Derek Norris hit a pair of three-run home runs to back Scott Kazmir's fifth win and the Oakland Athletics beat the Washington Nationals 9-1 on Sunday to complete a series sweep.

Both of Norris' home runs came on identical two-out, 3-0 pitches from Washington starter and former Oakland pitcher Gio Gonzalez. The two players were part of a 2011 trade between the teams.

Nick Punto added two hits and three RBIs while Brandon Moss singled twice and doubled. Oakland has won four straight since dropping five of six against Boston and Seattle.

Kazmir (5-1) bounced back from his first loss of the year to pitch seven scoreless innings while allowing only four hits. He struck out four and didn't walk a batter for the fourth time this season.
