Qualls has been claimed off of revocable waivers by the Tigers, MLive's James Schmehl reports. With this development, Qualls could soon join the Tigers' bullpen. However, there is no guarantee that a deal will materialize, as the Astros do have the option of hanging on to their veteran closer. The two teams have until Wednesday to come to an agreement. Qualls has turned in a solid campaign in Houston to this point, converting 14-of-17 save chances while posting a 3.07 ERA and 38:5 K:BB ratio across 44 innings.
