Marcus Mariota threw for 198 yards and four touchdowns, including two TD strikes to tight end Colt Lyerla, and No. 2 Oregon beat No. 23 Washington 52-21 Saturday night.

Mariota rebounded from an interception on the Ducks' opening series to complete 15 of 24 passes and host Oregon (6-0, 3-0 Pac-12) won its ninth straight overall dating back to last season, as well as its ninth straight in the series against the rival Huskies (3-2, 1-1).

Lyerla caught three passes for 71 yards, including touchdowns of 10 and 13 yards.

Kenjon Barner, who went into the game ranked 10th in the nation with an average of 121 yards rushing per game, ran for 122 yards and the Ducks built a 35-7 lead at halftime.

Bishop Sankey ran for 104 yards and two touchdowns for Washington.

The two Pacific Northwest teams have a storied rivalry. But because of Oregon's recent domination of the series, the intensity of the rivalry has diminished in recent years. The Ducks' nine-game winning streak is the longest for either side in the series history, which dates back to 1900.

There was little visible contentiousness between the two teams on Saturday night, except for a brief shoving match in the third quarter.

Oregon State 19, Washington State 6: Jordan Poyer had three interceptions, Sean Mannion (Foothill High) passed for 270 yards and No. 14 Oregon State (4-0, 3-0 Pac-12) survived a shaky start with a win over visiting Washington State (2-4, 0-3).

Markus Wheaton had 95 yards receiving and a touchdown but it was the Beavers defense which kept the Cougars at arm's length on the day when Mannion, who threw three interceptions, was more down than up. Mannion completed 25 of 42 passes and was sacked three times.

Louisiana Tech 58, Nevada-Las Vegas 31: Kenneth Dixon rushed for 102 yards and four touchdowns on 16 carries as host Louisiana Tech cruised over Nevada-Las Vegas. The Bulldogs (5-0) matched the 1975 team for the best start in program history. Nick Sherry tossed a pair of touchdowns as UNLV cut the lead to 27-24.

New Mexico 35, Texas St. 14: Kasey Carrier ran for four touchdowns and a career-high 191 yards to lead host New Mexico (3-3) past Texas State (2-3) 35-14. Carrier had TD runs of 37, 1, 19 and 43 yards for the Lobos.

New Mexico completed only one pass on three attempts for nine yards, but the Lobos piled up 361 yards on the ground, the fourth time this season they have gained at least 300 yards rushing. Texas State only managed 32 yards rushing.

Idaho 26, New Mexico State 18: Dominque Blackman threw for 304 yards and two touchdowns, and Idaho (1-5) got its first win of the season in its Western Athletic Conference opener, beating visiting New Mexico State (1-5, 0-2).
