Nolin will start Sunday's game against the Brewers, Jesse Dougherty of The Washington Post reports.
Nolin took the loss in the first game of an Aug. 12 doubleheader against the Mets, allowing four runs on eight hits across three innings. Despite the underwhelming outing, the left-hander will get another opportunity to earn his second career big-league win Sunday. Manager Dave Martinez wouldn't commit to Nolin taking Joe Ross' (elbow) rotation spot permanently, but that figures to be a possibility.
