Rangers starter Andrew Cashner had just one bad stretch, and it came in the third inning, when six straight batters reached base with one out to send home four runs. Carlos Beltran hit a two-run single that inning to go with his home run in the second.
The Astros are now 40-16 with the best record in the Major Leagues and their best start after 56 games in club history. The previous best was 34-22. The Astros have also won their last nine straight road games, the second-longest streak in club history.
The Rangers have lost 10 of their last 13 after their own 10-game winning streak ended.
