HAT-TRICK A hat-trick or hat trick in sports is the achievement of a positive feat three times or more during a game, or other achievements based on threes. The term was first used in 1858 in cricket to describe HH Stephenson's feat of taking three wickets with three consecutive deliveries. A collection was held for Stephenson, and he was presented with a hat bought with the proceeds. The term was used in print for the first time in 1878. The term was eventually adopted by many other sports including football (soccer), water polo, and team handball, but did not become popular in North America until the mid-1940s in the National Hockey League.
Qualifications As is the case in many sports, there are some informal rules regarding the use of the term "hat trick" in soccer. For example, if the match is tied after extra time and goes to a penalty-kick shootout, any goals scored do not count toward a hat trick. Thus, a hat trick in soccer can occur only during regulation time, added time and extra time. Any goals scored on penalty kicks before a shootout would count toward a hat trick.
Thomas Muller hit the 49th hat-trick in World Cup history during Germany's 4-0 victory over Portugal in Salvador. Page 10 | Sport Hat trick Hat-trick: Three goals scored by a player in a single match. The player will often be given the match ball after scoring a hat-trick.
