Iqraam Rayners scored from point-blank range in the 36th minute to give Mamelodi Sundowns a 1-0 win over Ulsan HD after an hour-long weather delay in the group stage of the Club World Cup on Tuesday night.
Sundowns have continued to grow in stature both on the domestic front and across the African continent, with their first win making them leaders of their group. 
Mamelodi was aggressive on offense in front of a crowd of fewer than 1,000 fans at the 25,500-person capacity Inter&Co stadium, but the South Korean club had the first real scoring chance of the game on a counterattack when Erick Farias missed the one-time shot just over the crossbar.
Ulsan nearly scored the equalizer in the 80th minute as winger Matías Lacava took a dangerous shot directly in front of the Mamelodi goal, but goalkeeper Ronwen Williams stifled the chance.
With the win, Mamelodi sits atop the Group F standings with three points. Ulsan is now last in the group with zero points. Mamelodi and Ulsan continue their group stage campaigns June 21 with matches against Borussia Dortmund and Fluminense respectively.
This tournament marks the Brazilians’ second appearance on the global stage, having previously featured in 2016 under the leadership of Pitso Mosimane, who guided the club to their first-ever CAF Champions League title earlier that year.
