The Akita Northern Happinets edged the Takamatsu Five Arrows on Sunday, winning 77-75 to record a two-game series sweep on the road.

The Northern Happinets (28-4) extended their winning streak to 11 games. They sit atop the Eastern Conference standings, fueled by a high-powered offense. But personnel changes may be on the horizon for Akita, The Japan Times has learned.

A team insider told this newspaper that the team's current roster may undergo changes this week, as early as Tuesday.
