Bronson Arroyo pitched a six-hitter as the Cincinnati Reds wrapped up their home portion of the schedule Wednesday with a 2-0 win over the Major League Worst Houston Astros.

Arroyo retired the first 10 batters he faced, and did not allow a hit until Houston’s Carlos Lee led off the fifth inning with a soft single just over third baseman Miguel Cairo’s head. Arroyo walked none and struck out two. He needed just 91 pitches in his fourth career shutout and first since beating Washington on Aug. 13, 2009.

Cairo homered off Houston starting pitcher Wandy Rodriguez for Cincinnati as the Red’s finished 42-39 at Great American Ball Park.

Houston did not get a runner to third base until the eighth inning, and Arroyo responded by striking out pinch hitter Brian Bogusevic and Jordan Shafer. Arroyo improved to 8-0 with three complete games over his last nine starts against Houston with the win Wednesday.
