DURHAM - North Carolina's Richard Treis believes playing the last 18 holes of golf is easier than the first. His teammates would have to agree. The Tar Heels shot eight strokes lower than their first effort with a 293 team score in the second round. However, the late surge was just good enough to place UNC in seventh place out of 18 teams in the 2000 Iron Duke Golf Classic with an overall score of 593. The final round of competition will begin Monday morning. "As a team, we definitely improved after the first 18 holes," Treis said.
