The Buckeyes have won their first seven games this season by an average margin of 30.6 points.

Wisconsin (2-5, 0-4) has lost its last five games by an average margin of 25.2 points and has dropped its last 10 matchups against Power Four conference teams.

No. 3 Indiana 38, Michigan St. 13: Fernando Mendoza completed 24 of 28 passes for 332 yards and four touchdowns and the Hoosiers celebrated their highest ranking in program history with a home rout of the Spartans.

Indiana (7-0, 4-0) scored touchdowns on its first five possessions.

Mendoza threw a pair of TD passes to Elijah Sarratt, and also hit E.J. Williams Jr. and Omar Cooper Jr. for scores.

Mendoza, a redshirt junior transfer has 21 TD passes and just two interceptions this season.

Michigan State (3-4, 0-4) lost its fourth in a row by double digits. Spartans quarterback Aidan Chiles completed 27 of 33 passes for 243 yards and one TD.

No. 8 Oregon 56, Rutgers 10: Dante Moore passed for 290 yards and four touchdowns and the Ducks followed their first loss of the season with a road romp over the Scarlet Knights in the first meeting between the schools.

A week after falling 30-20 to Indiana at home, Oregon (6-1, 3-1) extended the nation’s longest road winning streak to 10 games.

Noah Whittington ran for 125 yards and two TDs and the Ducks piled up 750 total yards — 415 rushing and 335 passing.

The Scarlet Knights (3-4, 0-4) have not beaten a ranked team in 16 years, the longest active streak in college football. They managed just 202 total yards with quarterback Athan Kaliakmanis constantly under pressure. He was 8 of 25 for 79 yards, threw two interceptions and was sacked three times.

Iowa 25, Penn St. 24: Iowa quarterback Mark Gronowski rushed for 130 yards and two touchdowns, and Kaden Wetjen scored the go-ahead touchdown on an 8-yard run with 3:54 to play, as the Hawkeyes defeated the visiting Nittany Lions.

Iowa (5-2, 3-1) trailed 24-19 with 4:56 to play after Penn State’s Ryan Barker kicked a 32-yard field goal, but Gronowski ran 67 yards on the first play after the ensuing kickoff, setting up Wetjen’s run one play later.

It was the fourth consecutive loss for the Nittany Lions (3-4, 0-4), playing their first game for interim coach Terry Smith six days after the firing of James Franklin.
