LOS ANGELES (Ticker) -- Despite Nate Robinson's inability to come through in Pac-10 Conference games, No. 14 Washington had little difficulty extending its longest winning streak since 1982.

Tre Simmons scored 22 points and Mike Jensen added 14 as Washington won its ninth straight game, an 84-59 triumph over Pac-10 Conference rival Southern California.

A Player of the Year candidate, Robinson leads the Huskies with an average of 17.7 points per game this season. But in two previous conference battles this season, he has totaled just 19 points.

In this one, Robinson scored five points in the first half and added just three in the final 20 minutes. But his teammates picked up the slack as Washington (13-1, 3-0 Pac-10) extended a 36-19 halftime lead with 48 points in the second half.

"Nate Robinson took nine shots, but his shot wasn't falling," Huskies coach Lorenzo Romar said. "It's a compliment to Nate. He looked to give it off because his shot wasn't falling."

The winning streak is the longest for the Huskies since capturing 10 straight in 1982.

Simmons scored 12 points in the second half while Jensen chipped in 10 over the opening 20 minutes.

"We are a veteran team, they are younger," Simmons said. "We had to play like a veteran team. All in all, we did a good job."

Brandon Roy scored 10 points and Bobby Jones added eight for the Huskies, who have reached the 13-win mark faster than any Washington team since the 1975-76 club opened the season with 14 straight victories.

Nick Young had 20 points and seven rebounds and Lodrick Stewart scored 10 - including the first seven of the game - for the Trojans (7-7, 0-3), who committed 17 turnovers in the first half.

"Their pressure really bothered us. We couldn't run our offense at all," USC coach Jim Saia said. "This was just a bad matchup for our team. We're not as quick as they are. It was just an old-fashioned blowout."

Washington set the tone from the onset, scoring the first 10 points of the game, including six by Jensen. Leading by five midway through the first half, the Huskies went on a 15-2 run to build a 30-12 advantage.

"They came out with the mind set that we were weak," Young said. "We have a lot of talent on this team. We just don't know how to get it together."

Simmons and Robinson each scored five points during the spurt.

Washington began the second half with a 10-3 burst, but USC scored eight straight points to pull within 46-30 with 15:28 remaining.

"You always feel in the second half, they're going to give you a shot in the first five minutes," Romar said. "We did a good job defensively, lots of pressure. It was hard for them to make good passes."
