Matsatsantsa dominated the match, but could not convert those chances into a valuable away goal.
SuperSport kept Atletico’s attackers frustrated, setting a lot of offside traps.
Edwin Gyimah had the best chance of the half, when his shot from outside the box just before half-time went over the bar.
In the second half, Prince Hlela’s free-kick found Gyimah, but the Ghananian’s header was straight at the keeper.
On 53 minutes Petro were reduced to 10 men when Miguel was shown a straight red card for a dangerous tackle on Thabo Moloi.
On the hour mark a great through-ball by Ashley Hartog found Thabiso Nkoana but the speedy forward shot straight to the keeper.
And those two players were substituted for Sibusiso Zuma and Kermit Erasmus on 65 minutes.
The subs were straight into the thick of things, as Erasmus had a couple of shots on target, forcing a great save from the goalkeeper late on, before Zuma’s bicycle-kick hit the crossbar.
SuperSport host Atletico in the second leg on the weekend of April 5-7.
SuperSport line-up: Williams, Moloi, Diouf, September, Fransman, Hlela, Gyimah, Mdluli, Hartog, Nkoana, Nyondo
