After breaking a 12-game losing streak to the Tar Heels on Saturday , the Blue Devils shut out UNC 4-0 Sunday to clinch the inaugural Carlyle Cup.
Duke starter Justin Dilucchio and four relievers limited UNC (25-20, 6-12 in the ACC) to six hits while stranding 13 Tar Heels in the shutout performance.
The victory gave Duke (20-25, 7-10) a 2-1 series win and the three decisive points in the all-sports competition between the rival athletic programs.
"I think we knew we were going to win," Dilucchio said. "It is a great rivalry and a great win for us."
UNC starter Daniel Moore didn't make it out of the third inning as the Blue Devils struck for three early runs.
Duke got on the board in the first when Drew Jerdan knocked in shortstop Kevin Kelly with an RBI single.
Senior David Mason got things started in the second with a lead off single to left and Gideon Thompson followed with a bloop double down the right field line.
Mason scored on Adam Loftin's sacrifice fly and some aggressive base running led to Duke's third run of the day.
Moore fanned Scott Grossi for the second out of the inning, but the ball skipped away from catcher Ron Braun who had to throw to first to retire Grossi.
