Revamped top of lineup powers Bucs past Nats

Gregory Polanco and new leadoff hitter Corey Dickerson combined to score four times and drive in five, and Ivan Nova battled through 5 2/3 to earn the win. Juan Soto and Bryce Harper homered for Washington, and prospect Jefry Rodriguez rebounded from a rough opening two frames to give the Nats five solid innings. But Felipe Vazquez squelched a ninth-inning rally to seal the series opener for Pittsburgh.
