Werth, Zimmerman homer as Nationals defeat Padres 4-2

Upton Jr. snags a ball backward

Padres center fielder Melvin Upton Jr. mimics Willie Mays' famous play by making a backward catch for the final out in the bottom of the first inning against the Nationals.

WASHINGTON -- Jayson Werth and Ryan Zimmerman homered, and starter Joe Ross allowed only a bunt single in six innings as the Washington Nationals beat the San Diego Padres 4-2 on Thursday night.

Zimmerman went 2 for 4 with two RBI. His run-scoring single in the fifth gave the Nationals the lead for good at 2-1.

Werth, who went 2 for 4, added a solo homer off San Diego starter Andrew Cashner (5-13) in the sixth. Zimmerman greeted reliever Kevin Quakenbush with a homer to start the seventh.

Zimmerman finished the series with eight RBI in three games.

Ross (5-5) won his second straight start, allowing the bunt single by Corey Spangenberg and one run in six innings. The right-hander struck out seven and walked two.

Jonathan Papelbon closed it in the ninth with his fourth save since joining Washington despite giving up a run on Yonder Alonso's two-out single.
