Rea will start Friday's game versus the Diamondbacks, Adam McCalvy of MLB.com reports.

Rea's last appearance came in relief Monday, and since the Brewers previously hadn't committed to a starter for Friday, the right-hander looked like he could end up sticking in the bullpen for the rest of the season. Milwaukee will ultimately turn to Rea to fill the fifth spot in the rotation on three days' rest, though he's still likely on the outside looking in for a starting role during the postseason. Rea holds a 6.82 ERA over his last seven appearances (six starts).
