Lorch timed his run to perfection to collect a pass from Luvuyo Memela, before curling the ball into far corner from just inside the box.
The Buccaneers winger scored his first goal of the season and was awarded the Man of the Match accolade.
"First of all I'd like to thank God for the talent he has given me," Lorch told SuperSport after the match.
"We knew it was not going to be easy playing against Platinum Stars especially in their home ground, you know the heat.
"But we planned for the game so I think our plan worked because we got the three points. The goal is from training. I know when "Meme" [Luvuyo Memela] has got to the byline he's going to cut it back. I'd like to wish the chairman a happy birthday."
