Winslow, a trail defender, was right on Randle's hip, and when the latter threw up a shot, the freshman jumped up to swat the ball away and leapt clear over Randle before landing on two feet.
Winslow didn't actually get credit for a block on the play, as teammate Quinn Cook was whistled for a foul right before Winslow began his leap, meaning play had been blown dead.
Part of a heralded freshman class for the Blue Devils, Winslow came into the game averaging 15.8 points per game this season. He scored 14 points and had nine rebounds Saturday, helping Duke top the Cardinal 70-59 and remain undefeated at 5-0. Stanford dropped to 3-1.
