Kevin Youkilis singled in Alejandro De Aza with the winning run in the 10th inning on Wednesday night, giving the White Sox a 5-4 victory against the Texas Rangers in a matchup of first-place teams at U.S. Cellular Field.

De Aza walked against Mike Adams and stole second base, setting up Youkilis' heroics. Youkilis also had a strong game in the field at third base.

The Sox scored four in the second, highlighted by Alexei Ramirez's two-run singled that pushed across Alex Rios (double) and A.J. Pierzynski (hit by pitch), who was safe on right fielder David Murphy's throw when he crashed into and through catcher Mike Napoli to reach home plate.

Gordon Beckham followed by driving in Ramirez with a double to give the Sox a 4-3 lead.

Kevin Youkilis had his second good night in a Sox home uniform, making two exceptional plays at third base behind Axelrod in the fifth. Youkilis singled in the fifth and was intentionally walked by lefty Robbie Ross with Ramirez on second and Dunn up, a strategy that worked as Dunn was called out on strikes.

Sox starter Dylan Axelrod gave up three runs in the first after retiring the first two batters. Four consecutive hits, including a two-run double by Michael Young, put the Sox in a 3-0. After the Sox scored four in an entertaining half of the third to give him the lead, Axelrod allowed a homer to Josh Hamilton on an 0-2 pitch.

Axelrod finished well, exiting after 5 2/3 innings and the score tied at 4.

It was the Sox' second win against the Rangers in two nights.

Leyson Septimo, Nate Jones, Matt Thornton and Addison Reed were not scored on in relief.
