The Wolfpack notched an early goal in Thursday's game at SAS Stadium and went on to defeat the Tar Heels 2-1.
UNC (10-1-2, 0-1 in the ACC) showed more than one moment of weakness as the Wolfpack (8-3-1, 2-0-1) made itself only the fifth team to upset the Tar Heels in 117 ACC games.
Less than two minutes into the match, State found a hole in UNC's defense. Wolfpack forward Adrienne Barnes reacted to ball a deflected off goalkeeper Aly Winget and returned the shot for an unassisted goal.
"The first goal was miscommunication between our goalkeeper and defender," said UNC midfielder Maggie Tomecka. "It was just an unlucky goal."
After State took the early lead, the Tar Heels struggled to regain a sense of composure that had eluded them since before the first whistle. The team arrived late to SAS Stadium due to traffic and bad weather.
And while UNC stood off its usually stately guard, State rose to the occasion. Wolfpack goalkeeper Gretchen Lear tied an ACC record with 19 saves.
Wolfpack coach Laura Kerrigan said she was impressed by Lear's performance, especially after a particularly rough game against Maryland last week.
"For her to come up with this type of performance after being injured almost the whole week was unbelievable to me," Kerrigan said. "She really shows what she's made of."
Coming out of the half, UNC coach Anson Dorrance replaced Winget with veteran Jenni Branam, who has been battling a nagging knee injury all season.
