Bryce Harper hit a three-run home run and J.T. Realmuto had three hits to lead the Philadelphia Phillies to a 5-4 victory over the visiting San Francisco Giants on Sunday night.

Alec Bohm doubled in the seventh inning to extend his hitting streak to 18 games for the Phillies, who won their fifth straight game and ninth in the past 10. Philadelphia has won the first three contests of the four-game series and owns the best record in baseball at 24-11.

Jose Alvarado served up Jakson Reetz's first major league homer with one out in the ninth before striking out Nick Ahmed and retiring Jung Hoo Lee on a fly to right for his seventh save.

Thairo Estrada smacked a two-run homer for the Giants, who have lost five of their past six games. Michael Conforto doubled and tripled in four at-bats.

Taijuan Walker (2-0) gave up three runs and five hits over 6 1/3 innings for the Phillies. He struck out seven and walked one.

San Francisco ace Logan Webb (3-3) allowed five runs (four earned) and six hits over four innings. He struck out six and walked two.

Harper's big blow highlighted a four-run uprising in the bottom of the third as Philadelphia won its ninth straight home game.

Schwarber walked and Realmuto singled off Webb to start the frame. Harper then stepped into the box and sent a 1-1 changeup 410 feet over the wall in right center to give the Phillies a 4-1 lead. It was his seventh blast of the season.

Two outs later, Nick Castellanos singled, stole second and scored on Bryson Stott's run-scoring double to left.

The score remained 5-1 until Walker tired in the seventh.

After Mike Yastrzemski reached on an infield single with one out, Estrada jumped all over a 1-0 sinker and drilled a two-run homer to end Walker's night. The 401-foot blast was Estrada's fifth of the season.

San Francisco scored in the first when LaMonte Wade Jr. singled with one out and Conforto slugged a two-out RBI double off the fence in left.

Philadelphia knotted the game in the second inning when Edmundo Sosa came up with two on and two out and reached on a broken-bat single to score Bohm. The bat sailed to the left of Webb, preventing him from trying to stop the ball.
