Australia's Ethan Ewing recorded a first World Surf League (WSL) Championship Tour victory at Jeffreys Bay, while Brazilian Tatiana Weston-Webb won the women's contest to move into the top five in the season standings.

Ewing had been among the most consist surfers on the Championship Tour this season, entering the event in South Africa fifth overall with three top-three finishes. 

The 23-year-old defeated home surfers Matthew McGillivray and Jordy Smith en route to the final four, and posted a two-wave score of 17.04 to beat Brazil's Yago Dora by just 0.17 points to earn a place in the final.

Facing compatriot Jack Robinson, Ewing earned scores of 7.67 then 9.13 in the final to claim a landmark victory.

The first of those waves saw Ewing make numerous sharp turns on a long run, before Ewing went airborne on the second and exhibited impressive balance to stay on the board.

Weston-Webb knocked off Costa Rican Brisa Hennessy in the quarter-finals and reigning WSL and Olympic champion Carissa Moore in the semi-finals, after the Hawaiian was slapped with an interference penalty.

Australia's Tyler Wright - making a comeback after COVID-19, injury and visa issues kept her out of three consecutive legs - faced Weston-Webb in the final.

Weston-Webb had no difficulty picking up speed and edged the final 17.50 to 15.67.

Second place still represents a great result for two-time WSL world champion Wright, who has climbed three places in the standings to seventh, two off the cut line for the end-of-season finals.

One leg is left before the finals.

Weston-Webb also climbed three places to third, with American Lakey Peterson - an elimination-round victim - dropping out of the top five.

France's Johanne Defay joined Moore in having cinched a spot in the final five.

On the men's side, Robinson did the same via his second-place finish.

While Ewing has moved up to third, the top five remains unchanged; Brazil's Olympic champion Italo Ferreira and Griffin Colapinto of the United States complete it, with Brazilian Filipe Toledo leading the way.

Kanoa Igarashi from Japan - the Tokyo 2020 silver medallist - reached the semi-finals and has closed the gap, now being 1,275 points off the top five.
