Martinez will win again, but Williams' Goosen's judges will not allow such. This is a set up! Williams refused to fight unless he got all his judges, his personal referee, his catch weight, his commentators, full control by his promoter Goosen and his venue.
Martinez should have the ability to win clearly via decision. It remains to be seen if he has the genuine steadiness and composure to make a proper fool out of Williams. Sergio did indicate in a recent interview he might have let some of that go in the first fight. For me that's encouraging. I expect a Martinez victory.
Williams by KO. He came back strong against Quintana, and I expect him to come back strong here, too. Now, I'm not predicting a second round KO or anything, but if Williams hurts Martinez, or stuns him, look for the Punisher to jump right on top of him and start throwing down.
