Preview: Las Vegas Sevens
However, this landmark will only be special if they manage to clinch another title, Du Preez said. He was part of all three Blitzboks squads that have won titles in Las Vegas since the USA leg of the World Series moved there in 2010.
"I have tasted success here and it's a good feeling. In a way, it is nice to play my 50th tournament here, because Las Vegas has been good to me in the past," he said.
Du Preez paid tribute to all those who helped him along the way to become only the fourth South African player to play 50 tournaments, following in the footsteps of Frankie Horne (68), Kyle Brown (57) and Chris Dry (56).
"I am sure there were a couple of people who did not expect me to get to this mark, but here I am. This was due to hard work, but first and foremost it was because of my parents, who always had my back.
