Priester is expected to pitch behind opener DL Hall in Friday's game against the Nationals, Adam McCalvy of MLB.com reports.
The right-hander has worked as a traditional starter in 12 of his 16 appearances this season, but he'll piggyback Hall in his final appearance before the All-Star break. Priester has been a quality back-end rotation piece for the Brewers during the first half with a 3.59 ERA, 1.27 WHIP and 65:30 K:BB across 82.2 innings, but he could lose his spot when Nestor Cortes (elbow) is ready to return.
