Kansas City, MO -- (Sports Network) - John Danks was dominant in 7 1/3 shutout innings, as the red-hot Chicago White Sox extended their season-best winning streak to seven games with a 5-0 blanking of the Kansas City Royals.

Danks (7-6) has been one of the spark plugs for Chicago, going at least seven innings while allowing three or less runs in five consecutive starts. The southpaw allowed just five hits with five strikeouts and no walks to move above .500 for the first time since the beginning of May, when he was 2-1.

A.J. Pierzynski hit a solo homer in a 3-for-4 effort, while Scott Podsednik went 3-for-4 with two runs scored for the White Sox, who have won 13 of their last 16 road contests.

David DeJesus and Luis Hernandez each had two of the Royals' six hits, as KC dropped its fourth straight game. Zack Greinke (10-4) failed to move out of the first-place tie for most wins in the AL after yielding four runs -- two earned -- on nine hits with a walk and six strikeouts in six innings.

Greinke's earned run average now stands at a season-worst 2.00.

"It happens to me every year. I pitch the best in the beginning (of the season), struggle in the middle and usually finish strong, too," Greinke said. "I don't know why, but that happens, it seems, every year."

Pierzynski put the White Sox on the board in the second, blasting a one-out solo shot to right.

"I have nothing but the utmost respect for Zack and what he's been able to do, especially this year," Pierzynski said of his homer. "He's the best pitcher I've seen this year. The bottom line is you've got to get a good pitch off of him."

Chicago took a 3-0 lead in the third thanks to some shoddy fielding. Podsednik hit a one-out double, and Jermaine Dye drew a two-out walk. Jim Thome followed with a harmless grounder to second that went right under Alberto Callaspo's glove, allowing Podsednik to score.

Paul Konerko then drilled a double down the right field line to score Dye for a three-run cushion.

Gordon Beckham hit a one-out double in the fourth and scored on Dewayne Wise's single through the infield's right side for a 4-0 White Sox lead.

Chicago padded its lead in the seventh on Thome's RBI single, all while Danks cruised through the Royals' lineup.

After the White Sox's southpaw set down KC in order five times in the first seven innings, he appeared to tire in the eighth and ran into some trouble, exiting after the Royals loaded the bases with only one out.

Scott Linebrink came in and preserved the shutout, getting Callaspo to ground into an inning-ending double play. He pitched the ninth for his second save of the season.
