This was the second meeting between these two sides in five days at Mbombela Stadium, following a 1-1 draw in the Absa Premiership on Wednesday.
This time, however the Brazilians were comfortably the better side.
Modise put Sundowns in front in the 58th minute, curling home a fine free kick that found its way inside Jackson Mabokgwane’s near post.
And former Aces midfielder Zwane sealed the win in the 75th minute, beating Mabokgwane from the edge of the area, following some lovely attacking interplay.
