Benoit Pouliot scored twice in regulation for the Rangers, who bounced back from a home loss to Edmonton the night before and won for the fifth time in six games.
The Penguins had won all four of their previous shootouts this season and 14 of their past 15 overall.
Zuccarello, the second New York shooter in the tiebreaker, tucked a backhand under the pads of Marc-Andre Fleury — who had not allowed a shootout goal all season. Evgeni Malkin beat Henrik Lundqvist to extend the game before Richards flipped a shot past Fleury to end it.
He's a special guy. Obviously we are lucky to have him. Just his talent, I'm not surprised anymore. You get to see this guy every practice, and you know what he's able to do. Obviously, it's pretty special for a guy that young to score a hat trick in playoffs, this type of a game too. Really happy for him.
