Jacy Sheldon sank a floater with 1.8 seconds left to play as third-seeded Ohio State escaped an upset bid from sixth-seeded North Carolina, winning 71-69 on Monday in the second round of the NCAA Tournament in Columbus, Ohio.

Sheldon's shot was in response to a game-tying layup from Deja Kelly with 9.7 seconds left to play. The Buckeyes (27-7) led by as many as 12 points in the fourth quarter but needed the heroics from Sheldon to put away the Tar Heels (22-11).

Sheldon finished with 16 points, six rebounds and five assists, and teammate Taylor Mikesell scored 17 points. Kelly led North Carolina with 22 points and three steals, while Alyssa Ustby and Kennedy Todd-Williams each scored 16 points.

"You know, I told them in the locker room, sometimes it's about X's and O's and sometimes it's about having the best player on the court," Buckeyes coach Kevin McGuff said of Sheldon's game-winner.

Added Tar Heels coach Courtney Banghart: "It's the beauty of March and it's the brutality of March."

Ohio State advances to the Sweet 16 for the second straight season. The Buckeyes will oppose either No. 7 Baylor and No. 2 UConn in a Seattle 3 Regional semifinal.
