The Pirates will begin their final series of the season on Friday night, when right-hander Mitch Keller takes the mound against Cleveland at Progressive Field. Keller pitched six hitless innings in his last outing, showing the top-of-the-rotation potential that made him the organization’s top prospect entering the year. Right-hander Carlos Carrasco will start for the Indians. First pitch is set for 7:10 p.m. ET, and the action will be live on MLB.TV.
