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.

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.

Ryan Pressly earned his second save of the season, striking out two in the ninth to finish a three-hitter. The Astros can pick up their third consecutive series win with a victory on Wednesday.

Both teams scored a run in the third. Dubon came home on Jose Altuve's groundout after hitting a leadoff double, and Brett Wisely homered for the Giants. Dubon, who played for San Francisco from 2019-22, went 2 for 3 with two doubles.

Giants starter Jordan Hicks (4-3) allowed three runs in 4 2/3 innings.
