Pete Alonso wasn't exaggerating -- he's seriously lucky to be alive today ... because video his wife just shared of his Sunday car crash shows the Mets star's truck was a mangled mess after being hit.
Haley Alonso posted the footage on her social media page Monday, revealing Pete's truck came to a halt on its side after it rolled over several times in a wild wreck in Tampa, Fla. over the weekend.
"A distracted driver ran a red light going at an extremely fast rate and hit directly into Pete’s truck," Haley said in the caption on the videos.
