Gamecocks’ Zia Cooke and Destanni Henderson missed 3 points in the final seconds.
The suspense came just hours after Gamecocks and Huskies won the top two in the Associated Press women’s college basketball poll.
Aliyah Boston had 17 points and 15 rebounds for South Carolina (15-2), which overcame a deficit of seven points in the fourth period.
An Aubrey Griffin tray gave the Huskies a 50-43 lead with just over 8 minutes left, before South Carolina turned up the defense and went for an 11-0 run.
Victaria Saxton’s layup on Nelson-Ododa gave the Gamecocks a 52-50 lead, and the Boston jump extended that to 54-50 with just under 2.5 minutes to play.
But Bueckers hit two straight jumpers to tie the game in 54 with 46 seconds remaining in the regulation.
Henderson missed a falling jump with 4 seconds remaining and the Gamecocks lost three chances to take down a game winner.
South Carolina had its 12-game winning streak broken.
