LOS ANGELES—The final buzzer sounded and the party was on at Pauley Pavilion.
Jaime Jaquez Jr. rushed into the student section, his shaggy damp hair stuck to his face, and started bobbing up and down. He and his teammates celebrated with the fans after No. 4 UCLA beat eighth-ranked Arizona 81–73 on Saturday night to complete a 17–0 record at home in the teams’ regular-season finale.
