Astros signed RHP Chad Qualls to a two-year, $9.5 million contract. The deal includes a club option for 2016. The right-hander fell on hard times in 2012 but rebounded to post a 2.61 ERA and 1.23 WHIP as a middle reliever with the Marlins this past season. Qualls, who saved 24 games as recently as 2009, could also see some late-game action with Houston.
