tough fight for Pernell. but I think he wins this one by UD. He would pick it up and use his speed to control the later rounds.
Whitaker didn't have a plethora of speed at 154, not in the shape he turned up in for Vasquez, anyway. I'd favor Kalule in this one.
I think Whitaker would have enough to edge this. Was Kalule right handed and fought out of a southpaw stance?
