SEATTLE - In five previous outings this season, Marcus Mariota was wearing a baseball cap and sending in signals from the Oregon sideline by the time the fourth quarter rolled around.

When the Ducks were finally pushed on Saturday, Mariota and his teammates gave an emphatic response that added another notch to a decade of dominance over their rivals to the north.

Mariota threw for 366 yards and three touchdowns, added another 88 yards and one TD rushing, and the second-ranked Ducks beat No. 16 Washington 45-24 to extend their winning streak in the series to 10.

“Guys were able to battle. I definitely think we’re a four-quarter-type team, we just haven’t had a reason to play four quarters,” Oregon running back Byron Marshall said. “So the fact we got the first one under our belt to answer everyone’s questions is good.”

While Mariota’s passing was nearly spotless, he used his legs to make the Huskies pay when throwing options were covered and he was easily the best player on the field. Mariota completed 24 of 31 passes, and ran another 13times. He threw touchdowns of 4 and 3 yards to Bralon Addison and a 65-yarder to Josh Huff on Oregon’s first possession of the second half. Huff had to be carted to the locker room with an apparent right leg injury in the first half, only to come back after halftime and burn the Huskies secondary.

Most impressive, Mariota answered every challengeWashington made. Twice in the second half the Huskies pulled within a touchdown. Both times, Mariota responded by leading the Ducks (6-0, 3-0) to touchdowns of their own. Mariota topped 300 yards passing for the sixth time in his college career.

“He was awesome. I haven’t seen the stats but he played really well,” Oregon Coach Mark Helfrich said.“He played really smart and very productive. A bunch of guys made a bunch of plays for him too.”

Bishop Sankey ran for 167 yards and touchdowns of 60 and 25 yards for Washington (4-2, 1-2).

MOUNTAIN WEST Boise St. decks Utah St.

LOGAN, Utah - Joe Southwick passed for a career high 335 yards and two touchdowns on 30-of-44 passing as Boise State topped Utah State 34-23 Saturday night.

Shane Williams-Rhodes caught 13 of Southwick’s passes for 150 yards and a touchdown while running back Jay Ajayi added 109 yards and a touchdown on 22 carries for the Broncos (4-2, 2-1 Mountain West).

Junior Craig Harrison made his first start at quarterback for Utah State (3-4, 2-1) after Chuckie Keeton suffered a season-ending knee injury against BYU last week. Harrison went 7 of 17 for 105 yards and rushed for 36 yards.

In other Mountain West Conference games, David Fales connected with Tyler Winston on a 62-yard touchdown catch and run with 5:36 to play to lift San Jose State (3-3, 2-1) to a 34-27 victory over Colorado State (2-4, 0-1) in Fort Collins, Colo. ... Brett Smith ran for two touchdowns, both in the fourth quarter, and passed for another to lead Wyoming (4-2, 2-0) to a 38-31 victory over New Mexico (2-4, 0-2) in Laramie, Wyo.
