2005-05-07 Juan Manuel Marquez w pts 12 Victor Polo, Mandalay Bay Resort & Casino, Las Vegas, Nevada, USA - IBF/WBA. Referee: Richard Steele. Scorecards: 119-108, 118-109, 120-107. As in his previous defence Marquez (125) was up against another counter-puncher, but although he won by a large margin on the cards it was anything but interesting. Despite Polo (126) being the taller of the pair whenever he threw the southpaw jab he was countered by a left hook, and through the opening six rounds Marquez edged each round before dropping his rival in the seventh with a hard right. That looked to be the signal for Marquez to move up a gear, but for the next few sessions he went back to playing the waiting game. Even though Marquez eventually upped the pace in the 11th and 12th he was ultimately content to settle for the points.
In a battle for the WBA 'second tier' title, Chris John made a successful defence when forcing Tommy Browne to retire after the ninth round at the Panthers World of Entertainment Complex, Penrith, NSW, Australia on 7 August.
John was fully recognised as the WBA champion at the end of August after Marquez forfeited the WBA ‘super’ title for rejecting a rematch against Manny Pacquiao. A week earlier, Marquez had been stripped of the IBF belt after he had failed to negotiate a match against the body’s mandatory challenger, Fahprakorb Rakkiatgym. Following that, Rakkiatgym was matched against Valdemir Pereira in a fight for the vacant title.
