World Cup 2026 Day 1 Results: Mexico and South Korea Win in Group A

World Cup 2026 Opening Day Recap

The 2026 FIFA World Cup is underway, and the opening day delivered drama worthy of the occasion. Two matches, five goals, three red cards, a tearful first World Cup goal for a striker who nearly lost his life, and a comeback from a team that refused to quit. Group A served up entertainment from the moment Shakira and Burna Boy finished the opening ceremony at Estadio Azteca to the final whistle in Guadalajara.

Mexico set the tone with a commanding 2-0 victory over South Africa in Mexico City, though the match will be remembered as much for the cards as the goals. Hours later, South Korea overturned a deficit to beat Czech Republic 2-1, showcasing the technical quality that makes them a genuine dark horse in this tournament.

For anyone tracking live World Cup scores, June 11 was the start of a five-week festival of football. Here is the full breakdown of both matches, the key moments, and what the results mean for Group A.

Mexico 2-0 South Africa: Three Red Cards at Estadio Azteca

Mexico's World Cup could hardly have started better. Julian Quinones fired the hosts ahead after just nine minutes, capitalizing on a disastrous mistake by South Africa midfielder Yaya Sithole to send a sold-out Estadio Azteca into delirium. Raul Jimenez sealed the result with a 67th-minute header at the back post, and Mexico walked off with three points and a clean sheet.

The scoreline does not capture the chaos. Three players were sent off in a match that matched the total straight red cards from both the 2018 and 2022 World Cups combined. Gary Neville described it as a game that "didn't feel like it had three red cards in it," but referee Wilton Sampaio saw things differently.

Mexico were the dominant side throughout. Quinones struck the post in the first half, Jimenez was denied twice by goalkeeper Ronwen Williams, and Alberto Fidalgo missed a chance when South Africa's attempted build-up play from the back went wrong again. The score could easily have been four or five.

South Africa barely threatened. Their best moments came from set pieces and long throws, the kind of direct approach that worked once against the run of play but never looked like a sustainable strategy against a Mexico side playing with pace and purpose on home soil.

Raul Jimenez Scores First World Cup Goal

The moment that will linger longest from the opening match was not a red card or a defensive error. It was Raul Jimenez heading home Roberto Alvarado's cross at the far post, then standing still for a moment before the emotion overwhelmed him.

Jimenez is 35 years old. He suffered a serious head injury in November 2020 that left him with a fractured skull and sidelined him for months. The road back to fitness was long and uncertain. To score his first World Cup goal, at the Estadio Azteca, in the opening match of a tournament Mexico is co-hosting, was the kind of moment sport exists to create.

"That is likely to be the greatest moment of his footballing life," said Neville on commentary. The tears in Jimenez's eyes told the story better than any words could. He had missed chances earlier in the match, denied by Williams on two occasions, but kept pushing. The header was not spectacular in execution. It was a simple finish at the back post. But the significance was enormous.

Jimenez now has 36 international goals for Mexico. This one will sit at the top of the list regardless of what happens next. For Mexico, having a striker playing with that kind of emotional fuel could be a significant asset as the tournament progresses.

Three Red Cards: Were the Referee Decisions Correct?

The first red card was straightforward. Yaya Sithole, already responsible for the mistake that led to Mexico's opening goal, brought down Bryan Gutierrez on the edge of the box as the last defender in the 50th minute. It was a desperate lunge from a player whose afternoon had already spiraled out of control. Referee Sampaio reached for the red card immediately, and no one argued.

The second was more controversial. South Africa substitute Thembo Zwane swung an arm at Roberto Alvarado while challenging for the ball in the 82nd minute. The on-field decision was play on, but VAR intervened and Sampaio was called to the monitor. After reviewing the footage, he decided Zwane had struck Alvarado in the face and sent the substitute off.

Neville thought it was harsh: "He's just gone across and trying to leverage him to push away. It's not quite a slap." Roy Keane focused on the self-destruction: "It's hard enough for a manager to win football matches, but to self-destruct like that has no chance."

The third red card was perhaps the most debatable. Mexico defender Cesar Montes hacked down Khalisu Madau on the edge of the box as South Africa launched a counter-attack. Madau still had a long way to go, but Sampaio judged it a denial of a goalscoring opportunity. Even after a VAR check, the decision stood. Neville called it "lazy defending" but also compared it to "the classic 1980s, 1990s tackle" that used to be routine.

Three red cards in one game sets a tone for the tournament. Whether that tone is about strict officiating or unnecessary controversy depends on your perspective. What is certain is that referees at this World Cup are going to be under intense scrutiny from day one.

South Korea 2-1 Czech Republic: Comeback in Guadalajara

If the opener in Mexico City was about chaos and cards, the second Group A match in Guadalajara was about quality and character. South Korea fell behind to a Ladislav Krejci header from Vladimir Coufal's long throw in the 59th minute, a goal that came entirely against the run of play. South Korea had been the better team for an hour. They had nothing to show for it.

Eight minutes later, In-Beom Hwang changed everything. Receiving the ball from Kang-In Lee on the left side of the box, Hwang cut inside and clipped a beautifully deft finish inside the far post. It was the goal South Korea's dominance deserved, and it shifted the momentum permanently.

Tomas Soucek thought he had restored Czech Republic's lead when he headed in from another set piece, but the West Ham midfielder was flagged offside. South Korea made the reprieve count. In the 80th minute, Hwang drove forward and squared for substitute Hyeon-Gyu Oh, who converted from close range to complete the turnaround.

The match winner almost did not play. Oh revealed after the game that he had been running a temperature of 38 degrees in the build-up and questioned whether he could even take part. His goal, and his willingness to play through illness, spoke to a team spirit that could carry South Korea deep into this tournament.

Heung-Min Son, the face of South Korean football, had a frustrating evening in front of goal. Five of his six shots missed the target, and Kovar denied the other. That South Korea won anyway, with the supporting cast producing the decisive moments, is a testament to the depth of talent at manager Myung-Bo Hong's disposal.

In-Beom Hwang and Kang-In Lee Stand Out

While Son grabbed the headlines before the match, it was In-Beom Hwang and Kang-In Lee who delivered on the pitch. Hwang scored the equalizer and assisted the winner, a direct involvement in both goals that earned him player-of-the-match honors. His goal was technically superb, the kind of composed finish under pressure that separates good players from match-winners.

Kang-In Lee, the Mallorca playmaker, was the creative heartbeat of the team. He forced the first save of the match with a long-range effort, provided the pass for Hwang's equalizer, and completed 92 percent of his passes across the 90 minutes. His ability to find space between the lines and play forward under pressure was the key difference between the two sides.

The pair combined for the winning goal in a move that summed up South Korea's approach. Quick thinking, precise passing, and a willingness to commit bodies forward. Czech Republic, for all their grit, had no answer. Their direct style produced one moment of joy from a long throw but nothing else of substance in open play.

South Korea's 464 completed passes to Czech Republic's 242 tells the story. This was not a lucky win. It was a deserved one, built on technical superiority and the belief to keep playing their way even after falling behind.

Group A Standings After Matchday 1

The opening day results leave Group A with a clear top two and two teams already playing catch-up.

1. Mexico - 3 points, +2 goal difference, 2 goals scored
2. South Korea - 3 points, +1 goal difference, 2 goals scored
3. Czech Republic - 0 points, -1 goal difference, 1 goal scored
4. South Africa - 0 points, -2 goal difference, 0 goals scored

Mexico top the group on goal difference courtesy of their clean sheet. South Korea's two conceded goals mean they trail by one on that metric, but the manner of their victory was arguably more impressive, coming from behind against organized opposition.

For South Africa, the situation is already urgent. Zero points, zero goals, and two players suspended for the next match after red cards. Manager Hugo Broos faces a selection crisis before his team even has a chance to reset. Czech Republic at least scored and pushed South Korea close, but Ivan Hasek's side need a result quickly to avoid falling too far behind.

Under the new 48-team format, the top two from each of the 12 groups qualify automatically for the Round of 32, along with the eight best third-placed teams. That third-place safety net means a single bad result is not necessarily fatal, but neither South Africa nor Czech Republic will want to rely on it.

What Comes Next for Group A

Matchday 2 in Group A features two fixtures that could go a long way toward deciding who advances. Mexico face Czech Republic in a match where the co-hosts will be heavy favorites to make it two wins from two and secure their place in the knockout rounds. Another Quinones-Jimenez partnership up front, combined with home support, makes Mexico the team to beat.

South Korea against South Africa is the more intriguing contest. South Korea's technical quality should give them the edge, but South Africa's physicality and directness could cause problems if they can keep eleven players on the pitch. The suspension of Sithole and Zwane forces Broos into at least two changes, which may actually help if the replacements bring more composure.

Both matches take place on June 17. With the top two advancing automatically and eight third-place teams also qualifying, a win for either Mexico or South Korea would virtually guarantee a spot in the Round of 32. For Czech Republic and South Africa, it is already must-not-lose territory.
