SAN FRANCISCO — Ronel Blanco had eight strikeouts in six innings, Mauricio Dubon scored twice and the Houston Astros beat the San Francisco Giants 3-1 on Tuesday night.
Blanco (6-2) allowed one run on three hits and became the first pitcher in Astros history to go undefeated in his first nine career road starts, improving to 6-0 away from home. His eight strikeouts tied a season high.
The right-hander said his fastball, slider and changeup were all working — but he went to his fastball more often than his off-speed pitches and caught some of the Giants batters off guard.
''We needed a good outing from Blanco, and he gave us that,'' Astros manager Joe Espada said.
Houston took a 3-1 lead in the fifth when two runs scored on an RBI infield single by Alex Bregman. With two outs and runners on second and third, Gold Glove third baseman Matt Chapman grabbed Bregman's softly hit ball with a bare hand but threw wide of first for an error, allowing both runners to score.
Espada credited his team for putting the ball in play in RBI situations, with all its runs scoring on balls that didn't leave the infield.
''Anything can happen when you put the ball in play, and we did that there with two outs,'' Espada said. ''You don't see Chapman throwing many balls away, but we were fortunate enough that he threw one away.''
Ryan Pressly earned his second save of the season, striking out two in the ninth. Houston held the Giants to three hits, their season low.
