Slump-ridden Tyler Flowers drove in the go-ahead run with a seventh-inning double, and four Chicago pitchers retired the final 22 batters to lift the White Sox to a 3-2 victory over the Houston Astros on Friday night.

Alejandro De Aza singled off Scott Feldman and stole second before Flowers delivered the game-winning hit. He entered the game with only 12 hits in his last 116 at-bats, and a .218 batting average overall.

Daniel Webb (5-2) retired the six batters he faced in relief of Jose Quintana to earn the victory. Zach Putnam pitched a scoreless inning for his second save of the season.

After Quintana allowed a pair of unearned runs, he set down the final 10 batters he faced. The left-hander allowed three hits and two walks in five innings.

Feldman (4-7) took a four-hit shutout into the sixth inning, when Dayan Viciedo hit a two-run homer into the left-center field bleachers to tie it. Just three batters earlier, Feldman was struck on the backside by a smash off the bat of Alexei Ramirez.

In seven innings, Feldman allowed three runs, seven hits and three walks.

Aided by a two-base error, Houston took a 2-0 lead in the second inning. After Jon Singleton's single eluded Viciedo in right field, Matt Dominguez scored from first base while Singleton continued to third. Robbie Grossman followed with an RBI groundout.

Adam Eaton tripled, and Jose Abreu doubled in the first inning, but Chicago failed to take an early lead. Grossman threw out Eaton at the plate on a shallow fly ball to right field, a call upheld by video replay after a White Sox challenge.
