HOUSTON -- As of two games ago, Jason Castro had never hit a homer off a left-hander. Now Houstons left-handed hitting catcher has done it twice. Castro homered for the second straight game and Matt Dominguez hit a three-run double to help the 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. "Jason has definitely found his groove and understands exactly what it is hes doing," manager Bo Porter said of Castro, whose first 16 homers came against right-handers. "Hes healthy, his legs are underneath him, and its allowing him to put together an All-Star type season." He has a career-high 10 home runs this season, the second-most among catchers in the American League. "Im feeling comfortable," Castro said. "Theres some things Ive been working on with some of my pitch recognition and things like that. So I think its coming along. Its definitely a work in progress." 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 (4-3) yielded four hits and two runs in 6 1-3 innings for the win. He continued a streak of solid starting pitching for the Astros, whose starters have gone 11-8 with a 3.03 ERA since May 15. "The starting pitching has been tremendous," Porter said. "You look at this stretch in which weve played really good baseball ... it starts and ends with those guys on the mound." Hector Santiago (2-5) 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 (28-38) for the first time since May 7, 2011. They have had trouble scoring in this span and have been outscored 71-41. "Offensively, we are not getting it done," Chicagos Adam Dunn said. "If I could sit here and put a finger on why (I would), but I cant. For once, I am speechless. I dont know why our offence is sputtering. "We have the talent. We have everyone in place. We just arent producing." 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 Tals Hill in centre 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 Dunn singled. But Keuchel retired the following nine hitters, with Chicagos 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. NOTES: Houstons game on Saturday night ended when Veras picked off Jordan Danks at second base.
