Portland, Ore. ? Ronny Turiaf scored 21 points and grabbed 14 rebounds to lift No. 15 Gonzaga to its eighth straight victory, 80-65, Friday night over Portland.

Blake Stepp added 19 points and nine assists for the Bulldogs (15-2, 5-0 West Coast Conference), who put together a 19-6 run at the end of the game to turn away the Pilots.

Eugene Jeter scored 18 points for Portland (8-10, 2-3), which toppled Gonzaga last season. Donald Wilson added 15 points for the Pilots, who put up 17 more shots than the Bulldogs but made just 36 percent.

Stepp hit 10 of 10 free throws for Gonzaga, which has won 15 of 16 against the Pilots. Cory Violette had 17 points and eight rebounds.

Portland was within two points late in the second half, but Gonzaga muscled the ball down low to Turiaf and Adam Morrison for scores and turned the Pilots away four straight times at the other end.

Violette fed Stepp for an 8-footer in the lane to make it 71-61 with 3:27 left, and Kyle Bankhead hit a 3 from the corner with 2:29 remaining to seal it.

Turiaf took control inside in the second half. The 6-foot-10 forward born in LeRobert, Martinique, scored 11 of the Bulldogs’ 16 points over an eight-minute span. But Jeter kept the Pilots in the game, hitting back-to-back 3s to pull to 61-59 with 8:47 left.
