Kari Korver scored 11 points, hitting three 3-pointers in the decisive third quarter, and No. 20 UCLA led all the way in beating 12th-ranked Stanford 56-36 Sunday night, snapping the Bruins’ 21-game skid against the perennial Pac-12 powerhouse.

Monique Billings had 12 points and seven rebounds and Nirra Fields added 11 points for the Bruins (14-5, 6-2 Pac-12), who held the Cardinal to a season-worst 20 percent shooting. UCLA moved into a tie with Washington for third in the conference.

It was the Bruins’ first victory over Stanford since Jan. 4, 2008, when they won 69-56 at Pauley Pavilion. They earned a sweep of the Bay Area schools for the first time since 2006 and just the fifth in school history, having beaten California 75-56 on Friday.

Erica McCall had nine points and 11 rebounds for the Cardinal (15-5, 5-3), which has no senior starters for the first time in over a decade. They never got closer than two points early in the second quarter.

UCLA dominated the third, outscoring Stanford 20-13 behind three 3-pointers by Korver and another by Fields, who had seven points in the period. The Bruins limited the Cardinal to just three field goals while building their largest lead of 23 points.

Billings’ defense helped contain McCall, who was coming off her 11th double-double of the season in a 10-point win over Southern California on Friday night. McCall was held to single-digit scoring for just the fourth time.

UCLA maintained its defensive energy in the fourth. Lili Thompson took off on a fast break, but Fields came up with a big block at the other end, grabbed the defensive rebound and found Billings, whose layup extended UCLA’s lead to 53-30.

The Bruins held Stanford to 23 percent shooting in the first half, when they lead 28-14 at the break.
