Dolly set up Thamsanqa Gabuza for a brace before adding two brilliant long-range strikes with his left foot in their 4-0 demolition job of Gambia on Saturday.
The win means that South Africa have six log points and could book a spot in Gabon next year as one on the best second-placed teams if they beat Mauritania in September.
The 23-year-old former Ajax Cape Town man was in inspired form, taking on the Gambians from his left wing.
It was a great way for Dolly to kick off his international career after a season of constant improvement and success with Downs.
Dolly was pleased, saying: “This has been some year for me. I have won lots of things, selected for major awards and now being called for the national team and do this.
“It gives me a wonderful feeling but I want to continue working hard so that I repay the faith my coaches have placed on me.
“I want to thank my teammates, coach Mashaba and his staff.
“My career is really blossoming but will continue to work hard, keep my feet grounded and put more effort in whatever I do.
“The coach told me to shoot when I am within range and I did exactly that in the second half and the rest as they say, is history.
“With the team leading 2-0 and cruising, I told myself ‘give it a go’ and boy I have never felt so good. But more is still to come, watch this space.”
Bafana coach Shakes Mashaba says the win was one of the best performances ever by the senior national team.
Bra Shakes says: “That was total football from the boys and it only goes to show the amount of potential we have in the country. Winning by such a massive margin and away from home shows this team can go places.
“Can this be one of the best Bafana Bafana teams ever? I think the team that played Gambia can really go places and achieve lots of things going forward...”
