Kalaheo's Sivan Leoni thinks this year's team is his most "refined" in his five seasons as coach.

Being "refined" usually means doing things that don't show up in the box score — serve-receive, setting the right player and playing with confidence.

They are skills attained from big-match experience, and senior leadership from players like setter Chris Tumaneng and outside hitters Mana Guerreiro and Elias David.

Guerreiro had seven kills and three aces, David added six kills and Tumaneng ran a smooth offense as Kalaheo repeated as O'ahu Interscholastic Association boys volleyball champion last night, beating Radford, 25-14, 25-18, at McKinley.

Kalaheo, the East's No. 1 seed, will have a bye in the Division I state tournament, Nov. 7 to 10 at McKinley and Stan Sheriff Center. Radford, the West's top seed, also will participate in the state tournament.

"The states is the bigger goal," Leoni said. "The OIA is just a step to get there."

David took over game 1 by serving five in a row to put Kalaheo (14-1) up 13-7. The run included three back-row kills by David, an ace and a tough serve that led to a kill by Chase Moses.

Radford (14-1) had three hitting errors and three service errors the rest of the way.

"I think they had the advantage because they've been here more than us," Radford coach Damon Reyes said. "This is our first year we've ever been here so the boys were just feeling it out.

"There is nothing I can do for that except hopefully in the next five years we can keep coming back and coming back."

In game 2, Kalaheo went up 16-10 on a kill by Guerreiro, but Glen Klaiber served five straight to get the Rams within one.

"We knew we had to stay calm and try to get side outs and take it point by point," Tumaneng said.

With the score 21-18, Tumaneng served the final four points. His ace set up match point, and a block ended it.

"We wanted to win this so bad, this was our goal from Day 1," Guerreiro said.

Tumaneng and David are both four-year starters, and Guerreiro has started since his sophomore year.

"Mana, me, Elias, we played since freshmen — big games — so (experience) played a big role," Tumaneng said.

The Mustangs also got contributions from middle blockers Caswell and Moses, who had five kills apiece.

"Once you start jumping on our middles, we're going to set the outside," Leoni said.

A perfect example was early in the second game when a couple of Radford blockers collapsed on Caswell and Tumaneng set Cliffton Pires, who put down a kill without a blocker up from the right side.

Kalaheo had six aces and repeatedly made Radford scramble to get into its offense.

"When we can push them away from good passes, they're going to stay away from their middles," Leoni said.

The Mustangs also used deft ball control to rack up 26 kills and just eight hitting errors.
