Auston Matthews has joined a very exclusive club.

With his goal in the first period of the Toronto Maple Leafs’ game with the Montreal Canadiens on Saturday, Matthews recorded 50 goals in a 50-game span. He also scored again in the first, giving him 51 goals over this stretch.

Only eight players had accomplished the 50-in-50 feat in NHL history. Matthews is the ninth.

Maurice Richard, Mike Bossy, Wayne Gretzky, Mario Lemieux, and Brett Hull are the official 50-in-50 scorers. Jari Kurri, Alexander Mogilny, Cam Neely, and now Matthews are known as unofficial 50-in-50 seasons, as the NHL requires a player to have scored his 50th goal in or prior to his team’s 50th game.
