In the National Hockey League (NHL), the phrase "50 goals in 50 games" (50-in-50) refers to a player scoring 50 goals within the first 50 (or fewer) games of his team's season. An extremely rare feat, the NHL has only officially deemed five players in eight different seasons to have reached the mark; Brett Hull is the most recent occurrence, having done so in 1990–91. Wayne Gretzky (three times) and Hull (twice) are the only players with multiple official 50-in-50 accomplishments.
