Guards Kenny Smith and Ranzino Smith scored 16 points apiece to lead a balanced North Carolina offense as the top-ranked Tar Heels routed The Citadel, 104-51, in a college basketball game yesterday in Charlotte, N.C.

The Tar Heels (10-0) led, 12-7, with 13:15 left in the first half before putting together scoring runs of 12-0 and 14-0 to take a 48-16 halftime lead.

Dunks by Brad Daugherty, Curtis Hunter and Warren Martin highlighted the first scoring surge, which gave the Tar Heels a 24-7 lead with 8:31 left in the first half.

Six different players scored in the second run, as the Tar Heels took a 48-14 lead before a final basket by The Citadel.

The Bulldogs (4-3) made good on just 21.2 percent of their shots from the floor in the first half and went without a basket for nearly six minutes midway through the half and again for about four minutes late in the period.

North Carolina, which surpassed 100 points for the fourth time this season, led by as many as 55 points in the second half. The Tar Heels shot 61.1 percent for the game.

North Carolina placed five players in double figures, including Daugherty with 15 points, Steve Hale with 14 and Martin with 13. Daugherty had a game-high 11 rebounds as the Tar Heels outrebounded the Bulldogs, 48-34.

The Citadel was led by Craig Bardo with 10 points. Air Force 56, Army 50

The Falcons, led by Jim Gulsvig's 16 points, defeated the Black Knights in the second game of the Suntory tournament in Tokyo.

Air Force, which dropped the first game of the annual tournament to Navy, 70-53, in Osaka Saturday, now is 6-3. The young Army team, which starts only one senior, is 4-3.

Army junior Kevin Houston was the game's top scorer with 25 points, but his team's starting forwards and center could manage only 10 points among them.

The teams were called for a total of 54 fouls in a rough game.

The Falcons moved in front for good at 9-8 after 6 1/2 minutes of the first half. After five minutes in which neither team could score, Air Force moved out to an 18-11 lead with 5:22 left in the half on six points by Gulsvig and a three-point play by center Mike Lockwood.

Air Force led, 25-18, at halftime and maintained an eight- to 10-point advantage through most of the second half, although Army made it close in the final minutes.

Houston, who hit on only two of eight from the field in the first half, scored 14 of his points in the last 12 minutes, moving the West Point team to within four at 52-48 with 90 seconds to go.

But Gulsvig and Eric Kjome then made two free throws apiece.

The game was watched by 12,236 at the national sumo arena.

Army will meet the Midshipmen, now 5-2, in the final game of the tournament Monday night.

The Suntory tournament is an NCAA-sanctioned event that this year brought the three U.S. military academy teams together for the first time.
