The New York Mets are headed to the National League Division Series for the first time in nearly a decade thanks to a dramatic go-ahead home run from Pete Alonso against the Milwaukee Brewers.

Seven minutes after the Mets advanced, and as the team celebrated on the field, the sections of fans behind New York’s dugout at American Family Field began loudly chanting, “Pete A-lon-so! Pete A-lon-so! ” It would be the first of more chants for Pete Alonso.

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.
