McDavid first played in an IIHF tournament in 2013 when he joined the Canadian under-18 team at the 2013 IIHF World U18 Championships in Sochi, Russia. The youngest player on the Canadian team, McDavid played his first game against Slovakia on April 18, where he recorded one goal and two assists. After recording a hat trick against Sweden, McDavid was named the best Canadian player of the game. He led the tournament in goals and points while helping Canada win a gold medal for only the third time since the tournament's inception in 1999, defeating the four-time defending champion, the United States, in the final. Jim Nill, then chief scout for the Detroit Red Wings, said of his performance that, "I guess you could say he is kind of The Next One. Every so many years [a player arrives like] Gretzky, Lemieux. I think he is making a statement. Is he [the next Sidney] Crosby? I think he is the next guy."
