Nathan Chen goes into 2018 — the Olympic year — as the only undefeated male figure skater this season after notching the most prestigious victory by an American since the Sochi Olympics.
The 18-year-old U.S. champion won the Grand Prix Final, the second-biggest annual competition and the biggest pre-Olympic event this season.
The last American singles skaters to do so were Alissa Czisny in 2010 and Evan Lysacek in 2009, the latter en route to Olympic gold. In fact, four of the five men to win the Grand Prix Final in Olympic seasons went to win the Winter Games, too.
