Top-ranked North Carolina, led by the shooting of Sam Perkins and Michael Jordan, defeated The Citadel, 81-36, last night in the opener of the North-South doubleheader in Charlotte, N.C.

In the second game, Thurl Bailey scored 16 points as North Carolina State (11-7), despite making only seven of 30 shots in the first half, beat Furman, 51-48.

If the Tar Heels beat Furman (6-12) tonight--State plays The Citadel (8-10) in the second game--they will give Coach Dean Smith his 13th straight 20-victory season, breaking the NCAA record set by Nevada-Las Vegas Coach Jerry Tarkanian.

Perkins scored 17 points and Jordan 14 as North Carolina (19-3) won its 15th straight.

"They were awesome . . ." Citadel Coach Les Robinson said. "We did not respond to that pressure defense. I was disappointed in the way we played."

The Tar Heels went ahead by scoring six straight points, and their man-to-man defense plaged The Citadel throughout, forcing six turnovers in the first 12 minutes. North Carolina led, 36-21, at halftime.

The Tar Heels began the second half with six straight points on two baskets by Jordan and one by Perkins. Midway through the half, the Tar Heels led, 62-27, and Coach Dean Smith removed his starters for good.

All 11 Tar Heels played, with three scoring in double figures.
