MADISON, Wis. — A historic day got underway at a parking garage about a block from Ohio State’s team hotel.

The Kohl Center wasn’t available for a morning walkthrough and the Buckeyes were staying in a more contemporary hotel that didn’t feature a ballroom of adequate size to simulate a basketball court. After breakfast, coach Chris Holtmann had his staff scour the surrounding area for a suitable flat surface.

So on a crisp, sunny morning, they found one, walking through the final parts of the game plan in a nearby parking garage. And when they eventually made it to the arena to face Wisconsin, the Buckeyes shattered records and made a little bit of history in an 83-58 win against the Badgers.

Holtmann became the first Ohio State coach to win his Big Ten debut in a game that took place on the road, and he did it with the program’s biggest win at the Kohl Center — an arena where the Buckeyes had been 5-12 and where upperclassmen Jae’Sean Tate, Keita Bates-Diop and Kam Williams had never won.

Wisconsin’s previous biggest loss inside the arena, which opened in 1998, was 17 points.

“I’ve never coached in a game like this,” Holtmann said.

In front of an abnormally subdued crowd of 17,287 that featured nearly a half-dozen empty sections in the upper concourse when the game tipped off, the Buckeyes (6-3, 1-0) never let the Badgers (3-5, 0-1) get into the game. The largest applause of the evening actually came at halftime, when a high-flying acrobat team dazzled during its performance.

Ohio State made its first seven three-pointers as it built a 49-26 halftime lead. After letting double-digit second-half leads evaporate in their previous two games, the Buckeyes instead came out of the locker room and put together a 14-2 run that pushed the lead to a game-high 35 points at 63-28 with 15:31 to play.

The rest was academic.

“For me, I feel like we’ve been here before,” Tate said. “We’ve been up on teams. We can’t get comfortable. That was one thing I said over and over in every timeout: guys, we’ve been here before. Let’s not relax. Let’s just keep on doing the things that got us up until the clock hits zero.”

Freshman center Kaleb Wesson, matched up often with returning All-American Ethan Happ, scored a career-high 19 points in 17 minutes. Happ, who was the focal point of Ohio State’s preparations and faced double-teams each time he touched the ball, was held to seven points on only six shots and turned the ball over four times.

“He’s a great player,” Wesson said of Happ. “I go into every week to prepare against anybody, All-American or not, just go out there and play basketball. But he was a very good basketball player. He played me very hard.”

Ohio State was shooting as well as 75.8 percent before eventually cooling to finish at 66.0 (31 of 47). The last time the Buckeyes shot this well against a Big Ten team was March 6, 2011, when they made 68.1 percent of their shots in a 93-65 home win, also against Wisconsin.

“I think this was as well as we can play for stretches, and we probably caught Wisconsin on a difficult day,” Holtmann said. “To see Jae’Sean and Keita and Kam with a smile on their face, because it’s obviously incredibly difficult to play well here, we feel good about it.”
