WBO welterweight champion Manny Pacquiao has declared himself ready to face Juan Manuel Marquez for a third time ahead of their dust-up. The pound-for-pound king, who was pushed all the way by the Mexican veteran in their previous two thrilling clashes, believes his increase in power will prove decisive on Saturday night at the MGM Grand in Las Vegas. Marquez clambered off the canvas after being floored three times in the first round to salvage a draw in 2004, and then lost their rematch four years later by a single point.

The weigh-in will be streamed live on BoxingScene.com, starting at 5:30EST/2:30PST.
