STANFORD, Calif. (AP) — Bryce Love rushed for a career-high 263 yards and a touchdown to pad his conference-leading total, third-string quarterback K.J. Costello came off the bench and threw for two touchdowns and ran for another as Stanford beat UCLA 58-34 on Saturday. Cameron Scarlett scored three touchdowns and Jet Toner kicked three field goals to help the Cardinal (1-1 Pac-12, 2-2) win their 10th straight over the Bruins after losing starting quarterback Keller Chryst to an injury in the first quarter. Ryan Burns replaced Chryst for one series and made two other brief appearances but it was Costello who directed Stanford's offense most of the night.
