The division-leading White Sox (59-43) increased their lead over the third-place Tigers (52-51) to 7 1/2 games following a 7-6 win on Saturday. Carlos Quentin and Jermaine Dye hit back-to-back homers, leading Chicago to its fourth straight win and helping it maintain a 3 1/2-game lead over the second-place Twins, who the White Sox open a four-game road series against on Monday.

"We just want to find a way to keep the intensity up (on Sunday) and keep doing what we've been doing the last two games," White Sox catcher A.J. Pierzynski said.

Quentin's home run was his AL-leading 27th of the season and his fifth since the All-Star break, while Dye's was his second in as many games and 23rd of the season.

For the Tigers, who received home runs from Gary Sheffield and Magglio Ordonez, the back-to-back losses came after a four-game winning streak seemed to put them back into the AL Central race. Justin Verlander didn't help Detroit on Saturday, allowing seven runs and nine hits in four innings.

The Tigers have averaged 7.9 runs in their last eight games, but are only 4-4 during that stretch. A loss Sunday would drop them 8 1/2 games behind the White Sox, their largest deficit since they were nine games back on June 11.

Chicago, meanwhile, look to improve to 30-14 against its own division when it sends Javier Vazquez (7-8, 4.57 ERA) to the mound.

Vazquez is looking to win his first start since beating the Pirates on June 16. He pitched seven innings Monday against Texas, allowing three runs and four hits in a 6-1 loss. The right-hander matched a season high with 10 strikeouts.

Despite the loss, Vazquez feels he's heading in the right direction and manager Ozzie Guillen agreed.

"Javy threw the ball unbelievably good," he said. "If Vazquez continues to throw the ball good, it will be a great second half for us."

Vazquez is 5-5 with a 4.48 ERA in 10 career starts against the Tigers, splitting two starts versus them this year.

Zach Miner (4-3, 3.73) makes his second start of the season for Detroit. The right-hander, who has made 32 relief appearances this year, pitched six scoreless innings Monday against Kansas City, allowing three hits in a 19-4 win. It was his first start since May 17, 2007 and 18th of his career.

Miner is 0-5 with a 7.08 ERA in two starts and nine relief appearances against the White Sox. In the two starts in 2006, he allowed 10 runs and nine hits in 6 2-3 innings and he hasn't fared much better as a reliever against them this season, allowing five runs in four innings over three appearances.

Dye is 3-for-9 with a double and a home run off Miner.
