Nationals' Bryce Harper among 4 starters out against Padres

WASHINGTON -- National League home run leader Bryce Harper is among four starters out of the lineup for the Washington Nationals in their series finale against the San Diego Padres on Sunday.

Daniel Murphy, Jayson Werth and Matt Wieters also did not start for the Nationals, who open a nine-game, 10-day road trip Monday afternoon in San Francisco.

Murphy missed the previous two games due to illness, Chris Speier said Saturday. Speier, serving as acting manager with Dusty Baker away this weekend to attend his son Darren's high school graduation in California, did not meet with the media before Sunday's game.

Harper is batting .337 with 15 home runs and 41 RBI.

Washington won the first two matchups in the three-game series.

Joe Ross (2-0, 5.32) faces fellow right-hander Jhoulys Chacin (4-4, 5.74) on Sunday.
