Umi Ishikawa KO3 Sothita Sitthichai... On Friday at the Singmanassak Muaythai School in Pathum Thani, Thailand, Japan's Umi Ishikawa (12-3, 10 KOs) won the WBC interim minimumweight title by knocking out Thailand's Sothita Sitthichai (10-3 kos) in the second round. This was a rematch, as the women had already met last August, with Ishikawa winning in the third round. The second time around, only two rounds were enough for Ishikawa to demonstrate her superiority by knocking out the Thai fighter in a forceful manner. Ishikawa, who showed her quality and strength once again, hopes to soon gain a fight with the true world champion of the division, Seniesa Estrada.
