Quarterback K.J. Costello threw for a career-high five touchdowns — the second-most in a game in program history — to go along with 344 yards and one interception in Stanford's 49-42 win over UCLA. JJ Arcega-Whiteside also climbed up the Cardinal record book as he was on the receiving end of three of those scores for 106 yards, moving up to third place in career 100-yard receiving games with eight.
