New York’s slugging first baseman hadn’t hit a home run on a changeup since June—until he delivered in the exact right moment to take down the Brewers.

The origin of the purported rally gourd goes like this, according to Alonso: A week ago Thursday, when the Mets had an impromptu day off in Milwaukee after escaping rainy Atlanta, he and his wife, Haley, went to a farm in Wisconsin. He bought a pumpkin.

The New York Mets completed a heart-pounding comeback win to advance to the National League Division Series. During Game 3 of the Wild Card Round on Thursday, Mets slugger Pete Alonso blasted a go-ahead three-run home run in the ninth inning against the Milwaukee Brewers to lift his team to a 4-2 win.
