PITTSBURGH (AP) -- Bud Norris allowed three hits in six sharp innings and the Houston Astros edged the Pittsburgh Pirates 1-0 on Friday night.
Brian Bogusevic singled and scored in the second on a double-play grounder to provide all the offense the Astros needed in support of Norris (3-1), who struck out eight without walking a batter.
Brett Myers pitched the ninth for his ninth save.
Pittsburgh's James McDonald (2-2) extended his impressive start, giving up just four hits in eight innings while striking out eight and walking two.
Norris worked out of a bases-loaded, none-out jam in the sixth and Houston's improved bullpen made it stand up.
