Right-hander Ronald Belisario has elected free agency rather than accepting an outright assignment to Triple-A, MLB.com’s Scott Merkin tweeted earlier today.
Belisario, 32 on New Year’s Eve, pitched 66 1/3 innings for the White Sox in 2014, though he struggled to a 5.56 ERA with a below-average mark of 6.4 K/9. However, Belisario also posted a strong 2.4 BB/9 with an outstanding 59.3 percent ground-ball rate, leading metrics such as FIP (3.54) and SIERA (3.22) to feel that he was experienced some particularly poor luck. He did see his BABIP spike to a career-worst .339, and his 57.7 percent strand rate was well below both the league average and his career mark (69.9%).
Belisario has been a fixture in a big league bullpen in each of the past three seasons, averaging 68 innings per year with the White Sox and Dodgers. FIP and xFIP have graded him pretty consistently throughout his career and both feel he’s capable of an ERA in the 3.60 range, while SIERA (3.22) is a bit more bullish.
