By Eric Thomas: In a shocking upset, 36 year-old Nate Campbell (32-5-1, 25 KOs) had too much stamina for WBA/WBO lightweight champion Juan Diaz (33-1, 17 KOs), beating him by a decisive 12-round unanimous decision tonight at the Plaza de Toros, in Cancun, Quintana Roo, Mexico. The final judges’ scores were 116-111, 115-112 and 114-113, all for Campbell. The first card, though, seemed the most accurate of the bunch, for Campbell dominated the fight after the sixth round when Diaz faded badly after tiring out from his early fast start.
The timing of the fade for Diaz conveniently came about at the same time that Diaz was cut over his left eye, which perhaps gives him an excuse for his loss. However, Campbell appeared to just have better overall endurance than Diaz, and just plain out-hustled from the six though the twelfth as he landed both the sharper and more numerous shots during that time.
