Jon Heyman of SI.com hears that there are two "mystery teams" interested in free agent Chad Qualls. It's hard to tell whether Heyman is joking, but we'd imagine Qualls is drawing interest from multiple clubs. The 33-year-old right-hander posted a 3.51 ERA, 1.25 WHIP and 43/20 K/BB ratio over 74 1/3 innings this season, though he enjoyed most of his success within the comfy confines of PETCO Park. The Padres declined his $6 million option for 2012 in October.
