"I think we took care of the ball," Ohio State head coach Jim Foster said. "We executed and we moved the ball well. We scored 88 points so I'm not going to complain. I was encouraged by our defensive intensity. We had a significant defensive practice yesterday and it carried over well today."
All 13 Buckeyes who saw the floor scored at least two points.
Clara Mitchell led the Jaguars (0-5) with eight points.
Former Buckeye All-American Katie Smith will be part of the BTN broadcast team for the Cal game.
