TUCSON, Ariz. (AP) - Noah Fifita threw for 373 yards and five touchdowns in three quarters, Javin Whatley caught two touchdowns and Arizona rolled to a weather-delayed 48-3 win over Weber State on Saturday night.

Lightning led to a delay of more than two hours, but it did little to slow down Arizona (2-0) against the FCS Wildcats (0-2).

Arizona raced out to a 24-0 first-quarter lead, pushed it to 34-0 by halftime and racked up 556 total yards. Its defense had a second straight dominating game, holding Weber State to 184 total yards while forcing two turnovers, including a 27-yard interception return for a touchdown by Jay'Vion Cole.

Offensive coordinator Seth Doege wanted Arizona to sharpen up its passing game after last week's 40-6 win over Hawaii and Fifita responded with a highly-efficient performance. The third-year starter completed his first 14 passes and finished 17 for 22. Whatley had five catches for 168 yards.

Fifita hit Whatley on a 31-yard TD pass on Arizona's opening drive and found him again on its next play from scrimmage for an 85-yard score. Fifita found Tre Spivey on a 10-yard touchdown late in the first quarter and added a 13-yard scoring pass to Brandon Phelps in the second.

Ismail Mahdi opened the second half by turning a third-and-22 screen pass into a 27-yard touchdown and Cole's pick-6 made it 48-0.

Arizona hosts Kansas State next Friday, September 12 at 6 p.m. MST on Fox.
