Suter has been told to prepare for relief duty, Tom Haudricourt of the Milwaukee Journal Sentinel reports.
Making his big-league debut Friday, Suter gave up four runs on seven hits (including two home runs) and three walks over 4.1 innings in a loss to the Mariners. The Brewers will keep him around rather than send him back to Colorado Springs but Suter will transition to a long-relief role, with the potential to make a couple spot starts over the season's final month. It's uncertain who will take his spot in the rotation.
