Cotto by decision. I think Cotto's jab will help him win this fight. That being said...i think Cotto's defense and chin (i'm not a sold on either) will give Margarito a real good chance. I just have seen Cotto rocked and dazed on too many occasions. Much props to him for always coming back...but eventually (unless he really tightens up his defense)...he will get KOed if he is not careful.
