Jason Castro homered for the second straight game and Matt Dominguez hit a three-run double to help the Houston Astros to their fourth straight win, 5-4, over the Chicago White Sox on Sunday.
Dominguez put Houston on top 3-0 with a double in the second inning, and Castro hit a two-run shot to make it 5-2 in the seventh.
The left-handed Castro hit his first career home run off a left-hander on Saturday night when he connected off John Danks, and made it two when he hit a slider from Matt Thornton on Sunday.
Alejandro De Aza tripled and scored in the sixth and Dayan Viciedo tripled and scored in the seventh to cut the lead to 3-2. De Aza added a two-out, two-run homer off Jose Veras to make it 5-4 in the ninth before Alexei Ramirez grounded out to give Veras his 14th save.
Houston starter Dallas Keuchel yielded four hits and two runs in 6 1-3 innings for the win.
Hector Santiago allowed five hits and three runs with eight strikeouts in 5 1-3 innings.
The AL-Central-worst White Sox have dropped four straight overall and 12 of their last 13 road games to fall 10 games under .500 for the first time since May 7, 2011. They have had trouble scoring in this span and have been outscored 71-41.
Chris Carter singled with one out in the second before Santiago issued consecutive walks to load the bases. Dominguez cleared the bases with a double which skidded down the left field line, just out of reach of a diving Jeff Keppinger to make it 3-0. He advanced to third on the throw home.
Brandon Barnes robbed Viciedo of a hit when he raced up Tal's Hill in center field and made an over-the-shoulder grab before falling and rolling into the wall to start the second inning.
The White Sox got their first hit the next batter when Adam Dunn singled. But Keuchel retired the following nine hitters, with Chicago's next runner coming when Keppinger walked with one out in the fifth.
De Aza tripled to start the sixth inning, and Chicago cut the lead to 3-1 when he scored on a sacrifice fly by Ramirez.
Viciedo led off the seventh with a triple and scored on a one-out single by Keppinger that got Chicago within 3-2 and chased Keuchel.
He was replaced by Jose Cisnero who was greeted with a single by Gordon Beckham before pinch-hitter Conor Gillaspie walked to load the bases. Cisnero escaped the jam by striking out De Aza before Ramirez grounded out to end the inning.
