Mexico clinches Group A and a spot in the knockout stages with a narrow 1-0 victory over South Korea at Estadio Guadalajara.

Romo's opportunistic finish in the 50th minute was the difference.

The match was a nervy affair, goalless at halftime, with both sides struggling to break through a congested midfield.

The lone goal came after Quinones' cross was unconvincingly spilled by Kim Seung-gyu eight yards out, allowing Romo to volley over his shoulder into an empty net.

South Korea threatened late, with Cho and Yang creating quick chances, but the goalkeeper made incredible reaction saves to preserve the shutout.

Despite a better xG total (0.69 to 0.48), Hong Myung-bo's side couldn't find an equalizer.

Their fate now rests on their final-day encounter with South Africa in Monterrey on June 24.

Mexico, already qualified, will face Czechia in their capital city on the same day.

That concludes our coverage of this FIFA World Cup Group A fixture.

SUB: A defensive move for the hosts as Reyes, a primary back-line player, replaces winger Alvarado.
