MUNICH - World champion Marco Huck has defended his WBO cruiserweight title for the seventh time after a 10th-round knockout of Argentina's Hugo Hernan Garay.

In front of 3500 fans at Munich's Olympic Ice Arena on Saturday, the 26-year-old Huck knocked Garay to the canvas in the first and 10th rounds.

Garay was counted out by referee Luis Pabon after exactly one minute of the 10th round as Huck picked up the 24th knockout of his career and the 32nd victory, while this was the sixth defeat for Garay since he turned professional.

Huck had one point deducted in the third for hitting his opponent on the back of the head, but was otherwise rarely tested by the South American.

The champion can now fulfil his dream to marry on July 30 as a world champion.

Garay, 30, caused a stir before the fight by insisting he was going to "kill" Huck and stripped naked for Friday's weigh-in, something he has often done in the past.

Meanwhile in Honolulu Brian Viloria won a unanimous decision over Mexico's Julio Cesar Miranda on Saturday night to win the WBO flyweight championship.

Hawaiian Punch controlled the fight from the start, flooring Miranda in the opening minutes and landing body blow after body blow throughout the fight.

Viloria was badly bloodied but walked away with the belt.
