INDIANAPOLIS — For 80 years, Indiana waited. For 36 years, they couldn't beat Ohio State. For 58 years, they couldn't win a Big Ten title outright.

On Saturday night at Lucas Oil Stadium, all of that ended.

No. 2 Indiana stunned No. 1 Ohio State 13-10 in a defensive slugfest to capture the program's first Big Ten Championship since 1945 and first victory over the Buckeyes since Oct. 8, 1988. The win likely guarantees the Hoosiers the No. 1 overall seed in the College Football Playoff and a first-round bye.

The victory caps the greatest season in Indiana football history. The Hoosiers finished the regular season 13-0, becoming just the second undefeated team in program history and the first since Bo McMillin's 1945 squad went 9-0-1.

How It Happened

This was a defensive battle from the opening whistle, and Indiana's unit rose to the occasion against the nation's most efficient offense.

The Hoosiers held Ohio State to just 58 rushing yards on 26 attempts — well below their season average of 81.7 yards allowed per game. Julian Sayin, who entered the game leading the nation with a 78.9% completion rate, was held to 21-of-29 passing for 258 yards with one touchdown and one interception.

Linebacker Isaiah Jones led the charge with two sacks, while Rolijah Hardy tallied a team-high 10 tackles.

Ohio State jumped out to a 7-3 lead after the first quarter, and the Buckeyes took a 10-6 advantage into halftime. But Indiana's defense clamped down in the second half, holding the Buckeyes scoreless over the final two quarters.

The Hoosiers took the lead for good in the third quarter on a Mendoza touchdown pass to Elijah Sarratt.

The Turning Point

With 2:48 remaining and the Buckeyes trailing by three, Ohio State lined up for a field goal to tie the game.

The kick sailed wide left.

Indiana took over with a chance to run out the clock, but faced a critical third-and-6. Mendoza, who had struggled at times in the red zone, delivered when it mattered most — a 33-yard strike to Charlie Becker that moved the chains and allowed the Hoosiers to run the clock and punt it back to OSU with 17 seconds left in the game.

Game over. Indiana wins.

Becker Steps Up

The Hoosiers lost star receiver Omar Cooper Jr. to a leg injury early in the first quarter. Cooper, who entered the game with 58 catches for 804 yards and 11 touchdowns, did not return.

Enter Charlie Becker.

The 6-foot-4 sophomore from Nashville, Tennessee, finished with six receptions for 126 yards — a 21.0-yard average — including a 51-yard catch. His clutch third-down grab in the final minutes will be remembered as one of the biggest plays in program history.

By The Numbers

Indiana outgained Ohio State 340-322 in total yards, with the Hoosiers' ground game proving just effective enough. Kaelon Black carried 16 times for 69 yards, including a long run of 37 yards. Roman Hemby added 52 yards on 13 carries.

Mendoza finished 15-of-23 for 222 yards, one touchdown, and one interception. It wasn't his flashiest performance, but it was enough to earn him Big Ten Championship Game MVP honors.

Jeremiah Smith, the Buckeyes' star sophomore receiver, hauled in eight catches for 144 yards but was kept out of the end zone. Carnell Tate hauled in Ohio State's lone offensive touchdown from Sayin.

What It Means for the Hoosiers

Indiana is Big Ten champion for the first time since 1945, when Harry Truman was in the White House and World War II had just ended. The Hoosiers hadn't beaten Ohio State since Ronald Reagan was president.

The win likely secures Indiana the No. 1 overall seed in the 12-team College Football Playoff, which would give the Hoosiers a first-round bye and home-field advantage in the quarterfinals. The official bracket will be revealed at noon ET on Sunday, Dec. 7.

For a program that went 3-24 in Big Ten play from 2021-23, the turnaround under Cignetti has been nothing short of remarkable. The Hoosiers are now 25-2 in his two seasons at the helm.

What's Next: The College Football Playoffs

The College Football Playoff kicks off with first-round games on Dec. 20-21, but Indiana will be watching from home if they secure a top-four seed as expected. The quarterfinals are set for Dec. 31 and Jan. 1, with semifinals on Jan. 9-10. The National Championship Game is scheduled for Monday, Jan. 20, 2026, in Miami Gardens, Florida.

Cignetti isn't letting his team get comfortable.

"I've got three weeks to get this team humble and hungry for the playoffs," he said. "It only counts if you finish."

For now, the Hoosiers can celebrate. Eighty years is a long time to wait.

Indiana is back.
