Yuki Ishii had 14 points (13k, 1a), while American Foluke Akinradewo had 13 (7k, 3b, 3a) for the Springs. Neriman Ozsoy led all scorers with 19 (18k, 1b) for the Queenseis.

The Arrows won the battle on both sides of the net with 21 points (+13 kills (56-43) and -8 errors (5-13)) and 6 more blocks (16-10). Nanami Inoue was a wall for the Arrows with 8 blocks.
