BERKELEY - It was all working for Cal on Saturday night against Duke at Memorial Stadium. Freshman quarterback Jaron-Keawe Sagapolutele led the Bears on lengthy drives for touchdowns on their first three possessions, producing a 21-7 lead barely two minutes into the second quarter. But the Blue Devils, making their first visit to Berkeley since 1963 when Craig Morton was a junior quarterback for the Bears, scored the final 24 points of the second quarter on the way to a 45-21 victory.
