CBS Sports has confirmed a report from Chris Cotillo of The Springfield Republican that veteran reliever Hector Rondon has decided to retire. Rondon, 33, signed a MiLB deal with the Boston Red Sox back on April 3 but had not pitched a game in Boston this year. He wraps up an eight-year career as a reliever in which he pitched to a 3.49 ERA, 3.63 FIP, 1.2 WHIP, 9.1 K/9 and 4.6 fWAR in 444 appearances – largely as a member of the Chicago Cubs.
He was a key part of the Chicago bullpen for several years, including the 2015 and 2016 seasons.
