STANFORD, Calif. — Jordan Bell scored on a putback with 14 seconds left to give No. 6 Oregon its second straight nail-biting victory in a rare Bay Area sweep as the Ducks beat Stanford 75-73 on Saturday. Bell’s game-winner followed Dillon Brooks’ last-second, tiebreaking 3-pointer three nights earlier at California to give Oregon (26-4, 15-2 Pac-12) its second sweep of its conference Bay Area rivals since 1976.
