Rea is not listed among the Brewers' probable starters for their upcoming series versus the Diamondbacks and could be shifted to a relief role ahead of the postseason, Adam McCalvy of MLB.com reports.

Rea's last start came Sept. 11, when he was blasted for 10 runs over four innings in a loss to the Giants. He then threw 2.2 scoreless innings out of the bullpen to pick up a save in Monday's win over the Phillies. The Brewers don't currently have a starter listed for Friday, and it's possible Rea will wind up taking the ball that day on three days' rest. Even if he gets another start or two down the stretch, Rea looks on track to fill a relief role during the postseason. He's posted a 6.82 ERA over his last seven appearances (six starts).
