Red Sox sign Ronald Belisario

Boston has been seeking bullpen help and has added a former Ray in an attempt to add depth. Ronald Belisario struggled with Tampa Bay but will sign with the Red Sox, according to CBS Sports' Jon Heyman.

Belisario, 32, posted 7.88 ERA and 3.07 FIP over eight innings with the Rays before they decided to designate him for assignment. He ultimately cleared waivers and allowed seven runs in six appearances pitching out of Tampa Bay's bullpen. Belisario posted a 3.26 ERA and 3.73 FIP over 30.1 innings with the Rays' Triple-A affiliate and could appear late in games for the Red Sox.

Heading into 2015, Belisario posted a career 3.75 ERA while averaging 7.3 strikeouts per nine innings. He posted a 5.56 ERA and 3.54 FIP with the White Sox in 2014 and has yet to establish himself as a consistent bullpen option. Belisario is a ground ball pitcher and as a result could have success at Fenway Park.

Although Belisario has struggled over the last few seasons, he could help Boston's bullpen, which ranks 23rd in all of baseball with a 3.88 ERA.
