It's not THE Arthur Mercante BTW. It's Arthur "The ref gene skipped me" Mercante Jr. Diaz wobbled by Addy at the beginning of the round. Diaz is REALLY REALLY wide open, I could probably counter him he's that open.
Diaz has certainly turned it on now. His hand speed is alarming and when he lets them go, He finds Addy with ease. That said he's still very wide open and alarmingly off balance with every punch. Mixed bag so far on Diaz.
