Jordan Zimmermann, an all-star, takes the mound against the Phillies, aiming for his 13th win. Zimmermann (12-3, 2.57 ERA) would Max Scherzer of the Tigers and Matt Moore of the Rays for the major league lead. Kyle Kendrick (7-6, 3.90 ERA) has been hit well by the Nationals, who have scored six runs in 12 2/3 innings over two starts this season. The lineups are here. As always, discuss the game here.
