The Nationals enter Monday in the best of spirits: a six-game winning streak, a season-high 16 games over .500 and a six-game division lead. And with the Dodgers’ loss on Sunday night, the Nationals now have the best winning percentage (.566) in the NL. Jordan Zimmermann (8-5, 2.92 ERA) is 2-0 with a 1.37 ERA in August so far. Left-hander Vidal Nuno (0-3, 3.92 ERA), acquired in the Brandon McCarthy trade, starts for Arizona. The lineups are here. As always, discuss the game below.
