Senior McKenna Ross connected on an X play to give Hawaii the first of three match points at 14-13. UCSB held off two but not the last, with Iosia nailing her final serve.

“It was the fight, the fight at the end for us,” Hawaii coach Robyn Ah Mow said. “After we didn’t win it (when it was 15-14) I was like ‘Dang.’ Then I realized that Norene was our next server and I was like, ‘OK.’ ”

It was more than OK. It was huge.

“At that point, I just wanted to kill it,” said Iosia, who was one kill away from a triple-double. (33 assists, 16 digs, nine kills). “I just wanted to end it.”

Igiede finished with 10 kills and was in on nine of UH’s 10 blocks. Ross also had 10 kills against two of her former high school teammates, sisters Lindsey and Gigi Ruddins.

The Wahine had no answer for Lindsey Ruddins in Set 2. The conference kills leader accounted for seven of the Gauchos’ first eight points, with seven kills and ace.

Every thing went right for Ruddins, including one of her 13 kills in the set a dig-kill on her overpass of a serve by McKenna Ross. Ruddins hit .500 with just one error in tying the match 1-1.

The Gauchos trailed 11-9 in Set 3 but seemingly were energized after their coaching staff was hit with a yellow-card warning. At 14-14, the seventh and last tie, UCSB used two blocks and another kill by Ruddins to pull away for good at 18-14.

In the must-win Set 4 for Hawaii, the Wahine broke the 17-17 deadlock on a 6-0 serving run by Iosia that included her third ace of the night. Ruddins, who had 22 kills though Set 3, had just three in Set 4.
