WBO atomweight champion Nao Ikeyama rewrote her own record as the oldest fighter in Japan to successfully defend a title with a unanimous decision over challenger Norj Guro of the Philippines on Saturday.

Ikeyama, who is 45 years, 5 months, won her second title defense after outpunching Guro, who is 21 years her junior.

"I came close to getting a knockout but I didn't get one, so I regret that part. My punches weren't effective," said Ikeyama, who improved to 8-2 with one knockout. "My only goal is to keep winning bout after bout. I really want to make my next fight a good one."

WBO minimum flyweight Kumiko Seeser Ikehara claimed her first title defense but not in the way she would have liked: her bout against Filipina Jesebelle Pagaduan was ruled a draw after the 30-year-old Ikehara's forehead was split open from an accidental head-butt at the end of the first round.

The referee determined that it was impossible for her to continue due to the amount of blood.
