Hawaii did John Wooden proud on the opening day of the late college basketball legend’s namesake tournament.

The Rainbow Warriors passed the ball like a Thanksgiving biscuit in surprising Utah 90-79 in the Wooden Legacy quarterfinals on Thursday at Titan Gym in Fullerton, Calif.

Fundamentals and form were turkey and gravy for the ’Bows. They shot 52.8 percent from the field, had 19 assists to eight turnovers, and were terrific at the free-throw line, converting 25 of 28 (89.3 percent) of their attempts.

UH (4-1) beat its first Pac-12 opponent since topping California in the 2016 NCAA Tournament first round. It had lost to Utah (2-2) the past two years in Honolulu and Salt Lake City.

“The feeling after the game was amazing, knocking off a school like that, a Pac-12 school,” said senior point guard Brocke Stepteau, who poured in a career-high 24 points. “And the way we did it — we kind of took it to them from the start to the finish.”

The neutral court at Cal State Fullerton proved conducive for a breakthrough, especially to open the second half, when the ’Bows worked it around to great effect during a 17-4 run.

The Rainbow Warriors face Seton Hall (2-2) of the Big East at 6:30 p.m. today in another ESPN2-televised game. The Pirates beat Grand Canyon 82-75 preceding UH’s win.

“We can’t be satisfied,” Stepteau said. “We’ll try to get another one tomorrow. That can’t be the peak of this trip.”

Against one of the largest teams in the country, UH’s 5-foot-9 point guard was at his best. Stepteau was in command of the court and sank 12 of 13 at the free-throw line, including several down the stretch once the Runnin’ Utes cut into UH’s 23-point lead and tried to play the foul game. He, fellow point guard Drew Buggs (10 points) and forward Jack Purchase (14 points, nine rebounds) each had five assists.

Eddie Stansberry came off the bench for 15 points. The shooting guard’s presence was felt most during the middle of the second half, when he sank four straight perimeter buckets for the ’Bows to build the lead to 61-39. Purchase’s 3 pushed UH’s lead to 23, its largest of the game, with 9:28 to play.

“We said from the start we’ve got to play aggressive,” coach Eran Ganot told Big West media. “We’re not very good when we’re on our heels. When we extended (the lead) to 10, 15, 20 points, it was staying aggressive.”

Sheriff Drammeh helped close it out once the Runnin’ Utes crept to within single digits, taking a couple of charges and sinking all six of his foul shots to finish with 11 points.

UH got off to an early lead, fell behind as its big men picked up fouls, but surged back up 31-24 with a 12-1 run. Stepteau completed a four-point play with 1:39 left in the half for a 37-28 lead. It was 39-31 at intermission.

Stepteau and Buggs combined for 18 points and seven assists to that point, shooting 6-for-8. Freshman 7-footers Mate Colina, Dawson Carper and Owen Hulland combined to shoot 5-for-5 in the period as UH converted 57.7 percent in the half.

The backup bigs helped overcome a scoreless game by starter Zigmars Raimo, who entered as the team’s leading scorer at 13.8 per contest. They were a combined 7-for-7, including 4-for-4 by Colina, against the only other team in the country featuring three 7-footers on its roster.

Utah’s best guard, Sedrick Barefield, was limited to four points on 1-for-8 shooting. Forwards Donnie Tillman and Riley Battin led the Utes with 16 points apiece.
