According to Juan C. Rodriguez of the South Florida Sun-Sentinel, the Marlins are interested in right-hander Juan Morillo, who was recently designated for assignment by the Rockies.
Morillo, 25, made Colorado's Opening Day roster, but didn't appear in a game and was dumped Friday when the club decided to call up Matt Belisle. Morillo may never turn into anything more than a decent middle reliever, but he boasts a fastball that can reach into the high 90s and he's had a decent amount of success in the minors.
