Anthony Joshua watched on with pride from ringside as Viddal Riley outclassed Mateusz Masternak to scoop the European cruiserweight title.Riley, who is managed by Anthony Joshua‘s 258 Management, was a step ahead of Masternak in every department.GettyRiley dominated Masternak to snatch the European title away from the durable Pole[/caption]The old Polish warhorse looked every one of his 38 years as he was methodically picked apart by the lightning-fast Brit.Besides a spirited effort down the homestretch from the durable Pole, Riley won every round and was handed a unanimous decision via scorecards of 118-110, 118-110, 119-109.In victory, Riley improves to 14-0 and takes one step closer to a world title.After the bout was announced, the IBF made the contest an eliminator for their now-vacant cruiserweight title.Former champion Jai Opetaia was stripped of the red and gold strap in March after competing in an unsanctioned fight with Brandon Glanton at Zuffa Boxing 4. While Glanton was ranked inside the IBF’s top 15 at 200lbs and would have therefore passed as a legitimate optional defence with the governing body’s blessing, the issue lay with the Zuffa belt.The IBF initially approved the fight on the promise that the Zuffa strap would be presented as “a trophy or token of recognition.”However, the sanctioning was withdrawn after the Zuffa belt was introduced as a “cruiserweight world title” at the pre-fight press conference.Heading into fight night, Riley was ranked No.7 at 200lbs by the IBF and Masternak was placed No.4. Riley will be boosted into one of the vacant No.1 or No.2 spots and is expected to be ordered to face fellow Brit Chris Billam-Smith, who is ranked No.3 right now. Joshua watched on with pride as Riley dismantled MasternakRiley welcomed a fight with CBS as he spoke about his next steps in the immediate aftermath.“It feels good, man, European champion, it sounds good,” said Riley.“Talk to us nice. This says I’m world-class. “The only people who beat Masternak are world-class.“You know how it goes. British, sometimes Commonwealth, then European, and you go to the next level. “We’ll sit down with the team, I feel great, and I’m ready for the next challenge.”Riley won his fight on the undercard of Derek Chisora vs Deontay Wilder at the 02 Arena in London on Saturday night.
