Harper, Espinosa help Nats down Padres

San Diego, CA (SportsNetwork.com) - Bryce Harper and Danny Espinosa each hit a three-run home run on Sunday as the Washington Nationals wrapped up a four- game set against the San Diego Padres with a 10-5 win.

Harper finished 3-for-4 with four RBI and three runs scored while Tyler Moore drove in two for the Nationals, who have won nine of their last 11. Stephen Strasburg (3-4) allowed three runs on five hits with a walk and seven strikeouts in five-plus innings.

"The biggest thing is to stay focused and find the positive in every outing," said Strasburg. "Try to keep going in the right direction."

Justin Upton hit a pair of solo home runs and Jedd Gyorko also homered for the Padres, who have dropped five of their last seven. Ian Kennedy (2-3) gave up six runs on three hits with four walks in five-plus innings.

"It's been a grind for us the last couple of weeks," said Upton. "We have to get back to what we did early in the year and that's playing as a team."

Matt Kemp singled home a run in the first and Upton hit a solo homer in the third to stake the Padres to a 2-0 lead.

Washington, though, went on top in the fifth when Espinosa hit his three-run blast over the wall in right for a 3-2 advantage.

The Nationals padded their advantage in the sixth as Harper singled home one and Ryan Zimmerman's sac fly brought in another before Moore punched a two-run double for a 7-2 lead.

Yangervis Solarte scored a run on a fielder's choice in the San Diego sixth to make it a four-run game, but Harper countered with a three-run home run in the seventh to make it a 10-3 contest.
