The reason that some elite fighters don't need numerous professional fights before stepping up in class is usually because they have a lot of experience in something similar to professional boxing. In Muangsurin's case if was Muay Thai whilst in Lomachenko's case it was his amateur amateur boxing career.
With that in mind you need to realise that Yoshikawa Nana (2-0), pictured, is no typical 2-0 fighter. She is, instead, a very accomplished amateur stand out who knows that time is against her and that she can't waste time with "developmental fights" to improve her skills. Instead she has had to fight in "live" fights early in her career and hope that she can rely on her amateur schooling to help her through the problematic patches of a fight.
Nana's record of 2-0 as a pro needs to be considered alongside her amateur record, which is a reported to have consisted of 77 fights including 55 victories and appearances at two world amateur championships. Nana may be a professional novice but she's a boxing veteran. Sadly though her amateur experience has come at a cost and she is now 35 years old with no more time to spend developing her skills. She has had 2 bouts and must now get on the fast track to success, or failure.
For Nana her next bout is a sink or swim contest as she moves up from fighting novices to fighting for the OPBF Light Flyweight title, albeit a title vacated by Naoko Shibata.
Nana, the OPBF #2, goes from fighting opponents no wins between them to taking on former world title challenger Krikanok Islandmuaythai (4-3-1, 2) who is, herself, ranked #3 by the OPBF.
Krikanok may not be that well known but she has mixed in great company, much better than that of Nana. After starting her career 4-0-1 she was unfortunate enough to be sent in to a match up she simply wasn't ready for against WBC Atomweight champion Momo Koseki. Koseki showed the gulf in skills and experience between herself and Krikanok by stopping the Thai in just 5 rounds. Since then Krikanok has lost back to back fights to Masae Akitaya and Kanittha Kokietgym. Admittedly though both of those women are world class, unfortunately though Krikanok that is 3 straight losses on her record.
Although more experienced than Nana with 8 bouts under her belt and the experience of a world title fight already under her belt Kirkanok won't be seen as the favourite. Instead it will be Nana, with her amateur background will be expected to win, a view we share with many out there.
Although Nana has a lack of world class power she does have very advanced skills for such a novice and it's those skills that we imagine will take her to the OPBF title. Hopefully, if she wins, she will continue with aggressive match ups and will manage to move on to a world title fight in the next year or two before she is physically on the slide. She has the skills to be a top fighter but father time is certainly against her.
