Dollander is slated to work as a bulk reliever behind an opener in Tuesday's game against the Padres, Patrick Saunders of The Denver Post reports.
Dollander was also deployed out of the bullpen to follow an opener during his most recent outing in Thursday's 3-2 victory over the Astros. The approach worked well for the right-hander, who picked up the win after firing 5.1 scoreless frames while striking out nine.
