Elias Harris scored 17 points and No. 3 Gonzaga crushed visiting Santa Clara 85-42 on Wednesday night, the ninth win in a row for the Zags.

Kelly Olynyk added 15 points for Gonzaga (26-2, 13-0 West Coast), which is riding its best ranking in the poll ever.

Brandon Clark led Santa Clara (19-9, 7-6) with 14 points. Leading scorer Kevin Foster was saddled with three fouls in the first half and finished with just four points, 14 below his average.

"It was a rough performance all around," Santa Clara coach Kerry Keating said. "You make it hard on yourself when you're not competing defensively."

"This is always a tough place to play," Keating added.

Gonzaga needs one more victory to claim at least a share of the WCC regular season title it lost last season. The Broncos are battling to finish in the top four to earn a bye into the quarterfinals of the WCC tournament next month.

Santa Clara averages 75 points per game and had not scored fewer than 60 points in a game all season. The Broncos lost 81-74 at home against Gonzaga.

But cold shooting did them in.

Santa Clara hit the first basket of the game, then watched Gonzaga score 15 straight points over the next 6 minutes to take control.

"They outscored us, outrebounded us and outplayed us," Keating said. "They solidified their position as one of the best teams in the country."
