LOGAN, Utah (Ticker) -- Joey Harrington threw two touchdown passes and ran for another as sixth-ranked Oregon pulled away and remained unbeaten with a 38-21 road victory over winless Utah State.
Harrington had a 24-yard touchdown pass to fullback Josh Line in the second quarter and a 27-yard TD strike to tight end Justin Peelle in the third. But Oregon (4-0) led by just 24-21 entering the fourth quarter.
The Ducks seemed to weaken Utah State's defense late in the game as Onterrio Smith scored on a four-yard touchdown run with 12 1/2 minutes left for a 10-point bulge. Maurice Morris, who broke through for 175 yards on 22 carries, added a 69-yard touchdown run for the final margin.
The Ducks, playing their first road game of the season, still have contests at Oregon and California in a stretch of three straight games outside Autzen Stadium.
Oregon fashioned five drives of 79 yards or more as Harrington efficiently led the offense. Harrington led fourth-quarter comebacks in two of the Ducks' first three games.
Harrington completed 17-of-24 passes for 261 yards and the two touchdowns.
Smith added 98 yards rushing as Oregon outgained Utah State on the ground, 289-77.
Emmett White, who gained a season-high 274 yards rushing last week for the Aggies against Wyoming, was limited to 83 yards on 23 carries.
Utah State (0-4) scored first on a 32-yard touchdown reception by Kevin Curtis from Jose Fuentes. After Line's touchdown, Harrington capped a 11-play, 89-yard drive with a 1-yard TD plunge and the Ducks took a 17-7 halftime lead on freshman Jared Siegel's 46-yard field goal as time expired.
Forced to throw due to the lack of a running game, Fuentes was 26-for-46 for 356 yards but was intercepted four times, including three times in the fourth. Oregon's Steve Smith had one of the interceptions after recording three in last week's 24-22 triumph over Southern California.
The Aggies' other touchdowns came in the third quarter on a three-yard TD run by White and an eight-yard TD strike from Fuentes to Gary Coleman. The second score pulled Utah State within three points for the final time before Harrington patiently led the Ducks to the two fourth-quarter scores.
The Ducks outgained the Aggies, 550-455 but were penalized eight times for 80 yards.
