ATHENS, Ga. (AP) _ Leaonna Odom scored a career-high 25 points, including nine in Duke's dominant third period, and the fifth-seeded Blue Devils beat No. 12 seed Belmont 72-58 in the first round of the women's NCAA Tournament on Saturday.

Duke (23-8) led only 32-31 at halftime before outscoring Belmont 21-9 in the third period.

Kylie Smith led Belmont with 20 points. 

Duke's Rebecca Greenwell, who had 18 points, opened the third period with a layup and closed the quarter by sinking a 3-pointer to give Duke a 53-40 lead.  

Belmont (31-4) saw its 22-game winning streak end. The Bruins were denied in their bid for their first NCAA win.

Belmont scored the first six points of the final period, closing the gap to 53-46, forcing a timeout by Duke coach Joanne P. McCallie. Odom ended the run by scoring on a layup and a jumper following the timeout.
