Anu Solomon hit Austin Hill on a 47-yard Hail Mary on the game's final play and Arizona scored 36 points in the fourth quarter to pull off an improbable 49-45 win over California Saturday night.
Cal (2-1, 0-1 Pac-12) threatened to turn Arizona's whiteout into a blowout, deflating the Wildcats and their white-shirt-wearing fans with two quick scores and a 22-point halftime lead.
Arizona (4-0, 1-0) charged back behind Solomon, who threw for 520 yards and had four of his five touchdown passes in the fourth quarter.
The Wildcats recovered an onside kick after Cal was called for a batting penalty and pulled within 2 after Solomon hit Cayleb Jones on a 15-yard scoring pass.
Arizona got the ball back with less than a minute left and pulled off the miracle when Hill brought the ball down between five Cal defenders.
