Overweight Nery stops Yamanaka in two, Iwasa defends 122lb belt
Luis Nery wasted no time inflicting an even quicker victory on Shinsuke Yamanaka on Thursday, just 24 hours after coming in over three pounds heavy for their vacant WBC title clash.
The Mexican had initially weighed 123 pounds for the bout but came back to re-scale and was officially marked down at 121 pound for the 118 pound fight.
Yamanaka agreed to continue with the contest with an on-the-day weight stipulation set, although still found the weight difference too much.
The much-bigger Nery took Yamanaka out in the second session after dropping him four times, seven months after taking him out in the fourth session of their first meeting, with only the Japanese competitor eligible to win the WBA bantamweight belt.
After the fight, Yamanaka once again announced his retirement from the sport.
In the co-feature, Ryosuke Iwasa made the first defense of his IBF super-bantamweight title with a unanimous decision win over Ernesto Saulong.
A gulf in class was apparent as Iwasa racked up the rounds on his way to a comprehensive 120-108, 119-109 and 118-110 victory on the cards.
Other results saw former world champions meet at super lightweight as Takahiro Ao decisioned Gamaliel Diaz over eight rounds, whilst super flyweight Isao Aoyama won over six rounds against Satoshi Tanaka.
Rounding off the bill, Hiroto Murakawa scored a first round knockout over Koki Nakagawa on his debut, before welterweight Rai Jikihara defeated Taison Togashi in the second on his pro bow.
