USC's win over Drake on Saturday afternoon left us three-fourths of the way through the first round of the 2021 NCAA men's basketball tournament.
And it left Yahoo Tourney Pick 'Em with one perfect bracket remaining.
A Yahoo user named "Tiffany," with a bracket entitled "TCC," is 24-for-24 entering Saturday night.
Another user named "Eli" fell by the wayside with Drake's loss.
Tiffany's perfect bracket
Oral Roberts' upset of second-seeded Ohio State on Friday left 99.7% of Yahoo brackets broken. But not Tiffany's. Tiffany picked Oral Roberts, and North Texas over Purdue, and Oregon State over Tennessee.
When will the perfect bracket get broken?
It remains exceedingly unlikely, however, that Tiffany's bracket will last through the rest of the first round. Think a probability of 2%, or thereabouts.
UConn could break it. Ohio could break it. Oklahoma could break it. BYU could break it. And if none of them do, Tiffany needs No. 14 seed Abilene Christian to stun No. 3 seed Texas.
Tiffany's picks for the remainder of the night:
No. 2 Iowa over No. 15 Grand Canyon
No. 10 Maryland over No. 7 UConn
No. 4 Virginia over No. 13 Ohio
No. 9 Missouri over No. 8 Oklahoma
No. 1 Gonzaga over No. 16 Norfolk State
No. 11 UCLA over No. 6 BYU
No. 14 Abilene Christian over No. 3 Texas
No. 7 Oregon over No. 10 VCU
