Kennedy again turned the ball over on the inbound pass, and Stanford called a timeout with 16 seconds left.

A drive to the hoop by Spencer Jones ended with a missed attempt with three seconds left.

A midcourt heave from Cal's Jaylon Tyson was off the mark.

Cone topped the Golden Bears with 19 points and added five assists. Tyson had 18 points, eight assists and seven rebounds, and Jalen Celestine finished with 14 points.
