Nina Notman converted a penalty stroke with seven minutes left in the first overtime as No. 2 North Carolina defeated host and seventh-seeded Duke, 2-1, in the first round of the 2014 ACC Field Hockey Championship in Durham.

The win sends North Carolina to the semifinals, where it will take on Syracuse who advanced to the semifinals of the conference tournament with a 5-2 upset over Boston College.

After a scoreless first half, the Blue Devils broke the tie five minutes after the break when Jessica Buttinger fed a pass across the front of goal and found freshman Ashley Kristen on the back post who scored for her fourth of the season.

North Carolina tallied the equalizer in the 46th minute as Samantha Travers fired a shot off a penalty corner, which was deflected in by Emma Bozek for her team-leading 12th goal on the year.

The game winner came after North Carolina’s Emily Wold was awarded a penalty stroke. Notman sent the stroke past Duke goalkeeper Lauren Blazing for her 11th goal of the season and a 2-1 North Carolina victory.

“It’s not easy to beat Duke at Duke, and we knew that coming in,” said North Carolina head coach Karen Shelton. “I’m incredibly proud of our team and of Nina Notman for performing under pressure.”

North Carolina held an 11-9 advantage in shots and had four penalty corners to Duke’s two.

With the win, the Tar Heels move to 43-13 all-time in ACC Tournament play and 3-0 in overtime this season.
