I really think at 140 Hatton is nearl unbeatable. Pacquiao is a freak, and a great fighter no doubt, but IMO, he lost both times to Juan Manuel Marquez. I also think the fight against DeLaHoya really only once again proves the adage that when a fighter talks about retiring, he already, in effect has.
I think Hatton wears him down in a classic brawl and finishes him in the later rounds.
Hatton, TKO9
