Buzz Peterson missed two free throws with one second left yesterday to let No. 4 Southern Methodist escape with an 84-82 victory over fifth-ranked North Carolina in Greensboro, N.C.

North Carolina's Kenny Smith grabbed Peterson's second miss but his follow shot bounded off the rim as the buzzer sounded and spoiled a dramatic comeback by the Tar Heels, who trailed by 11 points in the second half.

"That was a heck of a last play they made," said SMU Coach Dave Bliss. "If the shot falls, it's good. But I guess we were luckier today that we were at Chaminade."

SMU lost to Chaminade on a similar last-second play last month.

Peterson's jumper had cut SMU's lead to 84-82 with 21 seconds left. Ranzino Smith stole the inbounds pass but missed a jumper and Peterson missed a follow.

SMU's Butch Moore was fouled but missed the first of a one-and-one free throw opportunity with 10 seconds left. Peterson was fouled with one second left after rebounding a shot by Martin.

The Tar Heels jumped to a 13-7 lead. But 7-foot Jon Koncak scored 17 of his game-high 31 points in the first half to rally SMU (14-1). SMU led, 36-29, before North Carolina reeled off eight straight points for a 37-36 halftime lead.

Carl Wright had 18 points SMU. Smith and Steve Hale paced North Carolina (12-2) with 18 each.
