Yay, I finally predicted a fight
It seemed like a forgone conclusion since they match up well, and Jay was available.
Hieron has been a little chinny in the past, but I think he's drastically improved over the last couple years. His last bout against Jason High was really impressive--he blew him right out of the water with some improved boxing.
It's a tough test for Diaz. Hieron has pretty good footwork, and I doubt he'll allow Diaz to put together 5 or 6 punch combinations like he has against previous opponents. They both have great conditioning, so I expect either a decision, or a late round finish.
