CINCINNATI -- For the second time in a week, Reds center fielder Drew Stubbs was out of the starting lineup. Dave Sappelt started for Stubbs in center field, like he also did Tuesday at Chicago.

"He looked a little worn [down Sunday]," Reds manager Dusty Baker said of Stubbs. "You could sort of see his bat dragging and his total demeanor sort of dragging. I decided to give him a day off today after what I've seen the last couple of days. Plus that light air in Colorado didn't help either if you're dragging some."

Stubbs entered Monday batting .249 with 15 home runs, 42 RBIs and a .324 on-base percentage while appearing in 145 of the Reds' 146 games. While he's trying to avoid 200 strikeouts -- he's currently at 188 -- Stubbs has 37 stolen bases and 89 runs scored.

"I figured he can get fresh again and steal some more bases and hopefully get 100 runs," Baker said.

Valaika tears ACL, hopes to be ready by spring

CINCINNATI -- It's never a welcomed sight in a clubhouse. There was Reds infielder Chris Valaika, standing at his locker Monday with the aid of the dreaded crutches and knowing that his season was prematurely over.

Valaika sustained a completely torn anterior cruciate ligament (ACL) in his right knee and will have surgery next week with the expectation of being ready in time for Spring Training 2012. The injury happened as the 26-year-old swung for a single in the top of the fifth inning vs. the Rockies on Sunday. He remained in the game before exiting with two outs in the bottom of the fifth.

"I swung and my spikes got caught. I just twisted on it," Valaika said. "I tried to play through it, I wasn't sure what happened. Then playing defense the next inning, it got worse and worse. I didn't want to hurt the team by being out there so I took myself out."

In 14 games over two big league stints with the Reds this season, Valaika batted .280 (7-for-25) and made seven starts. He batted .261 with seven homers and 37 RBIs this season at Triple-A Louisville.

This is the second time that Valaika has torn the same ACL, with the previous time happening during a collision with an outfielder as a college player. However, he didn't feel as though he blew out his knee this time.

"I was pretty surprised, too," Valaika said. "It didn't hurt, but it just didn't feel right rounding the base. You know your body, and it didn't feel 100 percent."

Valaika, primarily a second baseman, made two starts at shortstop this season. He should be in camp next year competing for a middle-infield roster spot.

"He came in today on crutches, he apologized," Reds manager Dusty Baker said. "There is nothing to apologize for. He really wanted to play and be part of the team. He is a fine young man that we all like having around. He stayed ready to play. It's a pretty big blow for him, but modern medicine has a way of fixing and healing compared to before."

Jocketty not talking about his contract situation

CINCINNATI -- Reds general manager Walt Jocketty is loath to discuss contract negotiations about his players. Therefore, it was hardly a surprise Monday when Jocketty declined to discuss his own contract. His four-year deal as GM and president of baseball operations ends this year.

"I don't want to talk about my situation," Jocketty bristled. "It's like any other contract. I don't like talking about it. It's not for public consumption. It's not worth commenting on it."

Jocketty was named the 2010 Sporting News executive of the year after the Reds claimed the National League Central title. Before Monday's game vs. the Cubs, his team's elimination number from the division race was two.

There will be other contract situations to discuss this fall, including whether or not to pick up the $12 million club option on closer Francisco Cordero. Jocketty indicated there was a chance the Reds would extend his contract. Cordero, 36, is on record that he would like to retire with the team. The Reds do not have many viable options in-house to replace Cordero.

"It's possible. We've got an option," Jocketty said of doing something with Cordero. "We have to address it somehow before the end of the season -- whether we pick up the option or if we extend him or whatever."

Worth noting

Shortstop Zack Cozart, who already had season-ending Tommy John surgery on his left elbow, is scheduled to have surgery next week to clean out his right ankle. Cozart is expected to be fully recovered from both procedures in time for Spring Training next year.
