Yonder Alonso also homered for the second time in as many days, going back-to-back with Healy in the seventh for his ongoing career-high 16th of the season, a two-run shot. Healy has 11 on the year, giving the A's three players with double-digit home runs (Khris Davis, 16).
The A's struck for a combined seven runs in the first three innings against Nationals right-hander Joe Ross, who didn't return for the fourth after 82 pitches. Oakland starter Daniel Mengden's day was also cut short, after just 4 2/3 innings. The right-hander allowed four runs on six hits, including a three-run homer to Adam Lind in the third.
