The 31 year old World Champion from Canberra was the only female to perform triple somersault in the medal round, scoring 96.59 points with her full-tuck-full jump.
“I competed in my first ever World Cup 10 years ago today and celebrated the occasion with a win in Yaroslavl today”, Peel said after claiming the sixth World Cup victory of her career.
“It has been one hell of a ride, and we get to do it all again tomorrow.”
Behind Peel on the podium was American Ashley Caldwell (96.23) in second and Liubov Nikitina of Russia (93.41) in third.
Peels teammate Abbey Willcox qualified for finals in eighth place but was unable to take part after crashing her last jump in finals training and injuring her knee.
In the aerial skiing World Cup standings Peel maintained the world number one yellow leader’s bib on top of the field with a perfect 200 points after two competitions. Emma Weiss of Germany sits in second place with 109 points, with Ashley Caldwell in third place with 100 points.
Peel will be back in action tomorrow competing in the second World Cup event in Yaroslavl.
