The bout is a mismatch due to the limitations, and recent activity, of the challenger. Argumedo hasn't fought in over a year, and he's actually just 1-1 in the last 24 months with the win coming against the very poor Irving Requena. His most notable bouts have all been defeats, with 2 decision losses to Oswaldo Novoa and a loss last year to Carlos Velarde, and although he was very competitive in those defeats there is little to suggest he should be in a world title bout.
Whilst Argumedo does lack a world level win he does interesting hold some victories over gatekeepers. In 2013 he beat both Martin Tecuapetla and Javier Martinez Resendiz, though of course those wins were more than 2 years ago and neither Tecuapetla or Resendiz have shown themselves to be world class themselves.
Despite the issues with Argumedo getting this fight we do suspect that he will give his all, he will come to fight and he will be happy to go to war with Takayama. He may not be world class be he will almost certainly give us action, especially given his toughness.
Whilst Argumedo has yet to impress it's hard not to be impressed by the champion who is one of the most exciting fighters on the planet. Takayama is a true warrior, his bouts have been among the most exciting in recent years and his brawl with Francisco Rodriguez Jr was, rightfully, regarded as one of the best fights of 2014. Technically he is flawed but those flaws are somewhat compensated for with his insane work rate, incredible toughness and his amazing will to win.
The 32 year old champion can, at times, be accused of being inconsistent and has been through a very hard career. Bouts against the likes of Rodriguez, Roman Gonzalez, Yutaka Niida and Nkosinathi Joyi have all taken their toll on his body. Despite the inconsistencies and damaging wars Takayama is still a fighter who knows how to pull wins out of the of the bag, as shown last year against Shin Ono and he knows how to turn it on when needed with huge assaults that over-whelm lesser opponents.
For us this bout has just one winner, Takayama. Almost certainly by decision with the aggressive Japanese fighter simply out working and out fighting the Mexican visitor.
