Smith had easily beaten Christie in the seeding round at the previous CT contest in Western Australia, but this time had a heat he would rather forget.
Cardoso won with a score of 10.47 for his two best waves (6.0, 4.47), Christie was second with 9.0 (4.0, 5.0) and Smith struggled to 6.30 (3.67, 2.63).
The top two advanced to the round of 32, while Smith faces the elimination round involving the 16 surfers who placed third in each of the seeding heats. If Christie can move on from the round of 32, he will move up from his 29th ranking. The top 22 at the end of the 11-contest CT season retain their places for the 2020 tour. Hawaiian John John Florence, who won his seeding round heat, leads the overall standings.
