The White Sox look to complete a series sweep and maintain their dominance over the Royals when the teams wrap up their weekend series on Sunday.With a 5-4 win in 10 innings on Saturday night, Chicago improved to 5-0 this season over their AL Central rivals and is 25-6 at home against the Royals since 2004.Chicago trailed 4-3 in the ninth, before Darin Erstad reached on a two-out single and scored on Juan Uribe's double. After Paul Konerko walked to lead off the 10th, pinch runner Luis Terrero took second on a wild pitch and scored on Jermaine Dye's single.Dye, who played with the Royals from 1997-2001, entered the game in an 0-for-13 slump and was hitting just .193 for the season before his first two-hit game since April 27. The right fielder set career highs last season with a .315 average, 44 homers and 120 RBIs."Hits haven't been coming too good for me," Dye said. "My mind-set today was try to get one hit and go from there, stay positive, keep swinging and sooner or later, I'll come out of it. Hopefully tonight is a start."Chicago's fourth win in a row tied a season high. To help the White Sox (18-16) achieve their longest win streak since a five-game run last Aug. 10-14, Javier Vazquez (2-1, 3.52 ERA) hopes his second start of the season against Kansas City goes better than his first.The right-hander did not earn a decision in the White Sox's 9-7 win at Kansas City on April 24, when he allowed a season-high five runs in six innings.However, he went 2-1 with a 2.14 ERA in three starts versus the Royals last season at U.S. Cellular Field.In four starts since beating Cleveland on April 13, Vazquez is 0-1 with a 4.44 ERA. He pitched well against Minnesota on Tuesday, allowing a run and four hits in seven innings, but didn't get the decision in a 10-inning, 7-4 loss.A two-run homer by Kansas City's John Buck capped a four-run fourth inning on Saturday, but the Royals (11-26) lost their third game in a row and seventh in the last eight.Making his first career start against the White Sox, Jorge De La Rosa (3-3, 4.06) will try to break a tie with marquee free-agent signee Gil Meche for the team lead in wins.The left-hander, who has alternated wins and losses in his last four starts, is coming off his shortest outing of the season. He suffered his first home loss in Tuesday's 6-1 defeat against Oakland, allowing season highs of six runs and 10 hits in 4 1-3 innings.De La Rosa entered the game with an AL-leading 0.82 ERA at home, but saw it balloon to 2.39."His curveball wasn't as good as it has been," Royals catcher Jason LaRue said. "He was more erratic tonight."De La Rosa has yet to win on the road in 2007, going 0-2 with a 6.50 ERA in three starts.
