New York Mets star Pete Alonso's three-run, ninth-inning blast off Milwaukee Brewers closer Devin Williams on Thursday night ended a slump for the free agent-to-be while helping send his team to the National League Division Series, where they'll meet the Philadelphia Phillies.

With his team down 2-0, Alonso hit a 3-1 changeup out to right, stunning the home crowd at American Family Field as the Mets won a wild first-round series, two games to one over the Brewers.
