OGDEN -- Weber State wore its retro uniforms, then provided Portland State with an old-school beating.
The Wildcats reeled off their 10th straight victory, defeating the Vikings 80-52 on Thursday night at the Dee Events Center behind 19 points from Davion Berry and double-doubles by Scott Bamforth and Joel Bolomboy.
Bamforth finished with 13 points and 12 rebounds, while Bolomboy came off the bench to add 10 points and 11 boards.
With the school selling 50-cent upper bowl tickets to celebrate 50 years of Division I basketball at Weber State and a holding a '60s costume contest to go with their old-school unis, the Wildcats quickly left the Vikings in the past.
Weber State (23-5, 17-2 Big Sky) dominated Portland State (8-19, 5-14) by a margin of 44-23 on the glass and led by as many as 28 points in the first half, when the Vikings looked like someone had put them out to sea and shot a flaming arrow on to their longboat.
Portland State shot 18.2 percent and scored 13 points in the first half, a season-low for a Weber State opponent.
"I thought that first half, we played like we practiced. We had two really good practices this week," Weber State coach Randy Rahe said. "We kept it short, about an hour and 10 minutes, but we had really good energy, really good enthusiasm, really good spirit and it really carried over to that first half, how we started the game."
The Wildcats, who came into the game ranked first in the country in 3-point shooting at 43.1 percent, opened on a 12-0 run, with three 3s from Richardson and another trey from Bamforth before PSU got on the board.
Weber State hit 8 of 16 from beyond the arc in the game to improve on its average, while shooting 55.8 percent overall from the field, where they were ranked second in the country before the game at 51.0 percent.
Bolomboy, the freshman forward, was 4 for 6 from the field while carrying over his aggressive play from the past few games.
"I've gained more confidence and my teammates are giving me the ball more," he said. "Coaches are telling me to score, I can score the ball, so I take the open shots I get."
Bamforth had a career-high 12 rebounds.
"We were all just trying to rebound," the senior shooting guard from Albuquerque, N.M., said.
"If we've got five guys crashing on defense, hopefully one of us gets it because they don't usually send five guys ... so we should get every rebound on defense.
"Me personally ... I'm only 6-1 and a half, whatever, but I try and go get every one."
Portland State brought the lead back to 17 points with 7:28 remaining, dramatically improving their field goal shooting to 59.3 percent in the second half, but an 11-0 run put the Wildcats back up to a comfortable 20-plus point margin.
PSU took Weber State to overtime in December, but they never seriously challenged the 'Cats on Thursday.
"We asked our team, I need 13 energy givers and no energy takers," Rahe said. "Our team's been energy givers."
The second-place Wildcats still have a chance to claim the regular-season championship and host the Big Sky Tournament, but they need a lot of help: First-place Montana would have to lose at home on Saturday to Northern Arizona, while Montana State would also have to lose to Sacramento State and the Wildcats have to win.
Weber State plays its regular season finale Saturday on Senior Night against Eastern Washington. The Wildcats will honor former coaches and players at halftime while celebrating the 50th anniversary of Division I basketball at the school.
* MONTANA 63, SACRAMENTO STATE 52: At Missoula, Jordan Gregory scored 21 points as Montana maintained its hold on first place in the Big Sky Conference with a victory over Sacramento State.
The Grizzlies (22-6, 18-1 Big Sky) lead Weber State by one game in the conference standings with one game remaining in the regular season.
Kareem Jamar added 12 points for Montana, which played again without starters Will Cherry and Mathias Ward because of foot injuries. Cherry, the team's leading scorer, has missed the last three games and is also expected to sit out the regular-season finale Saturday against Northern Arizona. Ward, who was hurt Feb. 16, had surgery this week and is out for the season.
John Dickson led Sacramento State (14-14, 8-11) with 15 points.
The Vikings, one of four teams still fighting for the final three spots in the seven-team Big Sky tournament, finish the regular season Saturday at Montana State.
* NORTHERN COLORADO 66, SOUTHERN UTAH 58: At Greeley, Colo., Derrick Barden had 18 points and 10 rebounds as Northern Colorado clinched a spot in the Big Sky tournament with a victory over Southern Utah.
The Bears (12-17, 10-10 Big Sky), who wrapped up their regular season, are in fourth place in the conference and can finish no lower than fifth once the remaining Big Sky teams conclude their season on Saturday. The top seven teams advance to the conference tournament.
Tevin Svihovec added 14 points for Northern Colorado, Tate Unruh had 13 and Connor Osborne 11. The Bears shot 50 percent overall despite making just 3 of 15 3-pointers. They were 17 of 26 from the free-throw line compared to 4-of-6 foul shooting for Southern Utah.
Jackson Stevenett had 25 points for the Thunderbirds (11-18, 8-11), who conclude the regular season Saturday at North Dakota and are still fighting for one of the remaining spots in the Big Sky tournament.
* MONTANA STATE 83, NORTHERN ARIZONA 79 (OT): At Bozeman, Mont., Antonio Biglow scored 27 points to help Montana State hold on for a9 victory in overtime over Northern Arizona.
Montana State (12-16, 9-10 Big Sky) also got 19 points and 12 rebounds from Paul Egwuonwu, 18 points and nine rebounds from Flavien Davis and 11 points from Christian Moon. Biglow also had seven steals.
Northern Arizona (11-19, 8-11) was led by Gabe Rogers, who scored 29 points, including seven 3-pointers. Stallon Saldivar scored 14 points and Max Jacobsen had 12.
* LOYOLA MARYMOUNT 61, SAN FRANCISCO 60 (OT): At Las Vegas, Anthony Ireland scored 16 points, including two big free throws late in overtime, and Loyola Marymount continued its surprising West Coast Conference tournament run.
Ireland scored all four LMU points in the extra session before Taylor Walker's free throw gave the Lions (10-22) a 61-57 lead with 9 seconds left. San Francisco's Cole Dickerson made a meaningless 3-pointer in the closing seconds to complete the scoring.
Godwin Okonji had 14 points and 10 rebounds for ninth-seeded Loyola, which entered the tournament on a 14-game losing streak before beating eighth-seeded Portland on Wednesday. Ashley Hamilton chipped in 11 points and 14 rebounds.
Dickerson had 23 points and 18 rebounds for the No. 5 seed Dons (14-16), and his tip-in with 9 seconds left sent the game to overtime.
LMU will face No. 4 seed Santa Clara in the quarterfinals Friday.
* COLORADO 76, NO. 19 OREGON 53: At Boulder, Colo., Xavier Johnson had a career-high 22 points, Spencer Dinwiddie added 17 and Colorado beat No. 19 Oregon, completing a season sweep and thwarting the Ducks' bid to gain a share of the Pac-12 Conference title.
The Buffaloes (20-9, 10-7) played without the nation's leading rebounder, Andre Roberson, who sat out with a viral illness. Gone with the athletic junior forward were 11.5 rebounds and 10.8 points a game.
Arsalan Kazemi, Jonathan Loyd and Ben Carter each had 10 points for Oregon (23-7, 12-5), which fell into a first-place tie with UCLA. The Ducks hold the tiebreaker after beating the Bruins in their only meeting in January.
Oregon can wrap up at least a share of their first league crown since 2002 -- along with the No. 1 seed for the Pac-12 tournament -- with a win at Utah on Saturday.
