Takashi Uchiyama remains undefeated following a third round stoppage win over Oliver Flores in Tokyo, Japan.
The 36 year-old WBA ‘super’ title holder at 130 pounds made an eleventh successful defense of his belt to move to 24-0-1 and cement his place in the WBN P4P Top 50.
In the co-feature at the famous Ota-City General Gym, Ryoichi Taguchi kept a firm grip on his WBA light flyweight version after retiring Luis de la Rosa at the end of nine rounds.
Taguchi, 29, was actually behind on two of the judges scorecards as the competitive bout was called off but in the end ran out a worthy winner for coming on strong in the second half of the fight and opening up a cut on De la Rosa’s left eye.
In Osaka, Kazuto Ioka defended his WBA flyweight title by stopping former world champion Juan Carlos Reveco in eleven rounds, whilst Jose Argumendo picked up the IBF minimumweight title via a ninth round technical split decision over the seasoned Katsunari Takayama. Argumendo, 27, claimed a first career world crown in the process after being awarded the fight by two officials 87-84.
The contest was stopped early due to a cut suffered by the now ex-champion.
Also on the bill, bantamweight Takahiro Yamamoto and super flyweight Sho Ishida both scored early stoppages.
Finally over in Nagoya, Kosei Tanaka picked himself up off the canvas in the fifth session to retain the WBO minimumweight title in the very next round against Filipino challenger Vic Saludar.
In chief support, namesake Yushi Tanaka blasted out Zun Rindam in one round at super bantamweight, whilst divisional rival Genesis Servania improved to 27-0 with an eight-round points win over journeyman Hendrik Barongsay.
