Chad Qualls earned the save Sunday with a scoreless ninth inning against the Orioles. Qualls hit Ryan Flaherty but didn't allow any other baserunners en route to his second save of the season. Qualls' only other save came on April 6, so it's hard to say who's closing games for the Astros on a day to day basis. Qualls owns a 3.75 ERA and 1.75 WHIP on the year.
