CORVALLIS — Jared Cunningham scored 22 points and Roberto Nelson added 14 to lead Oregon State to a 74-54 win against Illinois-Chicago on Wednesday night.

In their final tuneup before Pac-10 Conference play, the Beavers (5-6) led by 20 at halftime, and Illinois-Chicago got no closer than 17 afterward.

Robo Kreps had 21 points and seven rebounds, and Paul Carter scored 19 points for the Flames (5-8), who defeated then-12th ranked Illinois four days earlier.

Nelson, a redshirt freshman guard, had the best of his four games as a collegian. After 18 months in eligibility limbo, the highly-touted recruit from Santa Barbara, Calif., was finally cleared by the NCAA earlier this month.

The Beavers, who lost four of its previous five games, used a 7-0 run during in the first six minutes of the second half to build a 51-26 advantage.

Cunningham added the exclamation point late with a dunk off a long outlet pass from Devon Collier, giving the Beavers a 69-45 lead with 3:54 remaining.

Oregon State shot 27 of 58 from the floor, while Illinois-Chicago was 19 of 57.

The Beavers, who entered the game second in the country in steals with 11.9 per contest, had nine.

Nelson scored seven straight points to give Oregon State a 16-6 lead. The Beavers went on a 12-0 run to go ahead 30-9.

Washington 90, Nevada 60

At Seattle, Isaiah Thomas scored a season-high 24 points, and Washington looked sharp in its last warmup before beginning Pac-10 play.

Thomas did a little of everything, as the Huskies finished out almost all of their nonconference slate at 8-3, the only losses coming to Kentucky, Michigan State and Texas A&M by a combined 13 points. Washington has one nonconference game remaining on Feb. 22 against city rival Seattle.

Once again Thomas, the Huskies leading scorer at 15 per game, got plenty of help. Matthew Bryan-Amaning added 16 points and could have scored a lot more if not for a number of close misses.

Washington led by as many as 37 in the second half.

Dario Hunt led Nevada (3-9) with 16 points and 14 rebounds.

Arizona 82, Robert Morris 56

At Tucson, Ariz., Derrick Williams had 17 points and nine rebounds, Jesse Perry added 16 points in his first career start and Arizona finished off its best nonconference season in a decade.

Arizona (11-2) blew open a tight game with a 19-4 run spanning halftime and hit nine 3-pointers against one of the nation's best perimeter defenses to win 11 nonconference games for the first time since 1999-2000.

Kyle Fogg added 11 points and the Wildcats can enjoy the holidays with eight days off before opening Pac-10 play at Oregon.

Washington State 83,Mississippi State 57

At Honolulu, Klay Thompson scored 28 points to lead Washington State past Mississippi State in the opening round of the Diamond Head Classic.

Thompson was 10 of 20 from the field, and Faisal Aden came off the bench to score 20 points for the Cougars (9-1), who won their fourth straight.

The Bulldogs (7-4) held a 40-39 lead at halftime, but Washington State used a 14-0 run early in the second half to take a 57-45 lead and pull away for good.

No. 3 Kansas 78, California 63

At Berkeley, Calif., Markieff Morris had 21 points and 10 rebounds and Kansas overcame the ejection of his twin brother to beat California.

Freshman Josh Selby scored 18 points in his second game since an NCAA suspension and the Jayhawks (11-0) remained unbeaten and handed the Golden Bears (6-5) their third loss in four games.

This marked Kansas' 10th straight win over Cal. But instead of being remembered for Selby's sweet outside shooting or Morris' strong play inside, this one will be remembered for the chippy second half that featured one flagrant foul, Marcus Morris' ejection and three technical fouls.
