Bryce Pressley's voice was totally gone by the raucous postgame celebration after Portland beat the No. 22 Bulldogs 82-73 on Thursday night.
The victory snapped a 20-game losing streak to Gonzaga.
The last time Portland (10-7, 2-3) won at home against Gonzaga was in 1996, and the Pilots' previous victory in the series came in 2003 in Spokane. Portland had not defeated a ranked opponent since 2009 against then-No. 22 Minnesota.
Gonzaga (14-3, 4-1) had won four straight to open the conference season after a 72-62 loss to Kansas State on Dec. 21.
