I vaguely remembered hearing about Rodriguez before the fight was made, probably due to him having KO'd GKB earlier this year, but I hadn't seen any of his fights. Even from glancing at his BoxRec you can tell he's more than likely a better fighter than his pretty unflattering numbers suggest. The only fight of his I've seen since is the only one I could find, which is his draw against Pedro Guevara(the dude who dropped a split decision against Casimero not long ago).
Despite him being better than I anticipated I can't say I'm any less shocked by the upset he pulled on Saturday though. I mean, he's decent but appears fairly basic. Consistent pressure fighter, very much left-hand orientated, dodgy hair, and relatively solid defensively(seems like he can take a shot too). I'm guessing Joyi was winning comfortably before getting nailed by a left hook or something, I'd really be surprised if he wasn't winning the fight anyways. Then again I might be selling the dude short, he's only in his early 20's and his recent string of results suggest that he's ever-improving. In a stylistic sense he just seems too straight-forward and basic to really take rounds off Mabere consistently though, Joyi's a big straw and I would've thought he even could have played into Rodriguez's hands by fighting toe-to-toe and still won. Obviously not.
I'm damn disappointed with Joyi really, I rated the dude as much as I was frustrated by him.
