Who wins a fight between Rigo and Santa Cruz?

I believe Santa Cruz purposely allows his opponents to survive longer than they should. Santa Cruz has said that although he has the one-punch KO power, he prefers his fighting style of methodically break down opponents, and that dishing out a beatdown over 12 rounds is much more effective than (and can cause just as much damage as) a one-punch KO.

While I do not know if Santa Cruz can take the shots Donaire did, if he is able to control the fight from the get-go (and he usually does), it's not going to matter. If Santa Cruz is allowed to get his body shots in early, it will be a long night for Rigo.
