Oleksandr Usyk stopped Marco Huck to retain his WBO cruiserweight world title and progress into the World Boxing Super Series semi-finals.
The unbeaten Ukrainian dominated from start to finish and after a period of non-stop aggression, the referee was prompted to put Huck out of his misery and wave off the contest in the 10th round.
The win in Berlin means that Usyk, 32, will next face the winner of WBC champion Mairis Briedis's quarter-final clash with Cuban Mike Perez, which will give the 8/13 Sky Bet tournament favourite the chance to unify world titles.
Briedis is 5/1 to win the tournament and Perez 16/1.
In just his 13th fight in the paid ranks, Usyk, a 2012 Olympic gold medallist, showed incredible timing and accuracy from the first bell and his power quickly forced Huck onto the back foot.

In the second round, the Ukrainian brought into play a potent southpaw jab as he expertly controlled the distance, often making Huck appear sluggish and outclassed.
The one-sided beating continued and even though Huck tried to apply some spoiling tactics, it only spurred Usyk on to throw and land even more power punches that saw the German's face reddening further.
Former cruiserweight world champion Huck showed bravery and guts to withstand Usyk's onslaught for so long, but eventually the referee decided the German fighter had seen enough in the 10th after a barrage of perfectly timed combinations were met with little reply.
