Anthony Davis and the top-ranked team in total defense came to Columbus on Oct. 9, 2004, and broke Ohio State's 18-game home winning streak.
Visiting Wisconsin erased an early 10-0 deficit and defeated the Buckeyes, 24-13, at Ohio Stadium.
Davis rushed for 168 yards on 39 carries and scored a second-quarter touchdown to lead Wisconsin's offensive attack. A dazzling 65-yard punt return for a touchdown by Ted Ginn Jr. and a 42-yard field goal by Mike Nugent gave the Buckeyes a second-quarter lead, but the Badgers battled back and held Ohio State's offense at bay in front of 105,090 fans.
"It's absolutely devastating, demoralizing," said redshirt sophomore Jay Richardson following Ohio State's second Big Ten loss in as many games. "This is our stadium. We haven't been beaten here since I've been here. Since my freshman year of 2002 I've never lost here."
Ginn got the crowd on its feet in one of the Ohio State's only highlights. The speedy freshman took UW punter Ken DeBauche's 49-yard kick at the OSU 35-yard line and quickly eluded four Badgers as he broke into the open field for a score.
The touchdown would be OSU's only time reaching the end zone. Quarterback Justin Zwick completed only 15 of 31 passes for 125 yards, and no Buckeye rusher ran for more than 48 yards. Roy Hall was OSU's top receiver, and he only caught five passes for 25 yards.
"We really didn't get anything going, never really got into a rhythm," Zwick said. "Some things worked and some things didn't. We just didn't execute the way we needed to."
The Badgers led 14-13 at halftime behind a 31-yard touchdown run by Davis and an 8-yard touchdown reception by Darrin Charles from quarterback John Stocco. Nugent added a 55-yard field goal as time expired in the first half, but the one-point deficit was as close as the Buckeyes would get.
Wisconsin built its lead with a 26-yard field goal by Mike Allen in the third quarter and a diving 10-yard touchdown catch by Jonathan Orr early in the fourth quarter.
The loss dropped Ohio State to 3-2 on the season and 0-2 in the Big Ten after losing to Wisconsin and at Northwestern a week earlier.
"I guess this puts us at a crossroads," Nugent said. "To be honest, I don't think we're a bad team. The one thing I see is how much work we put into this thing. Then when things don't go our way, it's very frustrating.
"But we have to go back, see what we did that was wrong and try to correct it. The season isn't over – not by a long shot. But we have to play better. I don't think there's any question about that."
Linebacker A.J. Hawk led the OSU defense with 20 total tackles, eight solo stops. Donte Whitner added 17, and Nate Salley had 12. Nugent's two field goals moved him pas Dan Stultz (1997-2000) to become Ohio State's all-time leading field goal kicker.
