PHILADELPHIA (AP) - Roberto Hernandez pitched four-hit ball over 7 1-3 innings, outdueling Gio Gonzalez and leading the Philadelphia Phillies past the Washington Nationals 1-0 Sunday.
Chase Utley hit an RBI single in the first inning for the only run.
Hernandez (2-1) struck out three and walked three. His start was moved up two days because Cole Hamels had the flu, and he retired 14 of 15 batters in the middle innings.
Mike Adams and Antonio Bastardo each got an out in the eighth. Jonathan Papelbon pitched the ninth for his ninth save in 10 chances.
Gonzalez (3-2) allowed four hits in 7 1-3 innings. He struck out seven and walked two.
Philadelphia scored when Jimmy Rollins hit a one-out triple and Utley followed with a single.
Ben Revere tripled with one out in the Philadelphia third, and Gonzalez didn't give up another hit until Jayson Nix's leadoff single in the eighth.
Gonzalez got some help from his defense during that stretch, as Nate McLouth robbed Rollins of a hit with a diving catch in left field to open the sixth.
The slumping McLouth didn't have success with the bat, though, going 0 for 3. He has just four hits in his last 44 at-bats, and has been filling in for the injured Bryce Harper.
Denard Span opened the eighth with a single off Hernandez and the Philadelphia starter departed after Kevin Frandsen's sacrifice bunt.
Adams, who gave up the lead and took the loss in Friday night's series-opening loss to the Nationals, got Jayson Werth to ground out. Bastardo then relieved and walked Adam LaRoche before striking out Anthony Rendon.
The Phillies unsuccessfully challenged a safe call by first-base umpire Fieldin Culbreth in the second. Culbreth ruled that Ian Desmond beat Rollins' throw from shortstop to first baseman Ryan Howard. The delay lasted 2 minutes, 42 seconds.
