PULLMAN, Wash. (AP) -- Ivory Clark had bad memories of Washington State's overtime loss to Stanford last month.
Clark wanted to ensure Thursday night's game didn't come down to another last-second shot. He had 11 points, 10 rebounds and five blocks to help No. 14 Washington State beat No. 25 Stanford 58-45 and stay in second place in the Pac-10 conference.
He also held Lawrence Hill, Stanford's leading scorer, scoreless with 10 missed field goals. Hill came in averaging 16 points.
"I wanted to take it upon myself to put the clamps down on those guys," Clark, the Cougars' lone senior, said. "I still had memories of Goods hitting that shot, and I didn't want to come close to it."
The Cougars didn't. They held Stanford to just eight points during a 19-minute stretch over the first and second halves to take control. They held the Cardinal to 28 percent shooting, blocked a team record 12 shots, and added 7 steals.
The 45 points were a season low for Stanford, which came in averaging 72 and had won six of its past seven Pac-10 games to move into third place.
"They were flat better than us in all aspects," Stanford coach Trent Johnson said. "There was no question about it."
Washington State (20-4, 9-3) reached 20 wins for the first time since the 1993-94 season.
"To get 20 wins, that's noteworthy," said first-year coach Tony Bennett. "We are in a good spot in the Pac-10."
Indeed, players were asked if it was too early to dream about the first Pac-10 title in the program's history, especially for a team that was forecast to finish last.
"I think about it every night," Clark said. "It's a very realistic goal for us."
Stanford (15-7, 7-4) was led by Brook Lopez's 13 points. Goods, who had 30 in last month's 71-68 overtime win, was held to 11 this time.
The Cardinal were doomed by a prolonged drought, scoring just 8 points over the final 8:40 of the first half and the first 10 1/2 minutes of the second half.
"We were lazy," said Stanford's Fred Washington. "We stopped doing what we had done to get where we are. We took a step back tonight, a gigantic step back."
After leading 22-20 at halftime, Washington State jumped to a 30-21 lead as Stanford missed its first seven shots of the second half and did not make a field goal in the first 7 minutes.
Goods' 3-pointer with 9:17 left cut Washington State's lead to 33-27, and was only the Cardinal's second basket in 12 shots in the half.
The pace picked up after that, and Daven Harmeling's 3-pointer and Cowgill's putback built a 39-29 lead for the Cougars with 5:52 left.
The Cardinal could not cut into that lead.
In the first, Stanford jumped to a 16-8 lead, but then was held scoreless for nearly seven minutes. Clark's 3-point play capped a 7-0 run that brought the Cougars within 16-15.
Washington's free throw made it 17-15, but Clark's layup tied it at 17 with 4 minutes left. Weaver made a basket and Low a 3-pointer for a 22-17 WSU lead that completed a 14-1 run.
Landry Fields' 3-pointer for Stanford cut Washington State's halftime lead to 22-20, and was their only field goal in the final 11:20 of the first.
Washington State shot 39 percent in the game. The Cougars allow only 58 points per game to lead the Pac-10.
Washington State reached 20 wins for the first time since the 1993-94 team went 20-11.
Weaver, who like the rest of the Cougars enjoyed just 12 wins and 11 wins the past two seasons, took a moment to reflect on the 20th win.
"Just hearing that, 20 wins," he said. "It's a good feeling for us. Tonight was a good win, we took another step forward.
