El Tri's form, confidence and collective spirit in Russian Federation surprised everyone in its World Cup opener, and Juan Carlos Osorio's team won't pass up the chance to announce itself as Group F's team to beat when it faces South Korea.
Meanwhile, while the South Koreans are not mathematically out of it - at least until the game between Germany and Sweden later on Saturday - it will take a minor miracle if they are to have any chances of keeping their World Cup dream alive.
This win followed one of the World Cup's most confounding upsets, when Mexico toppled Germany 1-0 in its opener.
South Korea will be eliminated if Sweden wins or draws. Carlos Vela sent Jo the wrong way for the first goal of the game.
Mexico had their second of the game in the 66th minute, however, when Hernandez collected a super pass from Lozano before finishing low into the bottom corner of the net to register his 50th worldwide goal.
This time, the roles were reversed as Hirving Lozano led the charge up the field before feeding a pass to Hernandez, who calmly skipped inside a defender before finishing into the back of the net. "They tend to relax, they tend to lose focus, so every weekend, every match, we insist on being fully focused on not losing that important message", Osorio said.

The South Koreans, who have lost their opening two matches, kept Ochoa under pressure throughout the match with Son often out-sprinting the Mexican defense. A volley from Vela skimmed the bar minutes later.
If Germany fails to win, Mexico locks up a spot in the round of 16.
South Korea will face Germany at the same time in Kazan.
It was Hernandez's 50th goal for his country and his fourth strike at a World Cup, taking him level with Luis Hernandez as Mexico's leading scorer in soccer's global showpiece tournament.
