The Rays have until tomorrow to decide.
This past January, Ronald Belisario reached a deal with the Toronto Blue Jays, before things fell apart and the Rays swooped in and signed him to a minor league deal. Heading into spring training, Belisario was in line to compete for a spot in the Rays pen, but unfortunately he fractured his left shoulder prior to spring training and wasn't be able to take part in the runup to the season.
Last year, Belisario was part of the White Sox closer by committee and seemed to suffer from some bad luck.
