Every game for the remainder of the NLCS could potentially be Pete Alonso's last game with the Mets, but the impending free agent clearly has no intention of leaving quietly, if at all.

Alonso's four runs scored Friday night were highlighted by a mammoth three-run home run in the first inning in what turned out to be a season-extending 12-6 win over the Dodgers in Game 5 of the NLCS.

Just as Francisco Lindor had hit a leadoff home run in the first inning of Game 2 to ignite the Mets' previous victory, Alonso hit a three-run blast over the wall in center off Dodgers righty Jack Flaherty on Friday night to score one early lead.

Lindor and Brandon Nimmo scored off Alonso after each reaching a single and a walk.

It was a first step in the right direction for the Mets after the Dodgers secured a 3-1 series lead with a 10-2 loss the night before.

It was Alonso's fourth home run of the postseason, tying Mark Vientos for the team lead, but it was his first in six appearances since Game 3 against the Phillies in the NL Division Series.

The home run also snapped the Mets' collective 0-for-17 skid with runners in scoring position.

Alonso came into the game batting .133 (2-for-15) in the first four games of the series, with no extra-base hits or RBIs.

The four-time All-Star also walked and scored five runs in the Mets' third inning, and an inning later he scored a third time in the game after being plunked by Dodgers reliever Brent Honeywell.

Alonso added a bloop single to center in the eighth and scored on Starling Marte's RBI single – his fourth hit of the game – for a 12-6 lead that held.
