Astros 2, Cubs 1: J.A. Happ allowed one run over six innings as host Houston won for the fifth time in seven games and sent Chicago to its eighth straight loss.

J.D. Martinez’s sixth-inning RBI single snapped a 1-1 tie and the Astros held on from there as Chicago matched its longest losing streak since May 30-June 7 last season.

Happ (4-3) allowed five hits, striking out six and walking two. Wesley Wright and Wilton Lopez bridged the gap to Brett Myers, who notched his 11th save with a perfect ninth.

Travis Wood (0-1), recalled from Triple-A to take Chris Volstad’s spot in the rotation, was the hard-luck loser. Wood yielded two runs and two hits over 5 2/3 frames.

Jose Altuve led off the game with a homer for Houston, but Alfonso Soriano tied it in the fourth with a solo blast. That marked the first time the Cubs had scored against a starting pitcher in four games.
