Despite dominating the game and having the lions share of the chances, the Team of Choice failed to get anything out of the encounter even with the Brazilians playing the final twenty minutes a man light - this after Gaston Sirino received two yellows in the space of a 60 seconds.
Emiliano Tade and former United attacker Lebohang Maboe gave the Pretoria side a 2-0 halftime lead, and when Fortune Makaringe pulled a goal back ten minutes from time, it looked like the home side might still steal a point.
But it was not to be as Sundowns held out for the win.
"I feel for the boys because I think they deserve more," coach Eric said. "If I look at all the games that we lost I think we deserved more but you know that does not help us, points helps us.
"That is what the game is about, that's how I get judged as a coach. It's not how pretty the team might be playing and how many chances we created.
"That means very little. What it means is we are still sitting at the bottom of the table and that is the harsh reality.
"You have to give credit where credit is due. The chances they get, the chances the punish and that was the difference here tonight. Quality in front of goal."
The Midlands based club remain in 16th place on 17 points and have six fixtures left in the campaign to save their status and coach Eric remains optimistic about survival.
"There will always be hope," he added. "As long as I am here and also the people at the club believe. They have done it before, funny enough on the exact same points at the time and they avoided relegation."
Tinkler and his team have three weeks to prepare for a visit from Bloemfontein Celtic on April 5. Kick-off is at 20h00 at the Harry Gwala Stadium.
