Anthony Mundine holds out plucky Kiwi Anthony Mundine has held out plucky Kiwi Gunnar Jackson in their WBA light middleweight fight in Brisbane. Anthony Mundine takes on Gunnar Jackson at Brisbane Entertainment Centre. IT would hardly have made Floyd Mayweather sit up and take notice. But Anthony Mundine still hoped he had taken the first step towards challenging the world's best pound-for-pound fighter with a unanimous points decision over Kiwi Gunnar Jackson in their WBA light middleweight bout in Brisbane last night. Mundine could have been forgiven for simply being happy that Jackson had turned up after a chaotic lead-up to what the former NRL star dubbed a "fill-in fight." However, Mundine at times may have regretted that he had as the plucky Kiwi went down swinging in the 10 round bout. Mundine (46 wins, 27 KOs, five losses) hopes the fight will lead to a match-up with the renowned Joshua Clottey, who has gone the distance with Manny Pacquiao and Miguel Cotto. I regained my killer instinct. I had bad intentions when I hit him. I wanted to hurt him," Mundine said. In the (Daniel) Geale fight last year I wasn't right mentally. But Gunnar made me switch on straight away because I knew this guy meant business. I put pressure on him at a world class pace. All I need to do is switch on mentally. Mind over matter, that is how it happens. At 38, Mundine hopes remaining active in 2014 and racking up wins over the likes of Clottey will force Mayweather's hand by year's end. Still, staring down Mayweather appeared a world away after he held out Jackson, a 27-year-old drain layer who agreed to fight barely a week ago. Initial opponent Carson Jones last week pulled out due to the 'flu and his replacement - American journeyman Billy Lyell - failed to sign his contract on time. That forced Mundine to ask Jackson (18 wins, six knockouts, five losses, three draws) if he was doing anything this week and wanted to visit Queensland for the first time. "Gunnar the Stunner" - named by his parents after 80s thoroughbred "Go Gunnar" - had not trained in four weeks and had just days to prepare for the biggest fight of his unheralded career. His trainer Chris Walker said ideally Jackson would have needed a six week lead-up but had kept his fingers crossed for a boilover after his charge had "remained reasonably active over December." Still, Jackson ensured a solid workout for Mundine. Mundine eventually outpointed his rival 100-90, 100-90, 100-90. Mundine had rated Jackson "more dangerous than Mosley" ahead of the bout due to the Kiwi's desperation to register a huge notch on his belt. And Mundine was proved right as the Kiwi ensured the former NRL star was on the back foot from the outset. Mundine met Jackson's ferocity but was never able to put the plucky Kiwi away.
