The Rizing Fukuoka, who gutted their roster of several prominent bj-league veterans in the offseason, made another big move on Monday.

Head coach James Duncan was relieved of his duties a day after his team defeated the Saitama Broncos twice in their two-game series last weekend. His assistant, Ken Hamanaka, was promoted to head coach.

The 25-year-old Hamanaka becomes the youngest bench boss in bj-league history.
