Pete Alonso didn’t flip his bat after he tied the game in the ninth inning Tuesday with his 300th homer. He threw it and shouted and after he circled the bases to Citi Field cheers and “Fire Stearns” chants he took a curtain call.

“It’s just crazy, how things kind of unfolded,” starter Sean Manaea (two earned runs, 5 1/3 innings) said after the Mets (69-82) lost 7-5 in 11 innings in front of 28,097. “I’ve got nothing but respect for him and I love him to death, but as the team, as the 2026 Mets – I know we’ve definitely under-performed – the guys in here work their ass off every single day.

“And to have that kind of reaction to an opposing player – could be anybody – is crazy. I’ve got nothing but respect for Pete but I’ve just never seen anything like that before and I know the guys in here, we are grinding our butts off.”

Alonso hit his 36th homer of the season 414 feet off Kodai Senga, who was asked if the fan reaction bothered him. It was the newly installed closer’s first blown save. He entered the game 7-for-7.

“Perhaps if it was another hitter,” he said through a Japanese interpreter. “If it wasn’t Pete Alonso. There are other great hitters that have played for the Mets that are playing elsewhere. But because it was him, it didn’t bother me. It just shows how much he was loved, it just shows how great of a hitter he is and how much he meant to this organization.”

“You don’t choose your circumstances in life,” Andy Green said. “You choose your character and how you respond to circumstances. So (fans are) free to do whatever they want to do on the field. Our job is to never let anything external impact the way we go about playing the game.

“Do we love our fans cheering for us? Heck yeah, we do. Do we want our fans engaged with us? Heck yeah, we do. We absolutely want that. We understand that we didn’t meet expectations this season. We’ll show up tomorrow, play to win a baseball game.”

Three fans who caught the ball traded it with Alonso after the game for signed baseballs and bats. He signed their jerseys, too, and got them beers. Two were in Alonso jerseys and one was in a Carlos Delgado jersey. Alonso offered them tickets to a game at Camden Yards.

“I appreciate all the support, especially for all the years I’m here, all the life I’ve lived here,” Alonso said. “It’s a two-way street.”
