Stanford snapped defending national champion Baylor's 42-game winning streak Friday, winning 71-69 when player of the year Brittney Griner missed a short turnaround at the buzzer.
Griner scored 18 of her 22 points in the second half, helping the Lady Bears rally from a 14-point deficit in the first half. Her shot at the buzzer bounced off the rim and Stanford celebrated the victory. It was the Lady Bears' first defeat since losing to Texas A&M in the regional finals of the 2011 NCAA tournament. Baylor went 40-0 last year.
Chiney Ogwumike scored 18 points to lead the fourth-ranked Cardinal (3-0), who lost to Baylor in the national semifinals last season by 12 points. Her reverse layup gave Stanford a four-point lead with 22 seconds left.
Destiny Williams responded with the first 3-pointer of her career to pull Baylor (2-1) within one.
Toni Kokenis made one of two free throws. Baylor got the rebound and advanced the ball to halfcourt before calling timeout to set up the final play.
It was the fifth-longest winning streak in NCAA women's history. Stanford also ended UConn's NCAA record 90-game run in 2011.
Baylor was the heavy favorite to repeat as champion with their entire starting five back from last season. The Lady Bears cruised to an easy 89-51 victory over No. 6 Kentucky on Tuesday before heading to Hawaii for the three-game Rainbow Wahine tournament.
Baylor had to play the last 35 minutes of the game without preseason All-America guard Odyssey Sims, who strained her hamstring early in the first half.
Without their playmaker, the Lady Bears fell down by 14 points before rallying to 31-29 at the break.
