C.J. Stroud threw two touchdown passes and Ohio State shut out No. 5 Notre Dame over the final 42 minutes in a gritty 21-10 victory on Saturday night.

“The story of the night was the defense, to turn around and play the way they did after what’s been said about them in the offseason, questioning their toughness, and play the way they did against the No. 5 team in the country … I thought the energy was off the charts for the defense tonight,” Ohio State coach Ryan Day said.

The Irish managed just 253 yards and punted on their last six possessions. Tommy Eichenberg had two of Ohio State’s three sacks.

“We got a lot to prove. And everyone just played extremely confident, too,” Eichenberg said.

The Irish D could only hold up for so long.

On a third-and-long, Notre Dame brought multiple blitzers and Ohio State gave Stroud plenty of time to find Xavier Johnson open down the vacated deep middle for a 24-yard score. That put the Buckeyes up 14-10 with 17 seconds left in the third quarter.

On its next drive, Ohio State asserted itself. The Buckeyes went 95 yards on 14 plays, killing seven minutes off the clock and making it 21-10 on a 1-yard surge by Miyan Williams.

Williams ran for 84 yards on 14 carries and TreVeyon Henderson had 91 on 15 attempts.

Ohio State led the nation in scoring and yards per play last season, but for much of the night it was a slog for Stroud. And Day seemed thrilled to see his team endure.

“We wanted to be known as something other than talented,” Day said.
