Mookie Betts homered twice on a night he was originally supposed to have off, and the Los Angeles Dodgers beat the Washington Nationals 9-4 Tuesday night. Betts smacked a three-run homer off former Dodgers prospect Josiah Gray and hit solo shot off Victor Arano for his 21st career multi-homer game and his second of the season. "Over the last 30 days, it's as good as anybody on the planet right now," manager Dave Roberts said.
