Many hockey players use a slapshot—a short, quick, powerful swing with the stick—to try and score a goal. The speed of this shot makes it very difficult for a goalie to react and make a save. The fastest slapshot recorded was 108.8 mph in 2012 by Zdeno Chara.20 A National Hockey League (NHL) scout believes that defensemen have faster slapshots than forwards.
