Surfing-Australia's Ewing, Brazil's Weston-Webb win in South Africa

Australian surfer Ethan Ewing won his first World Championship Tour event on Friday, taking out countryman Jack Robinson in the final of South Africa's Corona Open J-Bay in pumping waves at the famed right-hand point break.

Brazil's Tatiana Weston-Webb, who finished runner up in the world last year, powered her way to a win over Australia's two-time world champion Tyler Wright in the women's final with a gutsy performance on her backhand.
