High Quality Content by WIKIPEDIA articles! The 1999–2000 Premier Soccer League, known as the 1999-2000 Castle Premiership for sponsorship purposes, was the fourth season of the Premier Soccer League since its establishment in 1996. The season began on 30 July 1999 and ended on 4 June 1999. Mamelodi Sundowns once again managed to secure their crown, sealing their third successive PSL title. Along with their success in the PSL`s predecessor - winning three National Soccer League titles in 1988, 1990 and 1993 - this gave Mamelodi Sundowns their 6th South African championship. Sundowns tallied 75 points for the season, equalling the points record they jointly set with Kaizer Chiefs last season, but unlike the previous season in which the title was decided by goal difference, there was no close title race this season as Sundowns finished comfortably ahead of second placed Orlando Pirates with an 11 point margin.
