However, this victory came at a price for Sundowns as they have lost first choice goalkeeper Denis Onyango with suspected concussion as he departed the stadium in an ambulance and his neck supported by a brace shortly before half time.
Onyango collided with City striker Mbulelo Wagaba and landed awkwardly after they went for an aerial ball and he was replaced by Kennedy Mweene, who is likely to be called again for duty in the MTN8 quarter-final clash against Lamontville Golden Arrows on Saturday at Loftus.
For City coach Jozef Vukusic, it is worrying as they are languishing at the foot of the table with nothing to show for their troubles after they both their opening matches.
Mosimane made four changes to the team that drew with Chiefs with Thapelo Morena coming in for Anele Ngcongca and Motjeka Madisha replacing Wayne Arendse in the defence.
In the midfield, Tiyani Mabunda replaced captain Hlompho Kekana while Maboe, who made his debut as a late substitute against Chiefs, made his first start in the place of Sibusiso Vilakazi in the attacking department.
