Nijel Pack and Miami hit shots from near and far against the stingiest defense in the country to beat Houston 89-75 on Friday night in the Sweet 16, leaving the NCAA Tournament without a single No. 1 seed among its final eight teams for the first time since seeding began in 1979. Miami (28-7), only the fifth team this season to score at least 70 points against Houston (33-4), will play second-seeded Texas or No. 3 seed Xavier in the Midwest Region final for the chance to go to the Final Four. About 30 minutes before Houston's loss, top overall seed San Diego State fell to Alabama in Louisville, Kentucky.
