The Pretoria-based outfit collected crucial points to close in on Pirates following a 5-0 win over AmaZulu on Saturday.
Lebohang Bennet Mokoena scored a brace, while the other goals were struck by Ntokozo Siquba, Siyabonga Mabena and Kutlwano Letlhaku.
Mokoena is in sensational form as the youngster tops the scorers' chart with 16 goals.
The Sundowns' emerging gem is on course to break the competition's record of goals scored in a season. Boitumelo Radiopane holds the record for the most goals scored in a single DStv Diski Challenge (DDC) season, after he netted 25 goals for Orlando Pirates during the 2021/2022 campaign.
With eight games remaining, Mokoena can surpass the record that has stood for seasons.
