Josh Harrellson's 32-point, 10-rebound effort steered the Osaka Evessa to an 80-62 victory over the winless San-en NeoPhoenix on Saturday.
Harrellson, a former University of Kentucky and NBA big man, made 13 of 18 shots from the field in the series opener in Toyohashi, Aichi Prefecture.
The Evessa (6-4) led 37-29 at halftime, then outscored the hosts 24-13 in the third quarter to build a big cushion.
