PULLMAN, Wash. -- Luke Falk threw for 478 yards and five touchdowns, and No. 18 Washington State rolled to a 45-7 victory over Nevada on Saturday.
Thirteen players caught a pass for the Cougars (4-0). Falk, who was 36 for 47, was replaced by backup Tyler Hilinski in the fourth quarter once a 45-0 lead was built.
Senior running back Jamal Morrow rushed for a game-high 73 yards and also caught four passes for 40 yards and a touchdown.
Nevada (0-4) struggled to move the ball. Blake Wright recorded a team-best 37 yards on five carries while Wyatt Demps caught six passes for 39 yards.
Falk began with four consecutive incomplete passes and a sack, but was able to shake it off and direct the Cougars to a quick lead.
He connected with Tavares Martin Jr. for 52 yards on Washington State's second drive, setting up a 12-yard swing pass to Morrow for a 7-0 advantage. That opened the floodgates on an overmatched Nevada defense, as Washington State scored touchdowns on five consecutive drives.
The Wolf Pack offense faced similar woes. Starting quarterback Kaymen Cureton faced consistent pressure from the front line as he was sacked four times in the first quarter. Nevada managed 15 yards of offense in the opening period.
Nevada switched to quarterback David Cornwell during the second quarter. Cornwell threw for 33 yards in the first half and guided the Wolfpack across midfield for the first time midway through the second quarter.
Nevada's most promising drive of the first half ended like its others, however, as Cornwell was intercepted by safety Jalen Thompson. Falk then maneuvered the Cougars down the field on another scoring drive, ending with a 6-yard touchdown reception by freshman receiver Jamire Calvin.
The Wolf Pack held Washington State to 10 second-half points. Nevada forced two turnovers in the second half, including an interception by defensive back Nephi Sewell at the Washington State 8-yard line.
Two plays later, Cornwell returned the favor with his third interception of the day, to Thompson. The Wolf Pack finally broke through with 1:56 remaining as Maliek Broady ran it in from the 3-yard line.
