TAMPA, Fla. - Duke's reign as kingpins of the Atlantic Coast Conference tournament is over.<br>

Freshman Brandon Costner scored a career-high 30 points and Engin Atsur scored all 21 of his points after halftime, helping 10th-seeded North Carolina State defeat the defending tourney champions 85-80 in overtime Thursday night.<br>

No. 21 Duke (22-10) had won seven of the previous eight ACC tournament titles, including the past two, but entered the league's signature event this year as the seventh seed, the Blue Devils' lowest seeding since 1995.<br>

North Carolina State (16-14) avenged a 23-point regular-season loss to Duke and beat its nearby rival for just the third time in the past 23 meetings between the schools. The Wolfpack advanced to Friday's quarterfinals against No. 2 seed Virginia.<br>
