Jhoulys Chacin posted a 3.48 ERA, 1.30 WHIP and 7.8 K/9 in 333-plus innings between 2010-2011, becoming one of the only reliable members of an ever-fluctuating Colorado starting rotation. But the good times have suddenly come to a screeching halt for the 24-year-old Rockies right-hander.
Chacin allowed 11 hits and seven earned runs in 4 2/3 innings Tuesday night against the Dodgers and was demoted to Triple-A Colorado Springs on Wednesday night as the owner of a 7.30 ERA, 1.86 WHIP and 22/15 K/BB ratio through five starts.
The Rockies are expected to make a corresponding roster move before Friday’s game and will need to name a new starter by Monday. Jeremy Guthrie is still at least a week away from returning from a sprained right shoulder, so Colorado may look to prospect Alex White to fill the now-vacant rotation spot.
Chacin will presumably be brought back quickly if he begins having better results down on the farm.
