Miller will rejoin the Mariners rotation Wednesday in Boston after Emerson Hancock (adductor) was placed on the 15-day injured list Sunday, Daniel Kramer of MLB.com reports.
After manager Dan Wilson announced last week that the righty would be demoted to the bullpen, Miller didn't end up making any relief appearances and will now be plugged back into the five-man rotation while Hancock is out. Miller has posted a 7.18 ERA and 27:16 K:BB across 36.1 frames since the All-Star break.
