Down a goal with 10 minutes to go against North Carolina on Thursday night, the Duke women's soccer team needed some momentum.
And Casey McCluskey, the ACC's second leading goal scorer, was just the one to give the team a spark.
The Blue Devils moved the ball into UNC's backfield, and McCluskey broke ahead of the pack. She received a pass with nothing but grass and the goal in front of her.
Just when she thought she was free, the linesman raised his flag, signaling offsides.
McCluskey trotted back with her head down. The play was a typical moment during her frustrating game.
The senior forward has 57 shots on the season but registered none against the Tar Heels' suffocating defense.
McCluskey said she was thrown off by UNC's aggressive tactics, which push more toward the offensive end of the field than most teams'.
"They play a really high restraining line, and they push up really quick," she said. "I, personally, got called offsides like 15 times."
The UNC defense targeted McCluskey all night, effectively taking her out of the game.
