LOGAN, Utah -- Darrell Garretson passed for 370 yards and three touchdowns on 28-of-41 passing to lead Utah State past Hawaii 47-10 Saturday.
Joey DeMartino ran for 104 yards and a touchdown for USU (5-4, 4-1 Mountain West), his fourth career 100-yard-plus game. Hawaii (0-8, 0-0) starting quarterback Sean Schroeder passed for 213 yards and one touchdown but was intercepted three times.
Garretson's TD passes went to three different receivers, including scores in the second half by Travis Reynolds (30 yards) and Wyatt Houston (44 yards). Hawaii's lone touchdown came on a 33-yard pass from Schroeder to Keith Kirkwood on the first series of the third quarter.
The Rainbow Warriors missed on another scoring opportunity in the third quarter when Tavita Woodard intercepted a Garretson pass at the 30 and returned it inside the USU 10. Two plays later, Aggie linebacker Kyler Fackrell intercepted a short pass by Schroeder and ran 99 yards for a touchdown.
Freshman Garretson started his second game for Utah State, filling in when Chuckie Keeton went down with a season-ending knee injury in a game against Brigham Young. Garretson became the first freshman to pass for more than 300 yards for USU since 1985. He was replaced by Craig Harrison with 9:24 to play in the game.
USU scored twice in the first quarter, beginning with an 11-yard pass to Bruce Natson with 14:27 to play and Nick Diaz kicked a 40-yard field goal. DeMartino ran for a 4-yard score on the second play of the second quarter, while Diaz added a 33-yard field goal after USU stopped a fake punt by Hawaii at midfield.
With 50 seconds left in the half, USU added a 52-yard field goal by Jake Thompson, his first career attempt.
