Pirates sent RHP Yerry De Los Santos outright to Triple-A Indianapolis.
De Los Santos will remain with the Pirates, if he winds up going unclaimed on waivers, but has been removed from Pittsburgh’s 40-man roster heading into the offseason. The 25-year-old righty made 22 relief appearances last season in the big leagues, finishing with a respectable 3.33 ERA, 1.23 WHIP and 18/13 K/BB ratio across 24 1/3 innings of work.
