CHAPEL HILL, N.C. (AP) -- Tyler Zeller had 19 points and 13 rebounds to help fifth-ranked North Carolina beat Elon 100-62 on Thursday night.
Harrison Barnes added 18 points for the Tar Heels (12-2), who blew the game open with a dominating 23-0 run midway through the first half. North Carolina led 53-19 by halftime then pushed the margin to as many as 50 points after the break.
North Carolina won its 25th straight game in the Smith Center to tie the record for its longest winning streak in the nearly 26-year-old campus arena. That home winning streak is tied for third-longest in program history.
Sebastian Koch scored 17 points for the Phoenix (7-5), who lost their third straight game and remained winless against ranked opponents since entering Division I competition a dozen years ago. Elon shot just 33 percent, including 7 for 28 from 3-point range.
