EUGENE, Ore. (AP) — Marcus Mariota threw for 267 yards and three touchdowns then ran for one more before sitting out the second half, leading the third-ranked Oregon Ducks to a 62-13 victory over South Dakota in the season opener for both teams on Saturday night.

Running back Byron Marshall was Oregon's top receiver with eight catches for 138 yards and two touchdowns for the Ducks, who have won 10 straight home openers. Freshman Royce Freeman, a five-star recruit out of Imperial, California, ran for 75 yards and two more scores.

Mariota's 62-yard touchdown pass to Dwayne Stanford on Oregon's first series of the game gave him the Ducks' career record for touchdowns with 79 (64 pass, 14 rush and one reception), surpassing Joey Harrington.

Trevor Bouma ran for a 3-yard TD and Miles Bergner kicked a pair of field goals for the Missouri Valley's Coyotes, who went 4-8 last season but were surprisingly plucky against the bigger and faster Ducks.
