TUCSON, Ariz. (AP) - Aari McDonald scored 27 points on 10-of-15 shooting and No. 16 Arizona beat No. 8 UCLA 92-66 on Friday night.
Sam Thomas added 20 points as the Wildcats (17-3, 6-3 Pac-12) got off to a hot start, took a big lead and never allowed the Bruins back into the game.
McDonald, a junior guard from Fresno, California, has scored in double figures in all 57 games of her college career, the longest active streak in the nation. She has 10 20-point games this season.
Michaela Onyenwere had 17 points and 12 rebounds to lead UCLA (18-2, 7-2). Guard Charisma Osborne added 14 points.
Arizona's 92 points were by far the most scored against the Bruins in any game this season.

Arizona took a 27-16 lead into the second quarter with McDonald leading the way with 14 points.
Thomas knocked down three 3s in the second quarter, and the Wildcats led by as many as 20 points, despite just a pair of free throws and a layup from McDonald in the period.
UCLA struggled with Arizona's aggressive defense, committing nine first-half turnovers and 15 for the game. Kayla Owens hit a 3-pointer with 9 seconds left, helping UCLA cut its halftime deficit to 47-32.
The Bruins made it a 13-point game early in the third, but McDonald drove for another layup and was fouled. Her free throw gave Arizona 56-37 lead at the 7:53 mark.
UCLA went more than nine minutes without making a basket in the the third, and the Wildcats led by as many as 26 points.
McDonald received a standing ovation when she checked out of the game for good with 5:12 left to play.
