WASHINGTON -- Anthony Rendon homered twice and drove in five runs, Joe Ross returned from the minors to allow one run over a career high-tying eight innings, and the Washington Nationals routed the Seattle Mariners 10-1 on Tuesday night.
Bryce Harper added his 14th homer and Jayson Werth hit his seventh off Chris Bergman (1-2), who allowed all of the Nationals' runs and 14 of their 15 hits.
Rendon doubled before his second homer -- and seventh of the season -- completed an eight-run fourth inning.
