Aroldis Chapman
Larsen's perfect game remained the only postseason game in which any team faced the minimum 27 batters until Kyle Hendricks and Aroldis Chapman of the Chicago Cubs managed to achieve the feat in Game 6 of the 2016 National League Championship Series. In that game, the Cubs gave up two hits and a walk and committed a fielding error, but managed to retire all four baserunners, three via double plays and one on a pickoff.
