DURHAM, North Carolina (Ticker) -- Shelden Williams never gave North Carolina-Greensboro a chance for an upset.
Williams scored 15 of his 16 points in the first half as No. 10 Duke dominated in every facet of the game and coasted to a 98-44 rout of NC-Greensboro.
The Blue Devils (3-0) never trailed, although the Spartans (2-1) did cut the deficit to 7-6 after a dunk by Ronnie Burrell 3 1/2 minutes into the contest.
That was when Duke took over as Williams scored eight points in just over a minute and Daniel Ewing made two consecutive 3-pointers in a 14-0 run that gave the Blue Devils a 21-6 lead with 13:03 left.
Williams also grabbed 11 rebounds to record his second double-double of the season and 20th of his career - the most among active players in the Atlantic Coast Conference.
The Blue Devils bounced back from a shaky performance against Davidson on Wednesday in which they shot just 38 percent. They shot 62 percent (24-of-39) in the first half against NC-Greensboro while holding the Spartans to 36 percent (10-of-28).
"We kind of refocused," Ewing said. "We played good defense and our offense was a lot better in execution. We shot a better percentage and we were able to get the ball inside-out."
Duke, which led, 60-21, after 20 minutes, pushed the lead to as many as 56 in the second half and played its reserves for the final eight minutes.
Ewing and J.J. Redick also scored 16 apiece for the Blue Devils, who improved to 70-11 vs. North Carolina teams since the 1996-97 season. None of those losses have come to a team outside the ACC.
Duke has won 80 of its last 81 games against unranked non-conference opponents at home.
"Obviously, they're a young team that hadn't played our level of competion," Duke coack Mike Krzyzewski said. "I think that knocked them back."
Kyle Hines scored nine points for NC-Greensboro, which was denied its first 3-0 start in 23 years.
The game was the final tune-up for Duke before hosting No. 9 Michigan State on Tuesday in the ACC/Big Ten Challenge.
"Nobody got hurt," Krzyzewski said. "We played with energy and played hard to start off this week. It's a big week for us."
