HISTORIC: Top six teams in college basketball all lose for the first time in NCAA history

For the first time in college basketball history, seven top-10 teams lost on the same day.

On Saturday, No. 1 Gonzaga, No. 2 Arizona, No. 3 Auburn, No. 4 Purdue, No. 5 Kansas, No. 6 Kentucky and No. 9 Texas Tech all lost, surpassing the previous record of six top-10 teams in the Associated Press poll losing in one day. Saturday was also the first time the top six teams in the top-25 poll all lost on the same day, according to ESPN Stats & Information research.

The last time six top-10 squads fell in one day was on Feb. 4, 2017. It had happened five times overall.

Gonzaga suffered a 67-57 loss at rival Saint Mary’s. Arizona suffered a 16-point licking by Colorado, the worst defeat by a No. 2 team in the AP poll against an unranked opponent since UMBC upset then-No. 1 Virginia in the opening round of the 2018 NCAA tournament, according to ESPN Stats & Information research.Auburn finished 5-for-24 from the 3-point line in a 67-62 setback at Tennessee. Tyson Walker hit a game-winning 3-pointer with 1.4 seconds to play in Michigan State’s win over Purdue, which followed the Spartans’ 1-5 stretch in its previous six games. Kansas suffered an 80-70 defeat at Baylor. Arkansas outlasted Kentucky in a 75-73 win in Fayetteville. And Texas Tech was edged 69-66 at TCU.

Purdue’s loss to Michigan State could mean that the Boilermakers, who no longer control the Big Ten title race, will end up in a fight to preserve a top-two seed. They’re currently listed as the final No. 2 seed in Joe Lunardi’s Bracketology, while Auburn — 3-3 in its past six games — moved off the top-seed line after the loss to the Vols.

Baylor moved up to the top line, and Gonzaga, Arizona and Kansas preserved their top seeds, despite their defeats, per Lunardi’s bracket.
