NCAA Basketball Tournament 2011: Butler Upsets Pitt, One One-Seed Down

Read More: Gilbert Brown (F - Pittsburgh), Matt Howard (F - Butler), Nasir Robinson (F - Pittsburgh), Pittsburgh Panthers, Butler Bulldogs

A No. 1 seed is out of the NCAA Tournament and upset fever has finally hit March Madness, with No. 8 Butler stunning the Pitt Panthers by a score of 71-70. A last-second free throw after a strange set of fouls sealed the deal, with Shelvin Mack's 30 point performance carrying Butler to its seventh postseason win in eight tries, and the possibility of another wild run through the NCAA Tournament waiting for them at the Sweet 16. 

Pitt, 28-6, continues a string of tough upsets for the Big East, which has had a tough time in this year's tournament. Gilbert Brown scored 24 on 8-11 shooting to pace the Panthers, but his missed free throw in the last two seconds of the game led to Nasir Robinson's inexplicable foul and Matt Howard's final free throw. 

Butler will take on No. 4 Wisconsin, who took out Kansas State 70-65, in New Orleans on March 24. The winner of that game will reach the Elite 8, to take on the winner of the BYU/Florida contest held the same day.
