As South Korea's sole threat, it was fitting that Tottenham striker Son gave his side fleeting hope in added time with a sublime, curling strike from 25 yards. The Mexicans have been eliminated in the Round of 16 in the last six appearances at the World Cup, and the wages on them to make it to the last eight in Russian Federation are +200.
On the TV-only side, Telemundo averaged 6.6 million viewers for Mexico-South Korea in the two-hour match window and 6.02 million for the full coverage, ranking as the network's second most-watched sporting event ever to last Sunday's Mexico-Germany match. Hernandez officially put the match out of reach in the 66 minute when tallied his 50 career goal in a Mexico shirt with a rocket into the right corner. South Korea is a +460 underdog, while a draw bet is listed at +253.
Mexico were expected to be the dominant force ahead of the game and that's exactly how things started, yet it was the Koreans who had the best early chances in the opening quarter of the contest - Ki Sung-yueng's header saved by Guillermo Ochoa the pick of the bunch.
Carlos Vela gave Mexico the lead with a penalty after Korean defender Jang Hyun-soo blocked Andres Guardado's cross with his arm inside the area, before the nation's all-time leading goalscorer Javier Hernandez doubled their lead in the second half with his 50th global goal.
The score in the match, which became the jubilee, 150-m, for the captain of Mexico's Andres Guardado in the national team, was opened in the 26th minute.
A win gave Mexico six points in Group F - and it's looking likely that Mexico can emerge as the victor of the group and avoid a Round of 16 showdown with Brazil.
Sweden are the final group-stage opponents for Mexico, with Osorio keen to remain focused on that test after celebrating another World Cup win.
Nonetheless, Mexico did double their lead in the 66th minute with a counterattack that brought back memories of their victor against Germany.
Although the FMF and Liga MX clubs have traditionally done a poor job of dealing with the issue, there now seems to be more effort from the federation and players to stamp out the chant in the World Cup.
It's the 50th career global goal for Hernandez, known as "Chicharito".
