CLEVELAND -- Mark Buehrle, Jake Peavy and John Danks will start in that order during an important three-game home series beginning Monday night against the Tigers.

Philip Humber, the White Sox most consistent first-half starter, moved to the bullpen for Sunday's series finale in Cleveland and will be available in relief when facing Detroit. The move was not intended to bring an end to the White Sox six-man rotation.

"Temporarily," said White Sox manager Ozzie Guillen of Humber's bullpen move. "I think Humber needs a little bit of a break, that's the only reason we're doing it.

"And I don't want those guys to miss starts. I don't want them to stay that long. That's a lot of days without throwing and then we can use this kid out of the bullpen, because he's the only one we can use out of the bullpen. Last time we used Peavy out of the bullpen, he got in trouble."

Humber has made 17 starts out of his 19 appearances this season, posting an 8-6 record with a 3.26 ERA over 113 innings. Although Humber has said he feels great, the right-hander is approaching his single-season professional high of 148 innings and has allowed 10 runs on 18 hits over his last 9 1/3 innings.

Sunday's news seemed to slightly unnerve Humber, who didn't receive an indication from White Sox pitching coach Don Cooper during a morning discussion as to how long his starting absence would cover. Humber is ready to do whatever is asked of him, following a mantra he has espoused all season.

"I'm good with it, whatever they want me to do," said Humber, who last pitched on July 17 at Comerica Park against the Tigers. "I've said all along, 'When they give me the ball, I'll do the best I can with it.'

"Now I have a chance to pitch today, tomorrow or the next day, so we'll see what happens. I think we've got a bunch of guys throwing the ball well. And hopefully, I'll have an opportunity to help them in the bullpen."

Viciedo exits Minors game with thumb soreness

CLEVELAND -- Dayan Viciedo was replaced by Gookie Dawkins during the sixth inning of Triple-A Charlotte's victory over Louisville on Saturday, after Viciedo grounded out in the top of the frame. Many believed Viciedo's early departure signaled his impending big league callup, but instead it was about right thumb soreness felt by the right fielder.

Viciedo had some swelling this past week in the area where he suffered a fracture during Spring Training when hit by a David Bush pitch. But the injury is not considered serious.

The slugging outfielder and White Sox top prospect has been the topic of conversation since early June, with many believing Viciedo could be the instant boost needed by the sluggish Chicago offense. Viciedo told MLB.com in early June that he was Major League ready and has been backing up that talk on the field with a .307 average, 16 home runs and 65 RBIs.

General manager Ken Williams also talked about Viciedo being able to contribute immediately, but was in agreement with manager Ozzie Guillen that he needed to play regularly if brought up. Guillen mentioned on Sunday that he would like to have Viciedo with the White Sox, but he still has no place for him.

"Where is he going to play?" Guillen said. "Now the people they want out are the best players I have. [Carlos] Quentin is going to be on the bench or Juan [Pierre] is going to be on the bench? Who else out there? [Alex] Rios is going to be on the bench? Who plays center field?

"They hate how Pierre plays left field. How is he going to play center field? Adam Dunn, we are going to bench Adam Dunn? It's a lot of things.

"I have to call this kid every other day to make sure he knows I don't hate him. They put me on the spot where Viciedo might think, his agent and his family, that I don't like him. I do like this kid. In the meanwhile, I wish I had the solution. I wish I could play 10 players like a softball game, play him in the middle of the field, and then we bring him [up]."

Guillen added that if players such as Dunn and Rios, among others, were hitting to their normal level, then Viciedo wouldn't even be part of the conversation until September.

Vizquel doing his job as a reserve player

CLEVELAND -- Don't judge Omar Vizquel simply by his .268 average and eight RBIs he brought into Sunday's start at Progressive Field. As Ozzie Guillen explained, the 44-year-old veteran has value well beyond his production.

"Omar has been great since we got him. He does his role very well," Guillen said. "He has been playing pretty well. He hasn't had as much playing time, but every time he contributes to the ballclub.

"He's great in the clubhouse and in the dugout, a lot of people lean to him and talk to him. Like I said two months ago, 'This kid can play another two years.' He keeps himself in great shape."

Vizquel had 344 at-bats last season, hitting .276 with 30 RBIs as the team's regular third baseman during its 28-8 midseason hot streak. But Guillen explained the White Sox are not the team they want to be if Vizquel is getting that much playing time, as opposed to his designed reserve role.

In Sunday's 4-2 victory over the Indians, Vizquel picked up career hit No. 2,833, scored the go-ahead run in the sixth and made a slick defensive play at second to end the game.

Trade rumors swirling around White Sox

CLEVELAND -- According to a report from the St. Louis Post-Dispatch, trade talks between the White Sox and Cardinals centering on left-handed-hitting outfielder Colby Rasmus have accelerated in recent days. Rasmus has been a player of interest since this past offseason, as first reported by the Chicago Sun-Times.

The report talked about Sunday starter Edwin Jackson, who will be a free agent after the 2011 season, or left-handed reliever Matt Thornton as potential St. Louis targets. Jackson could be moved without weakening the current rotation, as the White Sox are working with six quality starters.

Thornton agreed to a two-year, $12-million extension with a 2014 club option during Spring Training. The White Sox have three lefties in the bullpen, with Thornton, Chris Sale and Will Ohman, and were impressed with the work turned in by southpaw Hector Santiago during his short Major League stint. They already are loaded in the outfield, though, as shown by the lack of room to promote hot-hitting prospect Dayan Viciedo.

When asked for comment about the matter, general manager Ken Williams told MLB.com via e-mail that he will be available to chat on Monday after Ozzie Guillen's pregame press session. Jackson, who earned the win in Sunday's 4-2 victory over the Indians, already had heard the rumor but took the trade rumblings in stride.

"My name is in trade rumors every year," said Jackson, who would like to stay with the White Sox. "It's been like this for the last five years. It's definitely nothing I worry about. I can't control it. I just want to play wherever I'm wanted to play."

Third to first

• Carlos Quentin is hitting .462 with 12 RBIs and five runs scored in seven games this season vs. the Indians.

• Sergio Santos made his 21st straight scoreless appearance on the road in Sunday's 4-2 victory, covering 23 1/3 innings. Dating back to 2010, Santos has made 26 straight scoreless road appearances, covering 27 2/3 innings.

• The White Sox are 38-29 since May 7 and 28-21 this season against teams with winning records.

• Edwin Jackson is 9-1 lifetime against the Indians and 5-0 with a 1.90 ERA at Progressive Field.
