i got gamboa in this caballerro to me still hasnt fought no one he beat molitar and de leon who is not on the level as gamboa and gamboa compitition level is crazy he hasnt fought a mega star yet but for 14 fights they have all been good records. at the end it will be the illusiveness speed and power of gamboa who will win
But how will Gamboa deal with the awkward power-punching five inches taller and god knows how many inches more reach on him Caballero??? Personally I think Gamboa, behind on the cards, stops Celestino late, but this is a genuine 50-50 fight and would provide fireworks guaranteed. Would rather see Gamboa face Chris John, but maybe the winner of Gamboa-Caballero would deserve a shot at the 'full' WBA title. Gamboa getting a win over Caballero would be a huge coup for him, and prepare him for the tall yet less powerful Chris John really well. Chris John would have to the favourite, but Gamboa is impressive and has big power as well as fast hands that could win him rounds. John vs. Gamboa is also a very intriguing fight, yet it seems Gamboa vs. Anyone Good is intriguing and pretty much guarantees fireworks.
I would go for Gamboa here. I have not seen alot of Caballero I saw his beatdown of Molitor, his mismatch against Mejia his win over Pastrana. He is good but to be honest Molitor was not aggressive in his fight, no way would Gamboa be dominated like that. I know there is a huge size difference but Gamboa has easily dealt with fighters taller than himself before (Al Seeger 5'8" & Rojas 5'9") and Caballero does tend to lean forward as alot of taller fighters do. I would go with Gamboa here possibly by KO or on pts by 4 rd margin.
