CINCINNATI -- Reds rookie left fielder Yonder Alonso wasn't in Monday's starting lineup and likely won't be the rest of the 2011 season. Alonso has been dealing with a bone bruise in his right ankle.

"We're probably going to shelve him just to pinch-hit," Reds manager Dusty Baker said.

Alonso, 24, was originally injured during a game at Wrigley Field in early August. The injury was aggravated when he fouled a ball off of his ankle on Saturday.

"I kind of kept it a secret a little bit and tried to play through it," Alonso said. "For some reason the past week, it's just been killing me. It's just a bone bruise. There is no tendon issues, no surgery. I'll deal with it and move forward. It's going to hurt. It's been hurting me for a month and a half."

Since his July 22 recall from Triple-A Louisville, Alonso has been impressive at the plate. In 40 games entering Monday, he is batting .346 with five home runs, 15 RBIs and a .418 on-base percentage.

After an initially rocky first few games at his new position of left field, Alonso became more competent in recent weeks and will dedicate his entire offseason to shedding some weight and focusing on becoming a full-time left fielder.

As far as the 2011 season is concerned, there is no more time in left field planned.

"At the end of the day, I don't want to embarrass the team and I don't want to embarrass myself," Alonso said. "I don't want to hurt the team on a ball I couldn't catch. That was my concern and that's what I told Dusty."

Willis scratched from second straight start

CINCINNATI -- At around 3:30 p.m. ET on Monday, the Reds posted a starting lineup that featured Dontrelle Willis as their starting pitcher. About 15 minutes later, Willis was scratched and Travis Wood was named the starter.

Willis was originally scheduled to pitch Sunday vs. the Brewers, but was pushed back because of back spasms. Wood was already listed as a possible replacement before the decision was finally made.

"It was kind of made for us," Reds manager Dusty Baker said. "Dontrelle's back is still the same. He went to a chiropractor. It was better when he left but the more he walked around, the tighter it got again."

There is no word on when Willis might be able to pitch again. Wood last pitched in relief on Saturday, working 1 1/3 scoreless innings with three strikeouts.

Worth noting

• Jay Bruce (92 RBIs) and Joey Votto (98 RBIs) could become the 14th set of Reds teammates to produce 100 RBIs in the same season and the first to do it since 1977, when George Foster had 149 RBIs and Johnny Bench had 109.
