The Nationals will stick with what’s working, which means Danny Espinosa will remain on the bench. Bryce Harper is still hitting sixth, with Anthony Rendon second against red-hot right-hander Jake Arrieta.

The Nationals are 6-1 in their last seven games, but over that span the Nationals have moved from a first-place tie to 1 1/2 games behind the Braves, who have won nine in row.
