Portland State made a tough trip more than worth the trouble by coming up with the biggest win in its history.

The Vikings fought their way through the weather-plagued Northwest, arriving just hours before they beat No. 7 Gonzaga 77-70 on Tuesday night, their first win over a ranked team since reinstating its basketball program in 1996-97.

"This is a big statement for us," said 5-foot-6 senior Jeremiah Dominguez, who led Portland State (9-3) with 25 points. "This program is building."

The Vikings had lost their last 10 meetings with Gonzaga (8-3) and came in 0-11 against ranked opponents.

The game almost wasn't played because of the snowstorm that has snarled travel throughout the Northwest. Because of flight cancellations and highway closures, Portland State took a roundabout route to Spokane.

They bused to Seattle and stayed overnight in the suburbs. Then they bused across the state and arrived in Spokane about 3Z\x hours before game time. Even though they didn't have time for a shootaround, the Vikings still ended up shooting 45.9 percent.

"Maybe that's the way to do it," Portland State coach Ken Bone joked. "This game was very close to not being played."

In other games involving ranked teams on Tuesday, it was: No. 9 Texas 74, Wisconsin 69; No. 12 Georgetown 76, Florida International 38; No. 13 UCLA 113, Wyoming 62; Butler 74, No. 14 Xavier 65; No. 20 Arizona State 90, Idaho State 55; No. 23 Minnesota 80, Southeastern Louisiana 71; and Illinois 75, No. 25 Missouri 59.

Dominguez was 7-of-10 from 3-point range and the Vikings were 12-of-31 as a team. Phil Nelson hit the last of the 3s with 44 seconds left to give Portland State a 72-69 lead. Jeremy Pargo missed for Gonzaga and Dominic Waters made two free throws for the Vikings.

Portland State, the defending Big Sky Conference champions, outrebounded the taller Zags 39-30, held them to 42 percent shooting and forced them into 11 turnovers.

"We were not in awe of Gonzaga," Bone said.

The Bulldogs were coming off an 88-83 overtime loss to No. 2 Connecticut in Seattle on Saturday.

"We got what we deserve," Gonzaga coach Mark Few said.
