Co-hosts Mexico became the first team to reach the knockout rounds of the World Cup with a 1-0 win over South Korea at a delirious Guadalajara Stadium on Thursday. Luis Romo’s goal just after half-time put Mexico through as Group A winners with a match to go following a goalkeeping clanger. In contrast, Mexico stopper Raul Rangel made a superb double save in the dying minutes to preserve their lead.
