Interesting fights ! The Shigeoka Brothers are the best in the division for me, after I have Oscar Collazo and Hasanboy. The 5 best filipinos boxer in Strawweight are also very strong and powerful.
After that I think we will have a unification match between Yudai or Ginjiro vs Oscar Collazo. I hope we will have news about Erick Rosa against the WBA Super Champion Niyomtrong "Knockout CP Freshmart". And former WBC World Champion Chayaphon Moonsri "Wanheng Menayothin" is still not officially retired yet at 38 years old. Panya Pradabsri former WBC Minimumweight Champion ranked #3 by WBC in Light Flyweight divisuon will probably fight Kenshiro Teraji for WBC Light Flyweight Championship, Kenshiro is the favorite but he is not at his prime anymore the thai have his chance. Another boxer that I love in this divisio is DianXing Zhu a chinese who have a powerful punch.
We will compare Yudai's performance with Collazo and possibly Chayaphon Moonsri. Moonsri beat him by unanimous decision and Collazo beat him in the 7th round by retirement.
He's getting older and he's getting bogged down against little-known boxers and still taking a lot of punches. I put him behind brothers Shigeoka and Collazo. But he is well ranked in the WBA he could beat Niyomtrong. Erick Rosa has just left the WBA regular title vacant and moved to Light Flyweight.
