MADISON, Wis. — Ben Brust scored 19 points and No. 4 Wisconsin remained unbeaten with a 75-71 victory over No. 22 Iowa on Sunday night.

Wisconsin (15-0, 2-0 Big Ten) matched the best start in school history, tying the 1911-12 and 1913-14 teams.

The game was physical at times, drawing loud protests from both coaches. But Iowa coach Fran McCaffery boiled over after a foul was called on Gabriel Olaseni that sent Nigel Hayes to the line.

McCaffery was ejected with 12 minutes to play after two technical fouls were called. He continued to confront the officials as his assistants tried to restrain him.

Brust then hit all four free throws off the technical fouls, and Hayes converted one of two on the personal.
