SPOKANE, WASH. >> Hawaii’s big game hunter sprung the bear trap on California.

Quincy Smith, the Bay Area guard who grew up idolizing the Golden Bears, spent Friday sending Cal into hibernation, as he scored a career-high 19 points in the Rainbow Warriors’ galvanizing 77-66 upset in the NCAA Tournament first round at sold-out Spokane Veterans Memorial Arena.

Smith was unapologetic about helping his 13th-seeded team become one of several underdogs Friday to bust brackets across the country. UH (28-5) earned the right to face No. 5 Maryland in the round of 32 on Sunday.

“In my bracket I had us winning … so I don’t know about everybody else,” the UH co-captain said with a grin at the postgame interview podium.

It was the first win by an NCAA 13 seed since 2013. UH became the first Big West representative to reach the round of 32 since Pacific in 2005.

UH’s Bay Area backcourt of Smith and Roderick Bobbitt combined for 36 points, taking it to Cal reserves Sam Singer and Brandon Chauca, who were pressed into service with starter Tyrone Wallace out with a broken hand.

“They’re really good players,” Cal guard Jordan Mathews said. “Bobbitt hit some tough shots … Smith hit a couple off the glass in the second half that hurt us. They’re a really good, veteran backcourt.”

After a few early turnovers, Smith played with poise. He hit six of eight shots from the field, and most remarkably, seven of eight shots at the line.

That’s from someone who entered the game a 43.7 percent foul shooter.

“I’ve been working on my free throws a lot in practice,” Smith said. “I hit 25 out of 30 every time we shoot in practice. I was just going out there tonight, I knew we needed every basket, every stop. Every free throw.”

Smith, who just a few days ago could barely walk straight with a hip pointer injury, came within a missed foul shot in the game’s final moments of becoming the sixth different UH player to record a 20-point game this season.

“Everyone knew he was hurt. He’s a tough guy, a tough kid,” said Smith’s younger brother, Kendall, who plays for Big West foe Cal State Northridge but sat with his family in the Hawaii fan section Friday. “I remember 6 a.m. workouts when we were in high school, sometimes he’ll be banged up but he’ll never miss a workout, stay home, sleep or whatever.”

Smith’s fortitude was key with UH’s top offensive player, Stefan Jankovic, on the bench with four fouls for a 13-minute stretch of the second half.

UH even went to a rarely used zone to protect its remaining players from further foul difficulties.

“I couldn’t really get a feel for how they were calling it,” Smith said. “I kind of stuck to my game, I didn’t drive it all the way in too much. I tried to get a couple floaters in, a couple pull-ups. Because they had some really big guys.”

He sank two bank shots, then got a steal and drove in for a difficult, twisting layup. His hoop on a hanging drive with 4:10 to go, and two free throws with 3:09 left kept Cal at bay.

Once the buzzer sounded, Smith flapped his jersey in celebration at the several hundred UH fans directly across the court from the Rainbows’ bench.

“It’s a great experience,” he said outside the UH locker room. “I feel like we deserved it after all we’ve been through. Three coaches in three years, now we got the postseason ban next year. So this win, this means a lot. Setting records, 28 wins, the most in school history. First tournament win in school history. So it was great.”
