Houston Astros Edge Chicago Cubs 2-1

The Houston Astros extended the Chicago Cubs losing streak to a season-high eight games Tuesday night with a 2-1 win.

Left-fielder J.D. Martinez has had a bad month at the plate, but he belted the go-ahead RBI single in the sixth while second baseman Jose Altuve accounted for the teams other score with a solo homer run.

Martinez hit .282 in April, but is 6 for 50 in May to drop his average to .219.

Houston starter J.A. Happ (4-3) won his second consecutive start by allowing one run and five hits in six innings, while striking out six batters, and the bullpen retired nine of the 10 batters it faced, including seven by strikeout. The 13 strikeouts by the Astros tied a season high.

Happ is 2-0 with a 0.75 ERA in his last two starts.

"Happ threw the ball great," closer Brett Myers said. "That's back-to-back [good] starts for him, and I think he's back. He and [catcher Chris] Snyder worked fast, and that keeps Happ's rhythm going and being able to locate pitches. He's throwing the ball really well for us."

Myers pitched a perfect ninth for his 11^th save.

Alfonso Soriano hit a homer to left-center to lead off the fourth, tying the ball-game. Soriano has four homers in his last eight games after going 30 games without a homer to start the season.
