Nikita Tszyu Goes 13-0, Family Now Unbeaten in 54 Fights

When boxing legacy meets present-day talent, something special happens in the ring.

Nikita Tszyu improved his perfect record to 13-0 Wednesday night with a sixth-round stoppage of previously unbeaten Spanish fighter Oscar Diaz in Newcastle, Australia. The victory wasn't just personal—it extended one of boxing's most remarkable family achievements.

Combined with father Kostya's 18-0 home record and brother Tim's 23-0 mark on Australian soil, the Tszyu family now stands at an astounding 54 wins without a single loss. It's a testament to skill, dedication, and the kind of excellence that runs in the bloodline.

The 25-year-old nicknamed "The Butcher" looked career-best sharp from the opening bell. He dropped Diaz with a powerful left in round two, then continued his dominance through five rounds against a fighter they call "El Toro" (The Bull) for his toughness.

Diaz had won all 16 of his previous fights and smiled through early punishment, but even the toughest bulls eventually fall. A devastating left-right combination in round six ended the Spaniard's night and his unbeaten streak.

Why This Inspires

Nikita Tszyu is doing something incredibly difficult: forging his own path while honoring a championship legacy. His father Kostya is a Hall of Famer, and brother Tim won the WBO super-welterweight belt by knocking out Tony Harrison in 2023.

Instead of crumbling under that pressure, Nikita is thriving. He entered the fight ranked sixth with the IBF and is now expected to climb to number three in the division.

Potential matchups against American stars Keith Thurman or Tony Harrison could be next, putting Nikita one victory away from his own world title shot. He's proving that legacy doesn't have to be a burden—it can be rocket fuel.

The night also featured another famous boxing son making his mark. Rahim Mundine, son of former triple world champion Anthony Mundine, won his third professional fight with a unanimous decision over Lance McDonald, staying undefeated despite facing boos from the crowd.

These young fighters are writing their own chapters in their families' stories, one punch at a time.
