PHILADELPHIA (AP) -- Max Scherzer didn't allow a hit until the sixth inning and he was dominant through eight as the Washington Nationals continued their mastery of the Philadelphia Phillies with a 3-2 victory Tuesday night.
Scherzer (15-7) allowed three hits and struck out 11 while walking one. He was perfect through the first four innings, striking out five consecutive batters -- all swinging -- between the second and third innings.
Ryan Howard, who got the start despite being 1 for 18 with 11 strikeouts against Scherzer coming in, hit an opposite-field two-run home run in the seventh inning to break up the shutout and pull the Phillies within 3-2.
But Scherzer closed the door from there, striking out three more in the seventh and eighth en route to his 15th win of the season.
Mark Melancon pitched a scoreless ninth for his 37th save, getting a strikeout and inducing a game-ending double play after issuing a leadoff walk.
Freddy Galvis and Odubel Herrera collected the only other hits for the Phillies, who have lost six of eight to fall 12 games below .500. They have dropped their last eight games to Washington, which matches the team record for consecutive losses vs. the Nationals/Expos franchise.
Scherzer, who pitched two no-hitters last season, didn't allow a runner to reach base until Phillies catcher Cameron Rupp walked with one out in the fifth. Galvis ripped a double to right-field to lead off the sixth to break up Scherzer's no-hit bid, but was picked off second base by Scherzer to end the scoring threat.
Scherzer has allowed just five hits in his last two starts after pitching a two-hit, eight-inning gem vs. Baltimore on Thursday. He's taken a no-hitter into the sixth in nine of his 61 all-time starts with the Nationals.
The Washington ace also had a sacrifice-bunt RBI in the fourth after Ryan Zimmerman walked and Danny Espinosa ripped a single. The inning ended when Espinoza was thrown out at the plate on a dart from Phillies right fielder Aaron Altherr with Espinoza colliding with Rupp on the play.
The Nationals staked Scherzer to an early lead in the first inning. With two outs and nobody on, Daniel Murphy doubled before scoring on a double by Bryce Harper, his 19th RBI in the last 19 games. Wilson Ramos brought Harper home with an RBI single to put the Nats ahead 2-0.
Phillies starter Jerad Eickhoff (9-13), who walked just six batters in his last eight starts coming in, issued three walks and allowed five hits and three earned runs through six innings.
Scherzer's double-digit strikeout game was the 12th of the season, setting a Nationals record. He improved his career record to 7-1 against the Phillies, including a 6-0 mark since he joined the Nats in 2015.
The Nationals, who opened their six-game road trip with a 4-0 victory over the Phillies on Monday, are 7-1 at Citizens Bank Park this season.
Phillies: Peter Bourjois missed his second straight game after getting hit in the left wrist by a pitch Sunday.
The Phillies and Nationals wrap up their three-game series Wednesday night with Philadelphia LHP Adam Morgan (1-8, 6.50) opposing LHP Gio Gonzalez (9-9, 4.25).
