Official Weights: Cotto 153.5, Canelo 155

Lineal middleweight champion Miguel Cotto (40-4, 33 KOs) surprisingly weighed in even below the junior middleweight limit. He only weighed 153.5 lbs., which is .5 lbs. under the junior middleweight limit during their official weigh-in at the Mandalay Bay Resort and Casino, North Convention Center - Islander Ballroom on Friday afternoon.

Mexican star Saul Canelo Alvarez (45-1-1, 32 KOs) tipped the scales spot on the contracted catchweight limit at 155 lbs.

Canelo has a clear advantage in size for this match-up. The catchweight at 155, I think will play to his advantage in my opinion, because Canelo seemed to struggle to make 154 lately. He tends to tire in the late rounds of his previous fights at 154. An indication he might outgrow his division. One pound could really make the difference here. At 155, it made him not that much drained during the training but not too heavy to make him sluggish and slow. But he should not over re-hydrate.
