Qualls earned his first win of the season in relief Wednesday against San Francisco. The veteran right-hander struck out a better during a perfect eighth inning of a 3-3 tie before the Astros took the lead in the bottom of the frame. Qualls, who temporarily filled the closer role for Houston while Luke Gregerson was on the Family Medical Emergency List, has a .176 BAA and 16:3 K:BB ratio with three saves and four holds in 14 appearances this season.
