Whenever North Carolina takes on Duke in any competition, it is considered a bitter rivalry.
In the case of men's and women's swimming and diving, UNC clearly came out on top.
The Tar Heels coolly cruised to a dominating 213 to 84 win for the men, and a 199 to 94 win for the women Tuesday night against their arch rivals at Koury Natatorium.
The victory was the 68th straight on the men's side against the Blue Devils and the 31st straight on the women's side.
Part of the reason for the Tar Heels domination is the fact that Duke is limited with no swimming and diving scholarships, while UNC can offer athletic scholarships to top swimmers.
With the victories, both the men and women's teams improved to 3-1 overall and 2-0 in the ACC. The Duke men fell to 1-4 and 0-3 in the conference, and the women dropped to 2-3 and 0-3.
UNC's men placed first in 14 of 16 events, while the women placed first in 11 of 16.
Several top swimmers did not compete for UNC, as Coach Frank Comfort decided to give younger swimmers the opportunity to compete.
Freshmen Lindsey Marck, a heralded women's butterfly swimmer, had the chance to compete in events outside of her norm.
