Wescott, who won the Olympic title at Turin 2006 before retaining it at Vancouver 2010, won the second World Cup of the season after a photo finish with Australian Alex Pullin.
That marked former world champion from 2005 Wescott’s first World Cup victory since Arosa in March 2011 and came almost four years after his maiden win at the same venue.
At 36 years and five months, the American became the second oldest winner of a World Cup snowboardcross race behind Austrian Olympic bronze medallist from 2006 Siegfried Grabner.
And making Wescott’s performance in Telluride all the more impressive is that he was 35th at the World Cup opener in Montafon at the start of the month while he was 40th in his last race before that.
Meanwhile Canadian Christopher Robanske took third ahead of Norwegian Stian Sivertzen and eighth for Omar Visintin, who won the World Cup opener, was enough for him to maintain his overall lead.
Visintin has 1320points to his name while Pullin sits narrowly behind in second with 1300 with Markus Schairer, sixth in Telluride, third with 1200 and then Wescott fourth with 1020.
Meanwhile in the women’s race Winter X Games champion Dominique Maltais made it two World Cup wins from two in Telluride for the ninth victory of her career.
Reigning snowboardcross World Cup champion Maltais led home a Canadian one-two with Maelle Ricker taking second place ahead of Bulgaria’s Alexandra Jekova while Switzerland’s Simona Meiler was fourth.
Maltais extended her lead in the overall rankings to 1000points courtesy of the win while Ricker, the runner-up in last year’s World Cup and 13th at the season opener in Montafon, is now second.
