Alec Bohm hit a three-run homer to cap a six-run fourth inning Friday night for the visiting Philadelphia Phillies, who clinched a playoff berth by beating the New York Mets 12-2 in the second game of a four-game series.

Bohm finished 4-for-5 with four RBIs for the Phillies (92-62), who have reached the postseason for the third straight year. Philadelphia’s magic number for clinching the National League East for the first time since 2011 is two.

The Phillies scored the final 12 runs Friday to cool off the red-hot Mets (85-69), who had their four-game winning streak snapped but remained two games ahead of the Atlanta Braves in the race for the third and final N.L. wild-card spot. The Braves fell to the Miami Marlins, 4-3, on Friday.

Edmundo Sosa began the comeback with a second-inning sacrifice fly and Nick Castellanos tied the game with an RBI double in the third. The Phillies chased David Peterson (9-3) in the fourth, when Johan Rojas laced a two-run double, and Trea Turner greeted Adam Ottavino with an RBI single two batters before Bohm’s blast.

Bohm and Castellanos had RBIs in the sixth and J.T. Realmuto hit a two-run homer in the eighth.

Every Phillies starter had at least one hit. Castellanos collected three hits while Realmuto, Rojas and Turner had two hits apiece.

Cristopher Sanchez (11-9) earned the win after allowing two runs on three hits and five walks while striking out seven over five innings. He gave up both runs in the first, when Jose Iglesias hit his first career leadoff homer and Brandon Nimmo hit into an RBI groundout.

The Mets had just one hit — Iglesias’ fifth-inning double — the rest of the way. Iglesias is hitting .476 (10-for-21) in the last five games as New York’s leadoff hitter in place of the injured Francisco Lindor. Iglesias also has a 14-game hitting streak.

Peterson gave up five runs (four earned) on eight hits and no walks, striking out four over a season-low 3 2/3 innings. Infielder Eddy Alvarez made his big-league pitching debut by tossing a scoreless ninth.
