Gavin Floyd pitched 7 2-3 innings of four-hit ball and Kevin Youkilis hit a two-run homer to lead the Chicago White Sox to a 2-0 victory over the Toronto Blue Jays on Saturday.

Floyd (7-8) struck out three and walked two while improving to 3-1 with a 1.37 ERA in his last four starts. The 6-foot-6 right-hander received a standing ovation when he left in the eighth.

The White Sox have won five straight to move a season-high 10 games over .500. The AL Central leaders also have won a season-high seven straight at home.

Ricky Romero (8-4) allowed two runs and four hits in six innings for the Blue Jays, who have lost three straight.

Romero made one big mistake, and it was a costly one.

With two out in the fifth inning and Alexei Ramirez on first, Youkilis drove Romero's 1-1 pitch over the wall in center for his seventh homer of the season and No. 3 since he was acquired in a trade with the Red Sox.

With his clutch hitting and strong play at third base, Youkilis has quickly become a fan favorite in his first homestand with his new club. He has a go-ahead RBI in five games for the White Sox while hearing the familiar "Yooouk" salute from the crowd that was once a fixture at Fenway Park.

With closer Addison Reed getting the day off, Matt Thornton got four outs for his second save of the season. Jose Bautista hit a one-out drive in the ninth that left fielder Dayan Viciedo lost in the sun, but the White Sox recovered in time to cut down the All-Star slugger trying for a triple.

Bautista argued the call with third base umpire Derryl Cousins, but quickly left the field.

Brett Lawrie led off the game with a single, but Floyd did not allow another hit until J.P. Arencibia led off the sixth with a single. Arencibia was quickly retired on Lawrie's double-play ball.

Floyd entered with an 0-5 record and 7.26 career ERA against the Blue Jays.
