WASHINGTON (Interstat) — Brandon Marsh homered and drove in three runs, Bryce Harper added a homer and three RBIs, and the Philadelphia Phillies erased an early four-run deficit to beat the Washington Nationals 10-5 on Thursday night at Nationals Park.

The Phillies trailed 4-0 after the first inning but rallied behind a balanced attack that included 13 hits, a strong bullpen performance and a five-run ninth inning that put the game out of reach. Philadelphia improved to 45-36 with the victory, taking three of four games in the series, while Washington fell to 41-41.

Washington struck quickly against Phillies starter Cristopher Sánchez. Curtis Mead opened the bottom of the first with a solo home run, his 14th of the season, to left-center field. After Andrés Chaparro was hit by a pitch, Dylan Crews and Daylen Lile strung together consecutive singles, with Lile’s hit scoring Chaparro. Jacob Young then grounded out to drive in Crews, and Nasim Nuñez singled to bring home Lile, giving the Nationals a 4-0 lead.

Sánchez settled in after the rocky first but allowed another run in the third. Crews singled and scored on a two-out single by Young that deflected off second baseman Bryson Stott, extending Washington’s lead to 5-0. Sánchez finished five innings, allowing five runs on seven hits with six strikeouts and one walk.

Washington starter Cade Cavalli, meanwhile, kept Philadelphia scoreless through the first five innings. He allowed only two hits and struck out seven over the first five, but the Phillies broke through in the sixth.

With one out, Harper singled and Marsh followed by hitting his 12th homer of the season to right-center, cutting Washington’s lead to 5-2. Cavalli departed after six innings, having allowed two runs on five hits with seven strikeouts and two walks. The Nationals turned to reliever Gus Varland in the seventh, and the Phillies immediately pounced.

Justin Crawford led off with a single, and Trea Turner followed with a sharp single to right. Kyle Schwarber walked to load the bases, and Harper walked to force in Crawford. Marsh then walked to force in Turner, tying the game at 5. Alec Bohm grounded into a forceout that scored Schwarber, giving the Phillies a 6-5 lead. Bryson Stott walked, but J.T. Realmuto grounded out to end the inning. Varland took the loss, falling to 0-2.

Philadelphia’s bullpen took over from there. Chase Shugart pitched a scoreless sixth, striking out two. José Alvarado followed with a scoreless seventh, also striking out two. Orion Kerkering worked a scoreless eighth, allowing one hit and striking out two. Kerkering was credited with the win and improved to 5-0. Tim Mayza pitched a perfect ninth.

The Phillies broke the game open in the top of the ninth. With one out, Harper hit his 18th home run of the season to left field, scoring pinch-runner Garrett Stubbs and making it 8-5. Marsh followed with a single, and after a flyout, Realmuto doubled to left-center to drive in Marsh. Derek Hill then capped the inning with a two-run homer to left-center, his sixth of the season, giving the Phillies a 10-5 lead.

Hill, who entered as a pinch hitter and stayed in right field, finished 2 for 3 with a homer and two RBIs. Harper was 2 for 3 with a homer, a walk and three RBIs. Marsh went 2 for 4 with a homer, three RBIs and a walk, continuing a hot stretch in which he had collected multiple hits in three of his previous four games.
