Qualls earned his 15th save of the season Tuesday with a scoreless frame against the A's. Qualls was claimed off revocable waivers by the Tigers on Tuesday, but the veteran reliever did not let the news affect him in preserving a 4-2 win over Oakland. The Astros and Tigers have until Wednesday to work out a trade, but there's a strong likelihood Houston will pull Qualls off waivers rather than trade him.
