Mexico becomes the first team to reach the World Cup knockout phase after defeating South Korea 1-0 on Thursday. Multiple outlets report the match is played at Guadalajara Stadium, with Mexico co-hosting the tournament. The win is secured when Mexico capitalizes on a defensive error by South Korea, allowing Mexico to take the lead and then manage the game to preserve the one-goal advantage. Reports describe the result as advancing Mexico to the knockout stage ahead of other teams, making them the first side to clinch progression. Coverage across outlets focuses on the same key elements: Mexico’s first-ever/earliest qualification to the knockout phase, the 1-0 final score, the decisive role of South Korea’s defensive lapse, and the fact that the qualification comes through results in the group stage on Thursday. No sources provided here indicate any controversy, change of score, or alternative goal-scoring details beyond South Korea’s blunder and Mexico’s 1-0 victory.
