As expected, Gordon Beckham wasn't able to play Sunday due to a strained muscle in his right side.
Beckham hurt himself on his final batting practice swing Saturday. He was in the starting lineup but came out of the game in the bottom of the first inning.
White Sox manager Ozzie Guillen said Beckham isn't likely to play today, either.
"Those types of injuries or soreness, it can come out pretty bad and he'd miss 15 to 21 days," Guillen said. "That's why we want to make sure he's 100 percent ready to go because that costs a lot of days, and this kid's had a good season, and hopefully he has a good shot to be Rookie of the Year.
"Plus, we've got (24) games left and I need him the most I can. We have to be very careful how we're going to treat him."
Blame it on Rios: Alex Rios was 0-for-3 with 3 strikeouts Sunday, and the outfielder was booed loudly following the final whiff.
It has been a tough transition for Rios, who was claimed off waivers from Toronto on Aug. 10 and is 4-for-46 over his last 12 games.
"He's kind of confused right now," manager Ozzie Guillen said. "You come from one ballclub to another, there are a lot of expectations. You've got a tendency to try to carry this ballclub. I told him, 'Hey, I don't need 30 home runs. Give me 20 bloopers and steal five bases. That's what we need from you.'
"Hopefully he starts to come around pretty soon. But he'll be fine. He's a good ballplayer and I expect him to have a good year for us."
Playing the field: Jim Thome is no longer with the White Sox, giving manager Ozzie Guillen several options at designated hitter. Scott Podsednik filled the spot Sunday while batting in his customary leadoff spot.
Paul Konerko and Jermaine Dye are also DH candidates, but Guillen said he prefers leaving Carlos Quentin in left field.
"I don't like Carlos to DH because he'll drive everybody crazy," Guillen said. "I think Carlos is the type of guy when he doesn't get a hit, he thinks a lot when he's sitting here. I'd rather when he doesn't get a hit, he goes out there and performs.
"I'll pick my spots to get him a DH here and there, but he's not a good kid to have at DH."
Contreras comes through: In his first start since being traded to the Colorado Rockies, Jose Contreras pitched 62/3 innings and beat the Diamondbacks on Saturday. Contreras, who was 5-13 with a 5.42 ERA for the White Sox, allowed 1 run on 8 hits in his Rockies debut.
"I know for a fact that Jose is going to be very, very good, and I know he's going to help those guys," manager Ozzie Guillen said. "He's healthy and he just needs to go out and perform."
Guillen doesn't have any second thoughts on the trade just because Contreras had a good start.
"We gave him all kind of chances," Guillen said. "When you lose 13 games, that means you had a lot of chances to be out on the mound."
