Royal Marines Commando boxer Jim Cusick grabbed his international chance with both fists as he beat Irish champion and European No 7 Alho Carlisle, staking a claim for a shot at the Commonwealth Games and Olympic Games.

The Thin Destroyer started at a ferocious pace, and an explosive hook sent the Four Nations champion reeling into the ropes in the first round.

After an even second, Cusick upped the tempo to an amazing pitch in the third as his opponent started to feel the pace.

Relentless pressure in the fourth saw the Irishman covering up and holding, but it was all in vain as Cusick closed out the fight and took the laurels.

To add to the victory, Cusick was also chosen as best technical boxer on the night, and the bout was deemed the best on the card.

Navy boxing coach Q Shillingford said that in the space of three seasons Cusick had worked very hard to develop from a good club boxer to a full international.
