The goal was scored in the first half by Brent Carelse.
The match was entertaining with both sides having scoring opportunities.
Sundowns looked the better side during the first half but in the second half Pirates really took the game to Sundowns and had it not been for a solid defence marshalled by ‘man of the match’ Mbulelo Mabizela including a number of good saved from keeper Brian Baloyi then Pirates would have probably equalised.
