Qualls struck out a batter during a scoreless inning of relief Tuesday against Oakland to pick up his fifth hold of the season. While Luke Gregerson opened 2015 as the Astros' closer and has kept the role through the first month-and-a-half of the season, Qualls has maintained his fantasy value with a win, four saves, five holds, a 2.93 ERA, 0.78 WHIP and 18:3 K:BB ratio over 15.1 innings.
