Sergey Spivak

Sergei 'The Polar Bear' Spivak is a heavyweight who wins the way few in the division do - with grappling. Strong wrestling, heavy top control and a real submission game make him an unusual problem in a weight class built on knockout power, and he's used that style to climb into the rankings as a young contender.

The signature win of his career is a dominant grappling victory over beloved knockout artist Derrick Lewis, the kind of result that shows exactly how he beats bigger punchers: take them down and grind them out. He's tested himself against the division's elite and settled in as a tough top-fifteen presence. Fans appreciate the technical, control-based approach in a division where it's a rarity.
