After a rainout in Chicago on Wednesday, a day off Thursday and another day off Monday, Rockies manager Jim Tracy said pushing Rogers back is a move to keep the rest of the team's starters in their normal routines.
"Looking at certain guys waiting eight or nine days before they pitch, that doesn't make any sense," Tracy said.
Rogers will still be contributing on the mound. After the Rockies optioned right-hander Clayton Mortensen to Triple-A Colorado Springs on Friday to make room for utility man Alfredo Amezaga, Tracy said Rogers will work out of the bullpen until his next start.
"Obviously, moving Esmil to the bullpen between now and next Saturday continues to afford opportunity for him to pitch, and also keeps our bullpen right where I want it to be."
Rogers is 3-1 with a 6.33 ERA in four starts this season.
