Ruswahl Samaai, ranked second behind his compatriot in the 2017 global list, took second place with a leap of 8.34m.
Former African champion Zarck Visser settled for sixth place with a 7.88m effort.
While Antonio Alkana was well outside the SA 110m hurdles record of 13.11, he clocked in Prague six days earlier, he won a tight battle in 13.47, just 0.02 ahead of French athlete Aurel Manga.
Sprinter Anaso Jobodwana finished second in the men's 200m sprint in 20.62, taking 0.07 off his season's best, and Carina Horn was third in the women's 100m race in 11.35.

Viljoen won with a best heave of 62.18m, more than three metres ahead of her nearest challenge, as the Olympic silver medallist opened her European campaign with a solid performance.
Erasmus took the men's 100m dash in 10.35, edging out Zambian teenager Sydney Siame by 0.04, while Mokoena delivered a best effort of 7.86m to win the single-leap discipline 27cm clear of his nearest opponent.
