Mitsuki Ono & Joonsik Lee Win 2017 Burton U·S·Open Junior Jam

The legendary Junior Jam went off at the 35th Annual Burton USOpen Snowboarding Championships. The field featured 25 of the top boys and girls halfpipe riders ages 14 and under competing in Vail’s 22-foot pipe in a best run format. Snowfall was steady and stoke was high as these grom riders went all out in an event that has been marked by past winners who have gone on to become household names. First place went to two extremely consistent riders—12-year-old girls winner Mitsuki Ono of Japan and 14-year-old boys winner Joonsik Lee of Korea. The challenging snow conditions and low visibility were clearly no issue as these two top riders dominated from the start with both posting the only scores in the 90s. With this win, Lee and Ono earned the opportunity to compete against the pros in Thursday’s halfpipe semi-finals.

Ono dominated the girl’s field, holding the top spot through all three runs and winning with a 93.49, the highest posted score of the day. Consistently large and clean back-to-back 540s and a Cab 7 were the moves that set her apart. Ono hopes to one day compete for her country in the Winter Olympics and looks up to 2016 Burton USOpen Champion Chloe Kim, who she’ll now be competing against in semi-finals. 2016 U.S. Open Junior Jam winner Tessa Maud of California took second place, followed by Switzerland’s Berenice Wicki in third.

On the boy’s side, Joonsik Lee has been dominating local contests around his home resort of Breckenridge, Colorado this winter. His consistency showed today as he rode large and clean with a full bag of tricks including a frontside 900, backside 540, frontside 720, a Haakon Flip and a Crippler. Eleven-year-old Valentino Guseli of Australia bumped up his 2016 Junior Jam fifth place finish to take second this year. Rounding out the boy’s podium in third was Kohlman Lecroy out of Big Bear, California.


One of the many reasons Joonsik Lee ended up on the top of the boy's podium. 

Also up for grabs was the CLIF Bar “Raise the Bar” award for best trick with Mitsuki Ono landing it for the girls with her Cab 720 and Joonsik Lee taking it home for the boys with his 900 melon grab.
