I haven't seen much of Hiraoka but his win over geriatric Barroso didn't impress me; I think Velenzuela beats him handily.
I've not seen much of either, both of them are coming off their best wins. I was impressed by Hiraoka the other day. I never rated Pitbull so I thought him getting outboxed like that was just a matter of time. Still Valenzuela might be a bit too awkward for Hiraoka, could see him winning on points but I'd like to be surprised.
