CHARLOTTESVILLE, Va. – RJ Barrett got it started, Zion Williamson filled in some gaps and Cam Reddish added a late flurry.
Those three Duke freshmen — plus one more, point guard Tre Jones of Apple Valley — all had starring roles Saturday night as the No. 2 Blue Devils used an early barrage of three-pointers to stun No. 3 Virginia, and then held off the Cavaliers 81-71 to sweep the season series.
"That really sets the tone for us, and we played defense today as well," Barrett said of the fast start.
Barrett made five three-pointers before the game was 12 minutes old, helping Duke (21-2, 9-1 ACC) quiet a sold-out John Paul Jones Arena.
"We were just in our zone, and it's great to see when our team is like that," Barrett said.
He finished with 26 points, Williamson had 18 and Reddish had 17, including three three-pointers early in the second half. Jones had 13 points, six rebounds, seven assists and two steals.
"It's any given night for all of us," Reddish said after finishing five of eight from beyond the arc. "We all can do a mixture of everything, and it just depends on who gets found, who's open and it's a simple as that."
Duke finished 13-for-21 from three-point range after making just two of 14 in a 72-70 victory against Virginia on Jan. 19.
"It's a little bit deflating when they're banging threes and you're trying to keep them out of the lane," Virginia coach Tony Bennett said.
Bennett thought his team might have overadjusted by focusing too much on trying to close off the inside, but his counterpart, Duke's Mike Krzyzewski, thought it was at least as much a case of his own players recognizing the strategy change.
"My players felt it," Krzyzewski said. "That little bit of room — they took advantage of it without any kind of coaching."
Duke now shares first place with North Carolina and has two games left with the Tar Heels.
Virginia (20-2, 8-2) had won 13 straight at home.
