The Red Sox will sign right-hander Ronald Belisario, CBS Sports’ Jon Heyman reports (via Twitter).  Belisario is represented by the McNamara Baseball Group.

Belisario signed a split contract with the Rays last winter and only appeared in six big league games with the team, posting a 7.88 ERA over eight relief innings.  Belisario then elected free agency after being outrighted off Tampa’s roster.  Given how Boston’s bullpen has struggled this year, there’s certainly opportunity for the 32-year-old to find regular work in the Sox relief corps.

Prior to the 2015 season, Belisario held a career 3.75 ERA, 7.3 K/9 and 2.17 K/BB rate over 331 1/3 innings with the Dodgers and White Sox.  He’s coming off a tough 5.56 ERA over 66 1/3 IP with Chicago in 2014, though advanced metrics indicate that Belisario was rather unlucky to post such an unsightly ERA.  Belisario is a ground-ball specialist (60.9% career grounder rate), which should help him at hitter-friendly Fenway Park.
