NORMAN, Okla. (AP) -- Cameron Clark's 14 points led five Oklahoma players in double-figure scoring as the Sooners turned in their best defensive effort of the season and raced past Idaho 85-65 Wednesday.
Idaho (1-1) scored on its first three possessions, including a pair of 3-pointers. After the teams swapped the lead four times Idaho built a six-point lead before Oklahoma moved ahead for good with 7:56 remaining in the first half.
"It was a good game to win," Oklahoma coach Lon Kruger said. "I thought Idaho is a ball club that does a real good job of executing and controlling the game. "Our guys -- after the first few minutes -- got into it and started dictating defensively."
Oklahoma (3-0) shot 48 percent from the floor in the first half and scored seven points off nine Idaho turnovers to lead 40-29 at halftime.
Oklahoma picked up the pace defensively in the second half, forcing the Vandals to work through full-court pressure most trips up the floor. The Sooners pushed their lead to as many as 26 while forcing five more turnovers and holding a 45-35 rebounding edge.
The Sooners also recorded a season-high eight blocks in a tightly-officiated game. The two teams combined for 45 fouls and 54 free throws.
The 65 points were the fewest the Sooners have allowed all season.
"We were a little more aggressive," Kruger said. "That's the key. We slid our feet much better on the ball and we went to the ball much better. Everyone is still learning. The officials are still learning. The players are still learning how the game will be called and this one was probably a little tighter with hands than the other two."
Buddy Hield and Ryan Spangler scored 13 for the Sooners while Tyler Neal and Je'lon Hornbeak each added 12.
Glen Dean led Idaho with 14 points. Sekou Wiggs scored 11.
Idaho came into the game leading the WAC conference in 3-pointers made (7) and three-point percentage (36 percent). After guard Connor Hill opened the game with a pair of threes, Idaho would finish the night converting just 6-of-22 attempts.
"Yesterday's practice was mainly about defense," Hornbeak said. "We watched a lot of film defensively and it's always good to see your mistakes together. We really held each other accountable and it showed."
Neal again came off the bench to give the Sooners solid production, leading Oklahoma with seven rebounds in 19 minutes.
The game was Oklahoma's third in six days since beginning the season Nov. 8 with an 82-73 win over Alabama in the Buckets and Boots Showcase. The Sooners returned home Monday to beat North Texas 95-82.
Oklahoma will have eight days off until traveling to Brooklyn, N.Y., to take on Seton Hall Nov. 22 in the Coaches vs. Cancer Classic.
