Guerrero UD. Not enough time spent at 147 to have built KO power but I reckon he's got the pace/stamina to dispatch of Berto in the same way he did Aydin.
Berto needs to use his size n strenghth ( steroids ) to try n bully the ghost n stop him throwing 100 + powder puff punches in a round
Im not convinced Guerrero has the size to make an impact at 147. He'll outbox Berto for 5/6 rounds before getting worn down later on in my opinion. Berto TKO in 9 or 10 rounds.
Pedrales got smacked unconscious by a wild left hand not long ago. Both Pedrales and PedRTO should be ashamed of themselves.
