Ross Detwiler (2-0, 0.69 ERA) has been perhaps the most impressive Nationals pitcher this season. In two starts, over 13 innings, he has allowed one run and 10 hits. He makes his third start of the season in the rubber match of a series against the Marlins in Miami. He is opposed by Ricky Nolasco (0-1, 3.12 ERA), the Marlins No. 1 starter. Bryce Harper returns to the lineup, while Denard Span and Danny Espinosa rest with illness and injury, respectively. The lineups are here. As always, talk about the game here.
