Rea is starting Sunday's game against the Royals, Curt Hogg of the Milwaukee Journal Sentinel reports.
Eric Lauer was originally listed as the starter for Sunday's contest, but Lauer is moving to the bullpen for the foreseeable future. Rea has a 4.94 ERA and 22:11 K:BB in 27.1 innings over six appearances this season. The Royals represent a good chance to pick up a win, but there's certainly risk using Rea as a fantasy streamer over the weekend, especially with Lauer available as a long-relief option.
