New York (86-69) won for the 17th time in 22 games. The Mets began the day two games ahead of Atlanta for the final NL wild card and one game behind Arizona, which was in the second wild-card position.

A crowd of 44,152 filled Citi Field, just the fourth sellout this season after opening day and a pair of Subway Series games against the Yankees.

Philadelphia (92-63), which has lost two of the first three games of the four-game series, can secure its first NL East title since 2011 with a victory over the Mets on Sunday night.

Manaea (12-5) retired 21 of 24 batters, allowing Kyle Schwarber’s record 15th leadoff home run of the season, Nick Castellanos’ tying homer in the fifth and J.T. Realmuto’s leadoff single in the eighth. The 32-year-old left-hander never pitched from the stretch, allowing three runs and three hits in seven-plus innings while striking out six. Manaea lasted at least 6 2/3 innings for the eighth straight start.

Cal Stevenson’s RBI grounder off Reed Garrett in the eighth pulled the Phillies within two runs. Díaz threw a called third strike past Schwarber on a full-count fastball and finished for his 19th save in 25 chances, his third four-out save this season.

With the score 2-all, Kerkering walked Starling Marte leading off the seventh and with one out hit Pete Alonso on the left shoulder blade with a 97 mph pitch.

Nimmo lofted a single into left-center for a 3-2 lead, ending the Mets’ 0-for-14 streak with runners in scoring position. Nimmo stole second and Alvarez doubled just beyond the glove of left fielder Weston Wilson, who tried for a diving catch.

Alvarez has 12 RBIs in his last eight games. He hit a 113.8 mph drive for his 11th home run this season and fifth in nine games. Acuña’s homer was the third in his first 24 big league at-bats.

Alonso added an RBI single in the eighth when his two-out pop fly to short center fell between Stevenson and second baseman Bryson Stott, who each thought the other would catch the ball.

Phillies starter Ranger Suárez allowed five hits and three walks in five innings.

New York benched J.D. Martinez, in a career-worst 0-for-31 slide. Mark Vientos stuck out a career-worst five times.

The Mets finished 5-5 this season in their new gray City Connect jerseys.
