Pete Alonso lined a three-run homer to key a four-run ninth-inning rally and lift the New York Mets to a 4-2 victory over the Milwaukee Brewers on Thursday in the decisive third game of a National League wild-card series.

The sixth-seeded Mets will open the NL Division Series on Saturday at Philadelphia. The second-seeded Phillies won of the NL East, finishing six games ahead of New York and the Atlanta Braves.

The Brewers, making their sixth playoff appearance in the last seven years, still haven't won a postseason series since reaching Game 7 of the NL Championship Series in 2018.

Francisco Lindor, who had the Mets' only two hits through eight innings, walked to open the ninth against Brewers closer Devin Williams, who saved 14 of 15 during the season and finished Milwaukee's 5-3 win in Game 2.

The Mets' comeback victory in the decisive Game 3 gave them their first playoff series win since claiming the NL pennant in 2015. (AFP/AP)
