LAS VEGAS: Ireland’s Callum Walsh defeated Mexican Carlos Ocampo on points to kick off Dana White’s Zuffa Boxing on Friday.

It represented a low-profile launch of a promotion that has the potential to make a major impression on boxing in the US and its functioning.

Walsh, who fought on UFC Fight Pass and later joined Zuffa Boxing, led by UFC president White, had a mission to go out there and deliver a knockout, but failed to get in rhythm against a stubborn Ocampo.

It was a consistent game, although the Cork man was deemed to have been knocked down in the sixth round after what seemed to have been a loss of balance, but not a fall.

The 30-year-old Mexican was never apparently dented, and Walsh made several landings with his left hook, which was undoubtedly the most effective one in his arsenal, during the 10 rounds.

Reflecting on his victory, Walsh said that he only feels good when the opponent gets knocked out.

“I’m never happy with the performance unless I get a knockout,” said Walsh, whose record is now 16-0.

The three judges gave a big decision to Walsh by 98-90, 98-90, and 97-91.

However, with Walsh being 24 years old, he is still in the learning stages of his trade, and now he finds himself in the middle of a boxing promotion that is also trying to make its way in the sport.
