With his potential next opponent in attendance -- Kell Brook -- former world champion Amir Khan showcased the good, bad and ugly of his game. The good: He scored knockdowns in rounds two and three, unleashed blistering combinations that nearly took Vargas out in the fifth and moved well from first bell to last en route to a wide decision victory.
The bad: Khan was saved by the bell twice; first after Samuel Vargas floored him with a right to the jaw in the final seconds of round two, then after Vargas staggered him with a side-winding right near the end of the 10th.
Also: Khan's stamina waned in the second half. In rounds 1-6 Khan averaged 53.8 punches per round and led 120-66 overall, 37-10 jabs and 83-56 power but in rounds 7-12 he decelerated to 43 per round while Vargas accelerated from 41.7 to 47.5 punches per round.
The connect margins also were smaller: Khan led just 79-76 overall thanks to his 31-10 lead in jabs, but Vargas prevailed 66-49 in power connects. Khan's first-half effort led to connect leads of 199-142 overall, 68-20 jabs and 131-122 power but the accuracy gaps were smaller (34%-27% overall, 25%-11% jabs, 43%-35% power). Good, but not great. Scoring: 119-109, 119-108, 118-110 K.
