Pete Alonso smashes grand slam as Mets bats break out in destruction of Marlins

MIAMI — The torpedo doors remained shut, but Pete Alonso had little trouble sinking the enemy fleet Monday night. 

Alonso, who before the game told The Post he doesn’t use the innovative torpedo bat that has become the buzz of MLB following the Yankees homer barrage over the weekend — but will “probably order some and try them out” — got the Mets resembling a destructive force for the first time this season. 

Alonso’s grand slam was one of four homers hit by the Mets in a 10-4 demolition of the Marlins at loanDepot park. 

After three frustrating offensive games in Houston, where they managed only five runs total and lost twice, the Mets jumped all over right-hander Cal Quantrill in the fifth inning and coasted. 

The Mets first baseman was asked if there is a special feeling to hitting his first homer in a season. 

“It’s a long time without hitting one and to finally do it in a big league game, it feels pretty cool,” Alonso said. “I can do it still.”
