Chicago, IL (Sports Network) - Carlos Quentin and A.J. Pierzynski both clubbed two-run homers, as the Chicago White Sox downed the Kansas City Royals, 9-5, in the opener of a three-game series from U.S. Cellular Field.

Gavin Floyd (6-3) gave up four runs -- two earned -- on six hits over seven innings to pick up the win for Chicago.

Pierzynski finished 3-for-4 at the plate, while Quentin also drew a pair of walks for the White Sox, who dropped the final three tests of a four-game weekend set at Tampa Bay. Chicago mustered just four runs over the three losses which drew the ire of manager Ozzie Guillen. After Sunday's setback, the fiery skipper went on a tirade, publicly calling for general manager Ken Williams to make changes and fix his team's struggling offense. Well, the team responded by pounding out 11 hits.

Alexei Ramirez belted a solo home run, doubled and singled in another run. Orlando Cabrera knocked in two runs and Nick Swisher added a solo shot.

"When our guys do well it's a great reward," Guillen said. "We have good talent here. We just have to put everything together and hope that our powerful lineup can get going. We must start living up to expectations."

Zack Greinke (5-3) was roughed up for eight runs on nine hits in six innings for Kansas City, which had won two straight following a season-long 12-game losing streak.

"He was up in the zone, over the plate," Kansas City manager Trey Hillman said of Greinke. "He just had trouble with his location all night."

Mark Teahen hit a two-run homer, while David DeJesus went 3-for-4 with an RBI and a run scored.

The White Sox grabbed a 2-0 lead in the first, as Quentin followed a one-out single by Pierzynski with a smash down the right field line.

Chicago then scored four runs in the bottom of the second to build a six-run cushion. With one out, Joe Crede singled to right and Ramirez laced a double off the leg of a sliding Tony Pena Jr. to put runners on second and third. Cabrera then poked a two-run single to center, and scored on Pierzynski's fourth home run of the season.

Kansas City got on the board with two runs in the next frame. Joey Gathright reached on Ramirez's fielding error and back-to-back singles by Pena and DeJesus plated a run. Pena later scored when Mark Grudzielanek got hung up in a rundown.

Home runs by Swisher and Ramirez in the bottom of the sixth made it an 8-2 game, but the Royals countered in the next inning on Teahen's two-run blast that cleared the wall in center.

The Royals manufactured another run in the top of the eighth, as DeJesus led off with a single, stole second and scampered home on Alex Gordon's RBI knock.

Chicago got the run back in the bottom of the eighth on Ramirez's run-scoring single.
