14-Year-Old Jonny Mezheritskiy Wins Arte Suave 135-Lb Championship Belt

At just 14 years old, 10th Planet Oakland’s Jonny Mezheritskiy stepped into an Arte Suave superfight against the reigning 135-pound adult champion and came away with the championship belt.

Despite the significant age and experience difference, Jonny submitted the defending champion to capture the title, marking an impressive milestone in his development as a young competitor.

Jonny has developed his Jiu Jitsu at 10th Planet Oakland under head coach Michael Hillebrand, competing from a young age and continually testing himself against increasingly difficult competition.

Taking on an adult champion at only 14 years old was already a serious challenge. Winning the match by submission made the accomplishment even more special and demonstrated the level young athletes can reach through consistent training and competition experience.

The victory added another championship to 10th Planet Oakland’s growing competition record and represented a proud moment for the academy’s youth competition program.

Congratulations to Jonny and his family on an incredible achievement.
