As good as Josiah Gray was early in the season, he has lost his way in August and September, with just one quality start in his last six appearances. He has averaged nearly a run an inning, lasting just three or four innings per appearance lately. He has struggled when pitching on the road this season. He will face the Pirates' Keller who was crushed in his last start vs Atlanta, but has otherwise been solid, allowing three runs or less in his previous five starts. Keller is a good bet to bounce back, especially when pitching at home. The Nationals are just 3-7 in September. They lost their home part of back to back series and now face the Pirates at home. Washington is struggling on offense (29th, .225 BA, .650 OPS) in the last two weeks. Another short start from Gray will expose their unproductive bullpen. The Pirates are above .500 in September, and hitting better for average and power. Look for continued strong work from Keller and a third straight victory from the Pirates.
