Wayne Gretzky [SEP] Introduction
Gretzky became known for setting up behind his opponent's net, an area that was nicknamed "Gretzky's office". Gretzky was the top scorer in the 1978 World Junior Ice Hockey Championships. In June 1978, he signed with the Indianapolis Racers of the World Hockey Association (WHA), where he briefly played before being traded to the Edmonton Oilers. When the WHA folded, the Oilers joined the NHL, where he established many scoring records and led his team to four Stanley Cup championships. Gretzky's trade to the Los Angeles Kings on August 9, 1988, had an immediate impact on the team's performance, eventually leading them to the 1993 Stanley Cup Finals, and he is credited with popularizing hockey in California.
