Manager Craig Counsell said Suter will start Friday's series opener in Miami, Adam McCalvy of MLB.com reports.
Milwaukee plans to treat the first game of its series with the Marlins as a bullpen day, so Suter shouldn't be expected to work much more than two or three innings in the start. Suter has been one of Milwaukee's most reliable relievers this season, submitting a 2.70 ERA while striking out 15 in 16.2 innings.
