3 May Ivan Calderon w tdec 9 Eduardo Marquez, Mandalay Bay Resort & Casino, Las Vegas, Nevada, USA - WBO. Referee: Tony Weeks. Scorecards: 89-81, 90-80, 90-80. Having been a champion for just 36 days, Marquez (105) was soundly outboxed by Calderon (104), who buzzed around him and picked him off from distance to walk away with virtually every contested round. A very ordinary fighter, Marquez had been cut over the right eye in round three and taken a standing ‘eight’ count after being knocked into the ropes by a right-left in the sixth before the fight went to the cards at 0.43 of the ninth when the flow of blood was making it too difficult for him to see.
