Jordan Wolf's goal at the 2:34 mark of the first overtime period lifted host No. 6 Duke to a 9-8 win over No. 7 North Carolina on Saturday at Koskinen Stadium.
"Christian Walsh came down and made a nice move," Wolf said. "We've been playing together for a long time and have great chemistry, and I knew he was going to throw it to me and set a pick. I attacked the ball, got to five-on-five, inside roll and stuck it, fortunately."
The Blue Devils improved to 6-2 overall and 1-1 in the Atlantic Coast Conference while the Tar Heels fell to 5-2, 0-2.
"I just thought it was everything that is good about our sport," coach John Danowski said. "I thought it was a great display for college lacrosse."
Trailing 8-7 with less than two minutes left in the game, Duke scored the equalizer when Kyle Keenan used a roll dodge on the right-hand side for his career-high third goal of the day at the 1:47 mark.
The Blue Devils later had possession for the final 45 seconds of regulation, but the Tar Heels defense denied a shot attempt.
