Rick Porcello (6-10-7-1-3, 101) had a bad night.
Porcello did not retire any of the first four Astros in the first inning: George Springer doubled, Marwin Gonzalez reached on a bunt single, Jose Altuve doubled in a run, and Carlos Correa walked. Houston then got two sacrifice flies from Brian McCann and Carlos Beltran and took a 3-0 lead.
The Astros doubled their lead to 6-0 in the third. Altuve led off with a home run to left center. Correa singled. One out later, Beltran homered to right. Porcello threw 64 pitches in the first three innings.
