The Rays designated reliever Ronald Belisario for assignment after tonight’s game, the club told reporters including Marc Topkin of the Tampa Bay Times (via Twitter).
Tampa Bay recently decided to add the 32-year-old to its big league roster when he exercised an opt-out clause in his minor league deal. Since that time, Belisario has thrown eight innings for the club — including his appearance tonight — and allowed seven earned runs. He has compiled six strikeouts against four walks on the year.
Belisario was throwing rather well in Triple-A, sporting a 3.26 ERA with 5.3 K/9 against 2.7 BB/9 over 30 1/3 frames. And he’s had success in the big leagues in the past. But clubs considering Belisario will surely note that his fastball velocity (in his few big league outings this year) was down about two miles per hour from recent seasons.
