marson said. "With regular at-bats, I feel like I will be successful."
