KANSAS CITY -- White Sox manager Ozzie Guillen offered a tip of the cap to North Side counterpart Lou Piniella upon hearing the news that Piniella had decided to retire as Cubs manager following Sunday's game.

"A lot of years in baseball, a Hall of Famer," Guillen said.

Though initially surprised that Piniella had decided to step down now rather than follow through on earlier plans to manage through the end of the season, Guillen said he understood that family considerations and the weight of unfulfilled expectations with this year's Cubs could be a heavy burden.

"I wish I could have a career like him," Guillen said. "When my time comes, I want my name to be like Lou's was in a managing career. A lot of people forgot how good he was as a player because of all he did while managing. When you say Lou, Tony [La Russa], Bobby [Cox], Joe Torre, and you have your name there, it's a privilege."

Long familiar with the Chicago baseball scene, Guillen understands the unique challenges of managing on the North Side.

"The expectations on that side of town are higher," Guillen said. "There's no question about it."

Jenks enters early to help fatigued 'pen

KANSAS CITY -- Bobby Jenks took one for the team on Sunday.

With the White Sox bullpen burdened by injury and fatigue, the right-hander abandoned the normal closer's role and transformed himself into an innings-eater in the 3-2 loss. Jenks worked three scoreless innings from the seventh through the ninth in a tie game.

Because the White Sox offense couldn't break through, Jenks' effort didn't translate into a Chicago victory. But manager Ozzie Guillen certainly admired how Jenks responded to the abnormal situation.

"Thanks to Bobby," Guillen said. "He knows how the bullpen was beat up. He gave us three innings. When you have a player with a desire to go more than what you think it's supposed to be, I appreciate that."

With the White Sox having an off-day on Monday to recuperate, Jenks is expected to return to his normal late-game role.

Pena to stay in 'pen despite solid start

KANSAS CITY -- Despite Tony Pena's success as an emergency starter on Saturday, White Sox manager Ozzie Guillen said he can't envision Pena moving out of his normal relief role.

Pena filled in admirably for Edwin Jackson in Game 2 of Saturday's doubleheader. Jackson had burned his start in a rainout on Friday, and Pena was summoned to start the following day as the White Sox chose to be cautious and not bring Jackson back.

Pena delivered seven innings and left with a 6-4 lead. He threw 91 pitches and the five hits that he allowed all came in the fourth inning. Pena didn't issue a walk.

"The highlight of my year was Pena [Saturday] night," Guillen said. "You play an extra-inning game [in Game 1] and then you've got Pena, who never throws more than two or three innings."

Guillen had Mark Buehrle and Gavin Floyd in the bullpen for help, but they weren't needed as Pena made it through seven. Nevertheless, Guillen doesn't want to toy with the idea of making Pena a starter.

"I don't take that chance," Guillen said. "A lot of people think it's easy when you do something for one day. But doing it every day? That could be very tough."

Thornton still dealing with forearm discomfort

KANSAS CITY -- The White Sox plan to further evaluate left-handed reliever Matt Thornton after they return home from Kansas City. Thornton has been dealing with left forearm discomfort and was unavailable again on Sunday.

"It's just sore," manager Ozzie Guillen said of Thornton.

Thornton hasn't pitched since last Tuesday in Minnesota. For as long as Thornton is out, rookie Chris Sale will take on an even more prominent role. Sale, the first player from the 2010 First-Year Player Draft to appear in the Majors, has been impressive. Left-handed hitters are just 1-for-7 against him.

Ozzie has wish list for upcoming callups

KANSAS CITY -- White Sox manager Ozzie Guillen emphasizes that September callups are "not my department." But that doesn't stop Guillen from having a wish list.

With the opportunity to expand Major League rosters just over a week away, Guillen cited a need for catcher and bullpen reinforcements.

"I need a catcher, for sure, and maybe a couple more arms in the bullpen," Guillen said.
