Joslyn Tinkle and Stanford have won 17 straight games since their only loss of the season.
This balanced blowout was one of the easy ones.
Tinkle had a career-high 22 points and matched her career best with 11 rebounds, and the Cardinal had five starters score in double figures in a 91-51 victory over Arizona on Saturday.
Stanford (20-1, 11-0 Pac-12) hasn't lost since Nov. 4 at Connecticut. But the previous two victories were close ones. First, there was a 74-71 overtime win at home against California a week ago. Then Stanford was tied at 40 with Arizona State on Thursday night before pulling away to a 62-49 win.
''The past few games we've not played to the best of our abilities,'' Tinkle said. ''We know what we're capable of and we haven't pushed ourselves there. We really knew coming into this game what we had to do to prove to everyone, to prove to ourselves, that we are more capable and we can reach to a higher level.''
The Cardinal hit their first five shots and made 57 percent of their first-half attempts in taking a 51-31 lead at the break.
''When your teammates get going and you're happy for them and you're happy for yourself, you get that confidence,'' Tinkle said. ''Obviously hitting those shots gave us a confidence boost and from there we didn't let up.''
Stanford beat the Wildcats for the 21st time in a row, a streak that dates to 2004.
''We've kind of been playing people closer than we wanted to,'' Stanford coach Tara Vanderveer said. ''I like the fact we were able to get everybody in and everyone contributed.''
Chiney Ogwumike scored 18 points for the Cardinal, and her sister Nnemkadi finished with 15. Toni Kokenis added 11 points and Amber Orrange had 10.
Stanford shot 50 percent and held Arizona to 29.5 percent shooting.
Vanderveer was pleased with the scoring balance.
''This is great momentum for us,'' she said. ''We've got a long way to go but I'm really excited about getting major contributions from different people. We depend a lot on Nnemka and Chiney and it's great to have Jos play so well. Nnemka and Chiney are so unselfish and so excited about other people doing well. They're really special.''
Candice Warthen led the Wildcats (13-10, 2-9) with 13 points. Shanita Arnold added 10 points and Aley Rohde had nine points and 11 rebounds.
The Wildcats lost their sixth in a row. Unlike Thursday's loss, the previous five had been by 10 points or less, two of them in overtime.
Arizona was down 13-7 when the Cardinal went on an 18-2 run to go up 31-9 on Chiney Ogwumike's rebound basket with 9:55 left.
Kokenis sank a 3 to start the second half, sparking a 25-5 outburst en route to Stanford's most one-sided conference win of the season. Orrange was 5 of 5 from the field and Kokenis had five steals.
''If you make mistakes, they are going to capitalize right away,'' Arizona coach Niya Butts said. ''They just do everything well.''
Tinkle, a 6-foot-3 junior from Missoula, Mont., was averaging 7.1 points and 4.9 rebounds before the game. Her previous career best was 20 points twice, most recently against Colorado on Jan. 14.
Tinkle made 8 of 15 shots, including 3 of 4 3-point attempts. The bigger, more athletic Cardinal had a 22-5 advantage in second-chance points.
Arizona was without leading rebounder Erica Barnes, who sat out her third game in a row with a concussion.
The Wildcats last beat Stanford 88-83 on Feb. 5, 2004.
