SPOKANE — Unheralded North Dakota gave No. 12 Gonzaga all it could handle on Saturday night.
Josh Perkins scored 20 points and Zach Norvell Jr. added 19 as the Bulldogs pulled out an 89-83 win in overtime.
Johnathan Williams added 14 points for Gonzaga (9-2).
"We were lucky that game was at home," Gonzaga coach Mark Few said.
"We let them get some belief," Few said of the early portions of the game. "They outhustled us."
Gonzaga, which came in ranked second in the nation in field goal percentage, shot terribly for much of the game. The Bulldogs were shooting in the 30s for most of the first half, as North Dakota built a 34-30 halftime lead.
"We had an offensive problem and that affected our defense," Few said. "We've been working on our press. That really helped us tonight."
Geno Crandall scored 28 for North Dakota (4-7), which is struggling this season after qualifying for the NCAA Tournament last season. Cortez Seales added 23 on 11-of-15 shooting.
S. UTAH 86, C. MICHIGAN 41: Brandon Better scored 17 points, Ivan Madunic and James McGee 16 points each and Southern Utah (6-4) made a 14-2 opening run after halftime stand up at home to snap the Chippewas' seven-game winning streak. Led by 21 points from Cecil Williams, Central Michigan (8-2) clawed back within three, but never regained the lead.
WEBER ST. 96, ARK.-PINE BLUFF 74: Jerrick Harding poured in 30 points and Weber State snapped a three-game skid with a romp at home over winless Arkansas-Pine Bluff. Harding hit 9 of 13 shots from the floor, including 4 of 5 from 3-point range, and 8 of 9 free throws for the Wildcats (5-5). Martaveous McKnight paced the Golden Lions (0-12).
PORTLAND ST. 116, LINFIELD 71: Deontae North scored 27 points and had five steals as Portland State defeated visiting Division III Linfield College, turning 27 turnovers into 33 points. The Vikings (9-3) lost a four-game win streak at Oregon but rebounded with 51 percent shooting (40 of 78) with 18 3-pointers and 21 steals against the smaller Wildcats (7-3).
