Coming off a win in a double-overtime thriller two nights earlier, the Badgers once again found themselves in a game that went down to the wire.
Forward Arnaud Dahi shot 10 of 15 from the floor and grabbed six rebounds to lead the Monarchs with 25 points, in front of his teammate Alex Loughton, who scored 22.
But Badger guard Kammron Taylor, who had game-highs with 27 points and eight rebounds, hit a 3-pointer with 40 seconds remaining in the game to give the Badgers a hard-fought 79-75 lead.
After Badger forward Alando Tucker scored nine points in the first six minutes, ODU went on an 11-1 run and outscored the Badgers most of the game, walking tall with a four-point lead at the half.
The Monarchs simply had too little time to recover from Taylor's 3. Old Dominion's experienced seniors, who finished last year with a school-record 28-win season, had answered Bo Ryan's young badgers throughout the game.
The Monarchs fought hard to get back into the game late, but freshman forward Marcus Landry made 4 of 4 free throws in the final 12 seconds and Taylor connected on 1 of 2 with one second left to close out the Badger win.
"We did well enough to get it taken care of against an experienced team," UW coach Bo Ryan said. "We played two NCAA tournament teams (in this tournament) … and hopefully the guys will learn something from this and gain some experience."
Landry, who had picked up two quick fouls and had to leave the game early, returned and gave the Badgers a boost by scoring seven points and grabbing two offensive boards in two minutes to tie the game 57-57 midway through the second half.
Landry finished the game with 11 points and six rebounds.
Taylor was the Badgers' star guard as he played 34 minutes and only had a single turnover. That lone error was the result of a well-placed pass dropped by forward Alando Tucker, who was coming off a tournament-high 38 points in the Badgers' double-overtime win over Eastern Kentucky Saturday.
"My teammates played unbelievable tonight," said Tucker, who will fly home holding the tournament MVP trophy. Tucker finished the game with 20 points.
