Only one shorthanded hat trick has ever been scored in NHL history—Theo Fleury achieved this singular feat on March 9, 1991, in a 8-4 Calgary win over the St. Louis Blues. The achievement is improbable at the college level—it has happened only six times in NCAA Division I history, according to the Hockey Hall of Fame—though it is probably not so rare at the rec-league level. But one place it had never happened before was the United States Hockey League, the top junior level in the United States.
At least, until April 24, 2012. That's when Blackhawks prospect Alex Broadhurst (drafted 199th overall in 2011) made history by tallying this shorthanded trio for the Green Bay Gamblers against the Youngstown Phantoms in a 6-3 victory in the first round of the USHL playoffs:
Broadhurst's hat trick was not only the first of its kind in the USHL in both regular-season and postseason play, but also set a league record for most shorthanded goals in the playoffs (the previous mark was two, held by multiple players).
Broadhurst, 19, ranked third in the USHL this season with his team-leading 73 points (26G, 47A) in 53 games and sixth with a +32 plus/minus rating. Green Bay clinched their best-of-five series against Youngstown Wednesday night and will move on to the second round of the playoffs.
