Jon Sundvold scored 17 points and Missouri capitalized on an eight-minute, second-half scoring drought by North Carolina State to defeat the ACC team yesterday, 49-42, in a match of top-20 basketball teams at Columbia, Mo.

Steve Stipanovich and Ron Jones provided 10 points apiece for the day and Mark Dressler all nine of his in the second half as Missouri improved its record to 10-2, including 7-0 at home. Stipanovich became No. 2 in all-time Missouri scoring with 1,426 points.

N.C. State (7-2) scored eight straight points, the final two on a perimeter jump shot by Dereck Whittenburg with 10:30 remaining, to take a 35-31 lead. But the Wolfpack went the next 8:05 without a point, missing seven field goal tries, and Missouri went up, 41-35.

Sundvold and Greg Cavener were strong defensively on State's pair of 16.5-point scorers, Whittenburg and Thurl Bailey. Sundvold held Whittenburg to nine and Cavener limited Bailey to eight. Lorenzo Charles led State with 10 points against the Tigers' tight man-to-man.

"We did what we wanted by not letting Sundvold and Stipanovich dominate the game," said State Coach Jim Valvano. "But the credit has to go to Missouri's defense. They did what they had to to win."
