Tournament Challenge: 2 perfect brackets

By ESPN.com staff

There are just two perfect brackets left (out of 8.15 million) in Tournament Challenge following victories by Creighton and La Salle on Friday afternoon.

La Salle was the biggest bracket buster, as just 6.1 percent of the brackets picked the 13th-seed Explorers to beat 4-seed Kansas State, knocking down the number from 59 to 2.
