Gonzalez's rise from obscurity to 3-weight world champion and pound-for-pound status has been a relatively slow climb though that many fans expected of him from relatively early in his career. In fact you need to go back to 2008 for his first “break out” performance, a 4th round TKO win over the then WBA Minimumweight champion Yutaka Niida. It was in that bout that Gonzalez showed impressive power, skills maturity for a 21 year old fighting away from home. The following year he would return to Japan and take a clear win over Katsunari Takayama, in what was a clear decision with Takayama doing all he could to see out the final few rounds.
Since announcing himself in Japan Gonzalez has managed to make a name for himself in Mexico, with wins over the likes of Manuel Vargas, Omar Salado and Juan Francisco Estrada, all whom were beat whilst Gonzalez was the WBA Light Flyweight champion. For many fans in the west it was the Estrada bout, aired in the US, that brought Gonzalez some new fans, it was a 2012 FOTY contender and one of the best bouts in recent years between two men who essentially beat each other up for 12 highly entertaining rounds. An impressive win over Akira Yaegashi last year saw Gonzalez become the WBC Flyweight champion and further strengthen his claim of being one of the world truly elite level fighters.
This year we've seen Gonzalez finally break through to the mainstream with his HBO debut, a very impressive and destructive win over Edgar Sosa. That win saw HBO and American fight fans make it clear that they wanted more of him and just 5 months after his HBO debut he's back again in what looks to be a genuinely tough match up against Viloria.
Before we get on to Viloria we'll just talk about Gonzalez's style. He is able to box and move but at his best he's a marauding pressure fighter, he cuts off the ring, brings the fight to you and beats you with vicious and sharp combinations. If Floyd Mayweather was a defense genius then Gonzalez was his offensive contemporary with the best offensives footwork and combinations in the sport. He's fast, strong, powerful and staggeringly destructive. If has a flaw it's possibly his defense which can slip at times, though usually he's on point with that as well using a tight guard and good head movement.
Now Viloria, the American Olympian has long been a favourite of the hardcore fans and Filipino fans and for much of the last decade or so has been the one Flyweight who looked like he could become a US TV staple. Unfortunately he has often found himself have momentum stopping set backs just as he's looked ready to kick on with his career.
Saying that however Viloria is a 2-weight world champion himself and holds a really respectable number of world level wins. They include wins over the likes of Gilberto Keb Baas, Eric Ortiz, who be heat for the WBC Light Flyweight title, Jose Antonio Aguirre, Ulises Solis, Julio Cesar Mirando, Giovani Segura, Omaro Nino Romero and Hernan Marquez. Sadly losses to Romero, Edgar Sosa, Carlos Tamara and most recently Juan Francisco Estrada have stopped him from becoming the star that many hoped he would become.
At 34 years old Viloria is old for a Flyweight and has been through the hard, career draining, battles yet he is still a more than capable boxer-puncher who can really, genuinely, do every thing in the ring. He's been blessed with spiteful power, as seen in his win over Ortiz, and has developed fantastic boxing ability. The problem sometimes however is that he's not sure on whether he's a boxer or a puncher and can get stuck between the two, he's also shown questionable stamina, notable in his bouts with Tamada and Estrada. At 34 that stamina is unlikely to have improved.
Although a very good boxer Viloria is likely to be needing to rely on his power here as Gonzalez will almost certainly bring the intense pressure that has became a staple of his recent bouts. If Viloria can hurt Gonzalez then things could be interesting however we suspect Viloria will struggle to land clean and instead he will be forced to eat the combinations of Gonzalez until the challenger is eventually worn down.
Hopefully the winner of this will move towards another divisional super fight, with perhaps Amnat Ruenroeng, Juan Francisco Estrada or Kazuto Ioka. If that happens then it's going to be very hard for American boxing media and the casual fight fans to continue to ignore the Flyweight division, arguable the most exciting division in the sport today.
