Manny Machado lit up the scoreboard all night and Matt Wieters contributed a late three-run homer to help the Orioles slug their way past the Nationals, 10-8, at Nationals Park on Wednesday night. Both Wieters and Machado — who finished with four hits, including his 29th homer — drove in four runs in support of left-handed starter Wade Miley, who was acquired by Baltimore last month and earned his first win as an Oriole with five-plus innings of two-run ball.
