Ben Brust scored 17 points and Wisconsin devastated American with a 22-5 run to close the first half in a 75-35 victory Thursday before a friendly crowd in the NCAA tournament.
The second-seeded Badgers (27-7) recovered from a brief first-half rut and seven-point deficit to extinguish the dreams of the15th-seeded Eagles (20-13), champions of the Patriot League.
After Wisconsin was ousted in the first round last year as a fifth seed, Brust made sure his senior season didn't end the same way. He attacked the glass for buckets on back-to-back possessions, ending with a 3-point play with 3:33 left in the first half to give Wisconsin a 23-20 lead.
The rout was on. The Badgers hit 57 percent in the second half.
John Schoof had 11 points for American.
