The whistle had apparently not been blown, and the referee then did blow, pointing to the spot. Sirino stepped up and slotted low to the right of Pensy.
Mosimane opted for the pace of Meza for Brockie from the break.
A lapse from Downs soon after the restart – Mosa Lebusa strangely being caught for pace to the run of the awkwardly gangly centre-forward Sall, who turned the Downs centreback to leave him sprawling then finished past Denis Onyango – allowed Leones a goal back.
Sundowns captain Kekana, though, put his team straight back on the front foot, taking a ball from 22 metres onto his less favoured left foot and striking crisply past Pensy to make it 3-0, and 5-1 on aggregate.
Zwane shrugged off centreback Eric Batinga twice on the left to advance and square for Meza, as Downs strolled in their fourth of the night, and the Venezuelan finally his first for his new club.
As Downs continued to flex their muscles Anthony Laffor and Toni Silva followed Meza off the bench.
Sirino’s skill on the left of the area created the space for left-back Lakay to slide in the fifth.
