Texas held Demond Stewart, the nation's top scorer, to a season-low five points Tuesday night and overpowered Niagara, 85-48.
Stewart was averaging 27.1 points, but made only 2 of 10 field-goal attempts before he fouled out with 13:36 left in the second half. He played only 18 minutes.
The Purple Eagles had no answer to 7-foot, 262-pound junior Chris Mihm, one of the better big men in college basketball, and 6-7 Gabe Muoneke, an All-Big 12 forward. They dominated inside in the rout before 7,577 at the Erwin Center.
Mihm went over the 1,000-point mark for his career as he scored 22 and pulled down 14 rebounds. Muoneke had 14 points in just 23 minutes. Coach Rick Barnes' 18th-ranked team is 7-3 with losses to Arizona, Utah and Wisconsin.
Niagara (6-3) held an 11-5 lead after 4:14 but the Longhorns' class soon showed. Texas led, 38-15, before the next NU basket with 1:11 left in the half.
Often forced into wild, off-balance shots by Texas' aggressive defense, Stewart was clearly frustrated. But the rest of the Purple Eagles were only 15 for 45 (33.3 percent). Texas, using a mix of full- and half-court pressure defense, forced 27 turnovers.
"An excellent defensive team, as good as we'll see all year," said Niagara coach Joe Mihalich.
Terry Edwards, who opened the game with a three-point basket, led Niagara with 12 points, seven at the foul line.
Niagara's next game is Sunday afternoon at St. Bonaventure.
