Amari Jones KO3 Vincenzo Gualtieri ... Amari Jones is now a legitimate middleweight contender thanks to a third-round knockout of Germany's Vincenzo Gualtieri on Friday in San Jose, California. Jones, originally from Oakland, California, is 17-0 and ready for a title fight in one of boxing's weaker divisions. Gualtieri (25-2-1) briefly held the IBF middleweight championship in 2023. Jones landed hard body shots in round three before and after dropping Gualtieri for the first time. Moments after Gualtieri beat the first count, he was down again. The referee saw him struggling badly and ended the fight without reaching a ten count. It was the right decision.
