Hatton in a great fight, his inside game frustrates Mayweather who likes to stay at range. Roughhouse fighting wears Roger out.
I see Hatton wearing Mayweather down, catching and stopping him between 8 -12 rds. Rodger Mayweather's chin would eventually betray him as usual.
Nice Contrast in styles. Roger didn't throw a lot of punches. But he had great ring generalship and an array of weapons. He should be able to control with the jab and hit Hatton on the way in. Hatton has to get under the jab and consistently get inside, where he can outwork Mayweather. I'll go with the former happening and Roger holding Hatton off for a rather close decision.
