WASHINGTON -- Bryce Harper hit his second walk-off home run of the season as the Washington Nationals beat the Phillies, 6-4, Saturday night.
Harper hit a 0-1 fastball from Edubray Ramos for a two-out, two-run homer. The pitch was 95 mph. It left the park at 110 mph.
Earlier in the day, Harper signed a contract for 2018 worth $21 million (see story).
Harper also beat the Phils with a walk-off homer on April 16.
The Phillies led 4-0 heading into the bottom of the fifth inning, but they could not hold it. It was the third time in three games that they blew a four-run lead. They blew two of them in Tuesday night's loss to Seattle.
The Phillies have lost 11 of their last 13. They have held a lead at one point in nine of those losses.
The Phils are 13-20.
The Nats are 23-12.
Starting pitching report
Nick Pivetta appeared to be on his way to his first major league win. He took a 4-0 lead into the bottom of the fifth but failed to get out of the inning. He gave up three extra-base hits and four two-out runs in the inning as the Nats tied the game.
Washington starter Tanner Roark gave up six hits, three walks and four runs in 4 2/3 innings. The walks really hurt him as two of them became runs and all four of the runs he gave up came after he had extended an inning with a two-out walk.
Roark had dominated the Phillies in his previous seven starts against them, dating to the start of last season. He had allowed just five earned runs in 47 innings over that span.
Bullpen report
Luis Garcia, Joely Rodriguez, Pat Neshek, Joaquin Benoit pitched scoreless ball before Ramos gave it up in the ninth.
The Nats' bullpen picked up 4 1/3 scoreless innings.
At the plate
Michael Saunders had an RBI single in the fourth and Cameron Rupp added a two-run single in the inning. The Phils went up 4-0 on Tommy Joseph's RBI double in the fifth.
The Nats scored four two-out runs in fifth, two on a homer by Trea Turner and two on a double by Ryan Zimmerman. Both of those hits came against Pivetta fastballs.
All six of the Nats' runs came with two outs.
Maikel Franco was dropped from fourth to sixth in the batting order. He extended his slump to 0 for 16 when he hit into a double play in the second inning. He singled in the fourth inning.
Odubel Herrera struck out three times en route to an 0 for 5 night.
Nola update
Aaron Nola has recovered from his strained lower back. He will make his second minor-league rehab start Monday night in Rochester, New York, for Triple A Lehigh Valley. Team officials are looking for him to get to about 80 pitches. He could return to the big-league rotation as soon as next weekend.
