The fourth day of March Madness narrowed down what on Thursday was a field of 64 to just 16 contenders. While there weren't as many major upsets as Saturday, a third double-digit-seeded team advanced to next week's games -- and any Ivy League team made the Sweet 16 for the first time in more than 30 years.
Ohio State topped 10-seed Georgia Tech, 75-66.
12-seed Cornell handily beat a higher-seeded opponent for the second time in three days. They are the first Ivy League team to crack the Sweet 16 since 1979.
Michigan State stunned Maryland at the buzzer, winning 85-83 in a game with an absolutely thrilling ending.
2-seed West Virginia sent Missouri packing, 68-59.
6-seed Xavier narrowly edged Pittsburgh, a 3-seed, 71-68.
1-seed Duke, a team that fans love to hate, handily defeated Cal, 68-53.
It took an overtime to determine a winner, but Purdue outlasted Texas A&M in Spokane to become the final Sweet 16 member.
