TOKYO – Filipino Malcolm Tunacao lost in his bid to win a second world title following a 12th round stoppage at the hands of reigning World Boxing Council (WBC) bantamweight champion Shinsuke Yamanaka of Japan at the Kokugikan Arena in Tokyo.
Referee Michael Griffin stopped the bout after the 35-year-old Tunacao went down for the third time. The former WBC flyweight champion was twice knocked down earlier in the third.
The end came at the 1:57 mark of the 12th.
The loss by Tunacao came barely two days after Brian Viloria yielded his World Boxing Organization and World Boxing Association flyweight titles with a 12-round split decision against Juan Francisco Estrada of Mexico in Macao.
Tunacao, a native of Mandaue City but now based in Kobe, Japan, saw his five-year, 11-fight winning streak come to an end Monday night. His record now stands at 32-4-3, with 20KOs.
Yamanaka, 30, remained undefeated with a record of 18-0 with 13 KOs. It was his third successful defense of the title he won behind an 11th technical knockout of Christian Esquivel in 2011.
He retained the crown the following year by scoring a unanimous decision over Vic Darchinyan and then followed it up with a seventh round knockout of Tomas Rojas.
