The Colorado Rockies on Friday optioned right-handed pitcher Eddie Butler to Triple-A Albuquerque and placed left-handed reliever Boone Logan on the 15-day disabled list, according to MLB.com's Dargan Southard.
Relievers Ken Roberts and Gonzalez Germen were recalled from Albuquerque in corresponding moves.
Butler on Thursday continued a string of poor starts at the major league level, allowing six runs on seven hits in four innings in a 12-3 loss to the New York Mets.
