By Dan Ambrose: Dan Rafael is reporting that a deal is done between WBA World super bantamweight champion Guillermo Rigondeaux and 31-year-old former WBA Super Bantamweight Champion Poonsawat Kratingdaenggym (48-2, 33 KO’s) for December 15th on the undercard of the HBO televised fight between WBO super bantamweight champion Nonito Donaire and Jorge Arce at the Toyota Center, in Houston, Texas, USA.

The Rigondeaux-Poosawat fight was the one that Top Rank, the promoters for the 32-year-old Rigondeaux, had wanted to make. Then recently Filipino Drian Francisco had been mentioned as possibly fighting Rigondeaux, but now it’s back to Poonsawat. This is a much better fight because Poonsawat is a pretty talented fighter and is ranked #3 by the World Boxing Association at 122.

With the way that Rigondeaux was getting stunned left and right in his last bout against 22-year-old fringe contender Robert Marroquin last September, we could see a minor upset on December 15th with Poonsawat stopping Rigondeaux if he’s able to apply pressure and land his power shots.

Poonsawat, 5’4 1/2″, isn’t nearly as big as the hulking 5’8″ Marroquin, who looked more like a light welterweight than a super bantamweight after rehydrating to fight Rigondeaux. Generally, the 5’5′ Rigondeaux does well against guys his own size or smaller, and he’ll not have to worry about fighting a guy that looks to be two divisions bigger than him in facing Poonsawat.

Rigondeaux wants to get a fight against Donaire but Bob Arum of Top Rank is letting the fight marinate much in the same way he did with the Juan Manuel Lopez vs. Yuriorkis Gamboa fight. That bout never happened because Arum waited too long and Lopez got stopped a couple of times. It’s unclear if Arum is letting a Donaire vs. Rigondeaux fight marinate or if he plans on never putting them together in order to protect his bigger money fighter Donaire from taking a loss.

Putting Donaire with Rigondeaux would be a very risky thing for Arum to do because either way something bad is going to happen in that fight. Either Rigondeaux gets destroyed and loses whatever value he has to Arum or Donaire gets badly exposed and Arum sees his money value plummet.
