OAKLAND -- Two days after Bobby Jenks' 11th-inning meltdown in Seattle, White Sox manager Ozzie Guillen said he is sticking with his plan to consider other options at closer in order to give Jenks a chance to "regroup."

"I've been the closer for this team, this is my sixth year closing," Jenks said before Friday night's game against the Oakland A's. "I shouldn't have to go out there and prove myself over and over again. I think I've done that, and it looks like I'm going to have to do it again."

Apparently so. His struggle Wednesday against the Mariners came on the heels of Sunday's ninth-inning implosion against the Twins.

Guillen tried the same tack earlier in the season, although a save situation never arose during Jenks' brief break from closing.

"That doesn't mean he loses his job," Guillen said. "We want him to get back on track and get back to where he belongs."

Jenks said he's taking Guillen's decision as a challenge, albeit irritating.

"It's both," Jenks said. "I don't want to really overstep my boundaries as far as manager-player goes. Even Mariano [Rivera] had a couple bad games in a row. In my case, I just go out there and when I get the ball, I go out there and do my job. That's all I can do."

When asked what Jenks' problem was at Seattle, Guillen said a lack of velocity wasn't the culprit.

"His velocity was OK, 93, 94 [mph]. That wasn't that bad," Guillen said. "Location was bad. The breaking ball [wasn't] doing anything. We want him to be back, to be sharp. That's the reason we're going to do it."

Guillen said he has "a lot of options" to close games. Matt Thornton and J.J. Putz have to be at the top of the list. Putz has 105 career saves. Thornton has saved five games this season.

Quentin returns, will DH more

OAKLAND -- White Sox right fielder Carlos Quentin returned to the starting lineup Friday night against the Oakland A's after missing three games with a bruised right hand.

"We need Carlos," manager Ozzie Guillen said before the 5-1 White Sox victory. "Carlos has got to stay healthy. Carlos plays hard, one way and one way only.

"[If] those guys in the middle of the lineup stay hot, swing the bat the way they swing the bat, I don't see why we're searching for trades."

In his previous 24 games, the right-handed-hitting Quentin hit .351 with 11 home runs and 31 RBIs. He entered Friday's game hitting .244 overall with 19 home runs and 64 RBIs and went 0-for-1 with two walks and two RBIs.

The White Sox are searching for a left-handed bat for their lineup.

"I always say, 'Why [are] you looking for left-handed hitters?' ... You're looking for a good hitter. Carlos makes our lineup a lot stronger," Guillen said. "He makes a lot of people a lot better around him. The last month, he's been swinging the bat very well."

Guillen said in an effort to keep the ultra-intense Quentin healthy, he'll occasionally have him DH.

"He will DH this weekend, maybe Saturday, tomorrow, or Sunday. Ideally both," Guillen said. "But in the meanwhile, we're going to see how we do. DH is not easy. This guy when he's DHing, he looks like a bull before he goes to the ring. He's so anxious.

"This guy never stops swinging. Every time he DHs, I wear him down."

Kotsay enjoyed time with A's

OAKLAND -- When White Sox designated hitter Mark Kotsay came to the plate in the top of the second inning, he received a warm reception from the small crowd at the Oakland-Alameda County Coliseum.

A's fans still appreciate the work he did for their team from 2004-07 before he was traded to Atlanta.

"I always enjoy coming here," Kotsay said before Friday night's game. "This was a great place for me."

Kotsay hit .314 for the A's in 2004, .280 in 2005, .275 in 2006 and just .214 in 2007 when he returned to action after undergoing back surgery during the offseason.

Kotsay played for an A's team in 2006 that made the playoffs and beat Minnesota in an American League Division Series before losing to Detroit in the ALCS.

Kotsay said he enjoyed playing for manager Bob Geren "and especially having Billy [Beane] as the general manager for four years and playing on winning teams. He gave me the opportunity to get to the playoffs for the first time in my career. I definitely enjoyed my time here."

Kotasy's favorite memory from his years in Oakland came in that 2006 postseason against Minnesota when he had an inside-the-park home run at the Metrodome.

Playing against former teams is nothing unusual for Kotsay. The White Sox are his sixth team.

"My career has been a tour," Kotsay said. "I had 3 1/2 years in Florida, three years in San Diego, four years here. And then Atlanta, Boston and Chicago in the course of 2 1/2 years.

"Each place has its own set of memories, and I'm thankful for the opportunity to be wearing the uniform for 14 seasons. ... Sometimes you don't really like to think about what lies in the future as far as when the uniform comes off. I'm still enjoying it. This team that I'm on, we've got a group of guys that's pretty special. We've got a great manager that keeps it always entertaining."
