Pete Alonso's wife Haley has goosebumps as she celebrates Slugger's epic Mets home run

Haley Alonso took it all in after her husband became a Mets legend.

Pete Alonso's three-run, ninth-inning home run against the Brewers gave the Mets a 4-2 win in Game 3 of their Wild Card Series and saved a season that lasted just two outs from ending.

On her Instagram Story, Haley posted a video of Alonso's home run with the Mets trailing 2-0.

“CRAZY!!!!!!” she wrote.

Haley added “CHILLS” on a separate slide that replayed the home run with Mets radio voice Howie Rose in conversation, who yelled, “He did it! Pete Alonso with the most memorable home run of his career!”

She also shared a photo of Alonso and Mets manager Carlos Mendoza celebrating together after the win.

“Mendy & Pete,” she wrote, adding a pair of teary-eyed emojis.

Alonso's momentous blast at American Family Field was unlikely for many reasons.

It came against Milwaukee's closer Devin Williams, who is one of the best in the game, and Alonso was in a slump.

The slugger hadn't had an extra-base hit in two weeks.

Just an inning earlier, he had dropped a foul pop-up that fortunately didn't increase the Mets' deficit to more than two runs.

“I wanted to be in this position,” Alonso said afterwards. “I wanted to do something for my team. I want to make a positive contribution.”

Haley had her own part in the team's success as Pete showed off the Mets' playoff pumpkin, which the first baseman said he picked out with his wife.

The home run and win extend Alonso's career with the Mets by at least a few more games, as the team now faces the rival Phillies in the NLDS starting Saturday in Philadelphia.

The 29-year-old Alonso enters free agency having given himself a huge negotiating advantage no matter how the rest of the offseason plays out.

Mets owner Steve Cohen was thrilled as he was in the locker room where players danced under champagne showers.

“It’s just a storybook script. A Hollywood writer couldn’t write it better,” he said.
