Belisario is signing with the Red Sox, Jon Heyman of CBS Sports reports. Belisario was fairly awful with the Rays in 2015, throwing a 7.88 ERA in 8.0 innings and spending most of his time in Triple-A Durham, but he could still be an asset to a Boston bullpen in the bottom 10 of the majors in ERA and second-worst in FIP. He might land in Triple-A to begin, but it's likely he hits the majors before long.
