STANFORD -- The Pac-12 Conference looked dramatically different Sunday in the rubble of fifth-ranked Stanford's ungainly 67-55 defeat to seventh-ranked Cal.
It's no longer the Cardinal's domain where women's basketball is concerned.
Cal (13-2, 3-1 Pac-12) made sure of that in front of 5,931 fans at Maples Pavilion with a resounding upset that ended Stanford's 81-game conference win streak.
In the Cardinal's first game at Maples since Connecticut ended its 82-game home win streak last month, Stanford was not up to the challenge.
Not even close.
"They are extremely aggressive," Stanford coach Tara VanDerveer said of Cal. "If there is one thing we're not, it is aggressive."
The Bears mauled
They did it while shooting a season-low 29.7 percent from the field.
Point guard Brittany Boyd led Cal with 19 points as the Bay Area schools met for the second time in a week. Gennifer Brandon had 14 points and 12 rebounds.
The last time the Cardinal lost a conference game came four years ago with 57-54 defeat in Berkeley.
"We beg and beg the Pac-12 to step up, so this is a good thing in a bad way for us," VanDerveer said.
The Bears looked possessed after losing Tuesday to Stanford 62-53 in Berkeley. Cal coach Lindsay Gottlieb didn't shy away from the
The review provided some serious food for thought.
"The take-away is if we can play at this level all the time, then you're talking elite," Gottlieb said.
In ending a 10-game losing streak to its rival, Cal ushered in a new competitive spirit for the Pac-12.
This much is certain: Brittle Stanford is far from invincible at home.
The Cardinal plays No. 14 UCLA on Friday as part of a five-game homestand that also includes No. 23 Colorado. UCLA visits Cal on Sunday.
The last time Stanford lost three in a row at home was in VanDerveer's second season in 1986-87.
The Cardinal coach said some might wonder which team will show up on any given night because Stanford has upset then-No. 1 Baylor and is undefeated on the road this season.
"In some ways we overachieved early," she said, adding the success might have led some players to think they are better than they are.
"This is a character-building year," added junior forward Chiney Ogwumike, who led Stanford with 18 points and nine rebounds.
Although Ogwumike continues to prove she is one of the nation's marquee players, Stanford isn't giving
Cal exposed the Cardinal backcourt Sunday by forcing 16 Stanford turnovers to Cal's six.
Boyd had plenty of help from Mikayla Lyles, a 5-foot-8 junior from Pleasanton. She matched a career high with 14 points in the first half, propelling Cal to an eight-point lead at the intermission.
While trailing 47-39, the Cardinal failed four times to close within six points and then paid for it. Layshia Clarendon buried a 3-pointer and Boyd made two free throws to boost the margin to 13 points with 10:14 to play.
It didn't start out that way with the Bears missing their first nine shots.
Boyd didn't panic.
"The main thing we said was keep on punching, keep on fighting," the Berkeley High graduate said.
In the end, Stanford never knew what hit it.
