CINCINNATI — Matt Downs doubled home the tiebreaking run with two outs in the ninth inning on Thursday and the Houston Astros held on for their first win of the season, 3-2 over the previously unbeaten Cincinnati Reds.

The Astros were the last NL team to win a game, and they did it with a little drama.

Downs, who had struck out in all three of his at-bats this season, doubled off Nick Masset (0-1) for the lead. Closer Brandon Lyon, who blew his only other save chance on opening day, gave up a pair of two-out singles before getting pinch-hitter Ramon Hernandez to ground into a forceout.

The Reds won their first five games for the first time since their 1990 championship season. They were the lone NL team left without a loss — Texas is still perfect in the AL.
