STANFORD (CBS/AP) — Bonnie Samuelson knocked down five 3-pointers on the way to 17 points all scored in the first half, and No. 6 Stanford beat Arizona 74-48 on Sunday to move closer to a 14th straight conference regular-season crown.

Chiney Ogwumike scored 11 of her 15 points during a decisive run late in the first half that put the game away for the Cardinal (24-2, 12-2 Pac-12), who clinched a bye into the quarterfinals of next month’s conference tournament in Seattle. They earned their 24th consecutive victory against the short-handed Wildcats.

Amber Orrange dished out nine assists to go with nine points and five rebounds in 24 minutes as coach Tara VanDerveer was able to rest her regulars for another long stretch given the lopsided result.

LaBrittney Jones scored 11 points for Arizona (5-20, 1-13), which went cold in the first half and couldn’t recover against the dominant play of Stanford on both ends of the floor.

Jones was the only player to reach double figures in Stanford’s weekend games against Arizona and No. 15 Arizona State, which lost 61-35 at Maples Pavilion on Friday night.

Ogwumike shot 7 for 12 and grabbed nine rebounds in 22 minutes, getting a nice break for the second straight game. She didn’t lead the team in scoring for only the second game all season.

Stanford found its shooting touch again against Arizona and held a 42-28 rebounding edge in the teams’ second meeting of the season after the Cardinal won 96-52 behind a season-high 15 3s last month on the Wildcats’ home floor in Tucson. Injury-plagued Arizona had only six healthy players after senior guard Carissa Crutchfield sprained an ankle in a 63-49 loss at California on Friday night and hobbled in a walking boot.

With the Cardinal 9 for 45 on 3-point attempts the past two games — including 0 for 4 in Friday’s win against Arizona State — Samuelson kept the pressure on the Wildcats from the perimeter in this one. She shot 5 for 8 from beyond the arc and was one 3-pointer shy of matching her career high.

Stanford made three quick 3s early in the second half, by Orrange, Taylor Greenfield and Lili Thompson, and Arizona called timeout down 61-21 with 15:50 remaining.

Arizona made 5 of its initial 7 shots to keep things close early before a long drought did the Wildcats in for good. Trailing 11-8, Thompson scored four straight points followed by four in a row from Ogwumike as Stanford got rolling with a 28-2 run to go ahead 36-13. The Wildcats missed 15 straight shots during that 10 1/2-minute stretch before Candice Warthen’s basket at 4:24.

Samuelson hit four straight 3s late in the first half as the Cardinal led 48-19 at intermission behind 51.4 percent shooting (18 for 35) with 10 3-pointers.

Arizona made only seven field goals in the first half and shot 31.5 percent overall, missing all five of its 3-point tries.

Stanford freshman Karlie Samuelson sat out with a foot injury as a precaution.
