Cuevas for sure. Tito's a pretty good puncher himself but Pipino broke bones. He took KOing to another level. Cuevas by KO after a valiant effort from Trinidad.
Considering Tito was a slow starter, Cuevas has a legit chance of blasting him early. But even so, jumping Tito might cause Cuevas to walk into something big. After 3-4 rounds, I think its all Tito and he KO's Cuevas in 6. If they fought 10 times, I think 6-7 times Tito stops him. 3-4 times outta 10, Cuevas blasts Tito early.
If Cuevas finds his chin early ala Yori Boy Campas it would be over for Tito, but if he fights a controlled, careful bout and dosen't leave his chin exposed then Tito's superior technique and accuracy may prove to too much for Cuevas.
