PHILADELPHIA — Zack Wheeler struck out 11 in seven innings, Bryce Harper hit a three-run homer, and Kyle Schwarber added a solo shot to help the Philadelphia Phillies complete a four-game sweep of the San Francisco Giants with a 6-1 win on Monday.

The major league-leading Phillies (25-11) won their sixth straight and have won 10 of 11 and 17 of 20 to open a three-game lead over Atlanta in the NL East.

The Phillies have also won 10 straight games at Citizens Bank Park, just two wins shy of matching the team record set in 2012. Philadelphia also set a franchise record with 11 straight wins against NL West opponents.

Meanwhile, the Giants have lost four straight and six of their last seven games. They’re 6-14 on the road and 15-21 overall — eight games behind the first-place Los Angeles Dodgers in the NL West.

Up Next

The Giants stay on the road with three games at Colorado starting Tuesday. The Giants send LHP Kyle Harrison (2-1, 3.79 ERA) to the mound against Rockies RHP Dakota Hudson (0-5, 5.93).

The Phillies open a two-game set against Toronto on Tuesday. They will send LHP Cristopher Sánchez (1-3, 3.68) to the mound against Blue Jays RHP José Berríos (4-2, 1.44).

Harper’s Performance

Harper homered for the second straight game and his eighth of the season made it 4-0 against Giants rookie Mason Black (0-1). Black made his major league debut in front of his parents, younger brother, girlfriend, and scores of friends and relatives who made the trip to watch him pitch against his boyhood favorite team.

The 24-year-old Black — named the seventh-best prospect in baseball, per MLB.com — was the Giants’ third-round pick in the 2021 draft out of Lehigh University. Black recorded a 1-2-3 first inning that included strikeouts of J.T. Realmuto and Harper, the latter caught looking at an 88 mph changeup.

Black gave up eight hits, five runs and three walks. He struck out four in 4 1/3 innings.

Wheeler’s Dominance

Wheeler (4-3) showed the rookie how it was done. He rebounded from an 0-3 start — he allowed six runs total in his first three starts — to win his fourth straight start. Wheeler allowed one run, walked one and lowered his ERA to 1.62.

Matt Strahm tossed a scoreless eighth and Orion Kerkering pitched the ninth to complete the five-hitter.

Team Effort

With shortstop Trea Turner out at least six weeks with a left hamstring strain, his replacements are starting to fill the void. Bryson Stott moved from second base to shortstop and made a great grab on a grounder by Wilmer Flores in the first to start an inning-ending double play. Whit Merrifield started at second and gave the Phillies a 1-0 lead with an RBI single in the fourth.

Harper had a three-run shot in the fifth and Nick Castellanos, who hit 37 doubles last season, hit his first one of the year later in the inning for a 5-0 lead.

Phillies third baseman Alec Bohm went 0 for 4, ending his hitting streak at 18 games.
