Maseko fired into the bottom corner in the 63rd minute to ​put South Africa, who will face co-hosts Canada in Los Angeles on June ⁠28, on four points behind Group A winners Mexico, who beat the Czech Republic ​3-0.

South Korea, who started with talisman Son Heung-min on the bench, have three points.

South Africa had failed to advance ​from the group stage in their first three World Cup appearances in 1998, 2002 and 2010.

“It was a fantastic experience. It was so tough today, but it was a good game. I think tactically we were ​very good and it was difficult for South Korea to find space,” South Africa coach ​Hugo Broos said.

“We scored, then there were 20 minutes of heart-stopping moments. It’s historical, and I’m very happy ‌for ⁠the guys. I’ve been working with them for five years.”

South Korea, who enjoyed most of the possession but lacked a cutting edge and inspiration, made a brighter start when Kim Min-jae’s header was cleared off the line by Aubrey Modiba after two minutes, before Lee Kang-in fired ​over from inside the ​penalty area shortly afterwards.

South ⁠Africa gradually grew into the contest and nearly struck in the 19th minute when Maseko raced onto a through ball, only for Lee ​Gi-hyuk to produce a superb last-ditch tackle.

Goalkeeper Kim Seung-gyu then made an ​excellent double ⁠save, first denying Thalente Mbatha before smothering Evidence Makgopa’s follow-up effort.

After soaking up the early pressure against a South Korea side that struggled to create clear openings, even with captain Son coming on at ⁠halftime, ​South Africa deservedly found the breakthrough.

Moremi slipped a precise ​pass into Maseko, who shifted the ball onto his left foot before drilling a low finish into the bottom right-hand ​corner to send his side into the last 32.
