Hawaii’s Guilherme Voss has been tested on a volleyball court more this season than any other he has played.

The 6-foot-7 senior middle blocker was rewarded with his third All-Big West Conference selection as one of two Rainbow Warriors selected to the 14-player first team released on Wednesday.

UH freshman Tread Rosenthal was one of four setters selected to the first team and earned All-Big West Freshman Team honors with Hawaii opposite Louis Sakanoko.

Voss, who is UH’s career hitting percentage leader with a .518 clip, suffered through more Big West losses in the regular season (five) than in his entire career coming into his final year as a fifth-year senior.

On the eve of the start of the Outrigger Big West Men’s Volleyball Championship at SimpliFi Arena at Stan Sheriff Center, Voss admitted it has been a grind and a real test just to get to this point as the No. 3 seed in the tournament opening with No. 6 seed UC Santa Barbara tonight at 7 p.m.

“This one more than any other has just been more about grit and battling and just really putting your effort out there rather than just straight up talent or how it would naturally come for us,” Voss said Wednesday.

It has felt like a battle on a daily basis in the gym for the Rainbow Warriors, who are trying to return to play in the NCAA Tournament for a fifth straight time.

Voss has never not made the NCAA final since he arrived to UH and first played in the COVID-19 shortened 2020 season. UH won national titles the next two years and made it to the final last season before losing to UCLA.

UH looked poised to get back there again, earning a No. 1 ranking midway through the season until Spyros Chakas’ injury changed everything.

Trying to find the positives out of a tough situation, Voss did point out it has felt like postseason volleyball in every match since, and they should be ready for this week’s win-or-go-home tournament.

“Come this time of year, a lot of teams, as (Hawaii coach) Charlie (Wade) would say, reflect on their own mortality,” Voss said. “I feel like we’ve been facing that for the entire year.”

Voss has said he has tried to provide a leading voice in practice to get the best out of his teammates heading into the final month of the season.

UH owns a road win over No. 2 seed UC Irvine and took No. 1 seed Long Beach State to five sets inside the Pyramid in Long Beach, Calif., since losing Chakas to injury.

It has also lost matches to No. 4 seed UC San Diego and No. 5 seed Cal State Northridge.

With the Anteaters and the Beach splitting their final two matches of the season against each other, with both winning in three sets, it makes for a possibly wide open BWC tournament that any team could pull out.

“It certainly wouldn’t surprise you,” Wade said Tuesday.
