Jose Quintana pitched eight innings of two-hit ball, and Kevin Youkilis broke a tie with a home run to give the White Sox a 2-1 victory over the Texas Rangers on Thursday afternoon.
The Sox (45-37) completed a three-game sweep in a series matching division leaders.
With a thunderstorm refreshing a crowd that had baked in 100-degree heat, Addison Reed pitched a perfect ninth for the save.
The Sox have won nine of their last 12. Quintana struck out a season and career-high eight while walking one.
