SPOKANE, Wash. (AP) -- Jeremiah Dominguez scored 25 points and Portland State upset No. 7 Gonzaga 77-70 on Tuesday night for its first win over a ranked team since it reinstated its basketball program for the 1996-97 season.
Portland State, which is 1-11 against nationally ranked teams, broke a 10-game losing streak to Gonzaga.
Gonzaga (8-3) was coming off an 88-83 overtime loss to No. 2 Connecticut in Seattle on Saturday that resulted in the Bulldogs rising one spot in the Top 25. But they looked sloppy against the Vikings, committing 11 turnovers, missing layups and shooting only 42 percent.
It was the Zags' third home loss in 58 games since the McCarthey Athletic Center opened in 2004.
The Vikings, the defending Big Sky Conference champions, endured a roundabout trip to Spokane after winter storms closed a portion of Interstate 84. They bused up to Seattle and then across the state to Spokane, arriving Tuesday.
The teams exchanged the lead most of the second half.
Portland State again threw the ball away and Pargo grabbed the inbounds pass, slammed it home and was fouled. His three-point play gave Gonzaga a 68-67 lead with 2:16 to go.
Waters' runner tied the score at 69 with 1:45 left.
Gonzaga turned the ball over on a possession arrow after Heytvelt's shot stuck against the rim.
Phil Nelson's 3-pointer gave Portland State a 72-69 lead with 44 seconds left. Pargo missed on the other end, and Portland State rebounded and Waters was fouled with 30 seconds left, making both for a 74-69 lead.
Gonzaga's last home loss was to Washington State last season and they had won 10 straight at home since.
