Shanghai - The World Aquatics Championships began in earnest for South Africa on Sunday morning, with the first heats of the swimming competition.
There were seven South Africans in action, of whom only Roland Schoeman and Cameron van der Burgh qualified for the evening races.
Schoeman finished 10th fastest in the 50 butterfly in a time of 23.64, 0.38 seconds behind fastest qualifier Cesar Cielo.
Van der Burgh was also 10th fastest in his race, the 100 breaststroke. His time of 1:00.39 was 0.68 seconds off that of Norway's Alexander Dale Oen, who qualified in top spot.
Vanessa Mohr missed qualification for the 100 butterfly semi-finals by just one spot, while Katheryn Meaklim was two places and just 0.18 seconds off semi-final qualification in the 200 IM.
Others failing to progress further were Neil Versfeld (34th in the 100 breaststroke), Heerden Herman (16th in the 400 freestyle), and Wendy Trott (18th in the 400 freestyle).
There was good news in the men's 4x100 freestyle relay, however.
The South African team of Graeme Moore, Darian Townsend, Gideon Louw and Leith Shankland posted a time of 3:14.72 to qualify in seventh spot.
Schoeman will be swimming in the first semi-final, scheduled for 12:38pm, and Van der Burgh's semi-final is set to start at 1:06pm (SA, CAT, GMT+2).
The men's 4x100 freestyle relay final is the last event of the evening session, at 1:36pm.
