Oleksandr Usyk defended his WBO cruiserweight title with a 10th round stoppage win over Marco Huck in the opening World Boxing Super Series bout.
The Ukraine fighter looked stronger and better conditioned throughout and a relentless flurry of punches saw Huck stopped on his feet in the 10th round.
The win in Berlin takes undefeated Usyk through to the semi-finals of the first World Boxing Super Series tournament.
The event will conclude in May and features a $50m prize fund. [H/T BBC Sport]
