From WBC:
KOSEKI DETHRONES KUROKI TO WIN 2ND WBC BELT
By Joe Koizumi
WBC female 102-pound champ Momo Koseki (23-2-1, 9 KOs), 103.75, impressively captured the WBC 105-pound belt, dethroning compatriot Yuko Kuroki (17-4-1, 8 KOs), 105, by a unanimous decision (97-93, 98-92, 96-94) over ten speedy rounds on Sunday in Fukuoka, Japan.
It was a contest of the southpaw titleholders, with Koseki showcasing her superior volume of punches that confounded the less experienced local favorite. After the seventh Koseki was leading on points of the open scoring system—68-65, 69-64, 67-66.
Kuroki upped the pace, but the more aggressive Koseki got her second wind, to take the initiative down the stretch. Koseki has retained her WBC atomweight belt on seventeen occasions! She will now have to decide which of the WBC belts she prefers to keep and defend from now on, after talking with her manager Masayuki Ariyoshi, who has cultivated Koseki into such an excellent fighting champion.
