Teahen returns from DL, Marquez designated

CHICAGO -- The White Sox reinstated utility man Mark Teahen before Sunday's game against the Tigers, ending his stint on the disabled list dating back to May 12.

Teahen, who aggravated a right oblique muscle strain during a May 11 game against the Angels, returned after an eight-game rehab assignment with Triple-A Charlotte. He went 6-for-31 in his time with the Knights, playing mostly third base, but also seeing action at first base and one game each in right and left field.

"I kind of worked my way through it," Teahen said. "But now I've played eight days in a row or whatever it was and [the oblique] held up good and got looser as I went, so it's good. I'm ready to go."

Ten of Teahen's 11 starts before his injury came at third base, but he also saw action at first base, left field and right field, which manager Ozzie Guillen said will help when he's trying to get rest days for some of his regulars.

"Now's the time it's starting to get hot, and now we can get a break a little bit to Carlos [Quentin] and [Adam] Dunn and [Paul Konerko]," Guillen said. "And having [Teahen] here, gives me an opportunity to play [Brent] Lillibridge in center field and have [Alex] Rios out, and have more activity in the lineup."

Reliever Jeff Marquez, who didn't make any appearances after being called up on May 30, was designated for assignment to make room for Teahen. The three-week stay on the DL was considerably shorter than last year, when Teahen missed more than two months of the season after fracturing his left middle finger in a May 30 game.

"It's aggravating," said Teahen about the missed time. "Last year with the finger, that was totally random, but this year, thankfully, it was only a couple weeks and now I can get back in there and help out."

Konerko back in the White Sox lineup

CHICAGO -- Two days after a procedure to dislodge loose bone fragments in his left wrist, Paul Konerko was back in the White Sox starting lineup on Sunday.

Konerko, who missed the previous two games while waiting for the soreness to go away, went 2-for-4 with a pair of doubles, an RBI and a walk in Sunday's 7-3 loss to the Tigers.

"The best it felt all day was when I tested it early in the day," Konerko said. "The hard part is just keeping it loose all day. It was hot and cold and every time it got a little warmer, it backed off. It's going to be like that probably the next few days and, hopefully, it gets a little easier every day. Maybe 70, 80 percent. Some swings bothered it, some swings didn't. I tried to not swing if I didn't have to."

Konerko has said his wrist is something that has bothered him for years, but flared up only a few times each season and it was usually while doing off-field activities. After Wednesday's game, however, it locked up on him and he couldn't jar the fragments loose on his own as he usually does. So before Friday's game, he had them flushed to another area in his wrist that doesn't bother him.

He returned to the lineup as the second-best run producer in the American League, entering Sunday's game with 44 RBIs to go along with his .310 batting average and 12 home runs. Adam Dunn, who played first base in Konerko's absence, moved back to the DH spot on Sunday, going 1-for-4 with three strikeouts.

Rios taking mental break as struggles continue

CHICAGO -- White Sox center fielder Alex Rios will get a few days off after his struggles at the plate continued on Saturday night as he went 0-for-3, grounding into a pair of double plays.

Manager Ozzie Guillen made it clear that he wasn't taking Rios out of the lineup for a lack of production, but he simply wanted to give his outfielder a few days off because of the growing frustration Rios has shown with himself. Guillen spoke to his center fielder after Friday night's game about his body language on the field and slamming a Gatorade container in the dugout after a first-inning groundout with the bases loaded.

"I give the players the best opportunity to go out there," Guillen said. "But I think Rios, right now, mentally, is very frustrated, very disappointed. I'm going to give him a couple-day break to hopefully recover and get his stuff together."

Guillen has said Rios' struggles are especially frustrating because he has been making mostly good contact with the ball, but hasn't found the gaps. He has struck out only one time in his last 43 at-bats, but also has only eight hits in that time.

"I talked to him [on Saturday] about the plans we have," Guillen said. "So, hopefully, when he comes back in the lineup, he's ready to play."

Brent Lillibridge, who had homered three times during a seven-game hitting streak, took Rios' spot in center field on Sunday, batting sixth, but went 0-for-3.

Winning series will take care of standings

CHICAGO -- Ozzie Guillen knows it's important for his club to win every series, especially against American League Central foes. Apparently, he doesn't put as much emphasis on the team's place in the standings in early June.

"To be honest with you, I don't even know where we are right now," Guillen said. "I'm not a stats guy. We can be in first place July 1 and be in last place July 3. I think we're playing well right now; Hopefully, we continue to play well."

Coming off a 5-5 road trip that ended with a three-game sweep of Boston, the White Sox dropped two of three to the Tigers to start a 10-game homestand. The White Sox went 5-2 on their last homestand from May 15-22, and hadn't lost a home series since losing a two-game set to the Twins May 3-4.

"Obviously we need to win every series," second baseman Gordon Beckham said before Sunday's 7-3 defeat to the Tigers. "They're a little bit ahead of us and they're a team that's probably going to be there at the end, so anytime you can beat them, it's important."

Third to first

• Carlos Quentin was hit by a pitch for the second straight game on Sunday and a league-leading 13th time.

• The White Sox have lost 11 of their last 12 games against the Tigers dating back to last season.

• Gordon Beckham and Detroit's Miguel Cabrera each homered in back-to-back games. For Beckham, it was the first time he's done that since Aug. 24-25, 2010.
