The Red Sox have released reliever Ronald Belisario, the club’s Triple-A affiliate announced on Twitter. It has not been reported whether or not Belisario exercised an opt-out clause of some kind to precipitate the move.
Since joining the Boston organization in the middle of last month, Belisario has thrown 6 1/3 scoreless innings, allowing just four hits but permitting three walks to go with his two strikeouts. But the results have been there all year at the Triple-A level. Including his time in the Rays organization, Belisario has tossed 36 2/3 frames of 2.70 ERA baseball at the minors’ highest level.
Belisario was somewhat less productive in a brief stint with Tampa Bay earlier in the year, allowing seven earned runs in eight frames. More concerning, perhaps, is that he showed a marked decreased in velocity. After averaging better than 94 mph on his fastball for his career, Belisario showed a sub-92 mph offering with the Rays.
While he also struggled to keep runs off the board last year for the White Sox, and has not posted above-average run prevention numbers since 2012, Belisario continues to fare well in the eyes of ERA estimators. He carries a lifetime 3.26 SIERA and has never ended a MLB season with a mark of over 3.46 in that metric.
It stands to reason that another organization will give the veteran a shot, particularly with the trade market now complicated by the need to pass players through waivers.
