Only had to deal with two shots on target, and was up to the task.
Made an impression going forward in the first 45, delivering the cross for Peralta's opener. Yet another good fullback option for Herrera.
Only played the first half, and despite a poor clearance and a few moments where his lack of speed was exposed, didn't cost his side any goals
Despite not playing for Porto, Herrera wants the youngster to be an important player for Mexico, and handed him the armband after Marquez went off. Didn't exactly cover himself in glory, but helped keep a clean sheet.
The Mexican back line wasn't breached, but it didn't look great in the opening minutes. Poor clearances, missed marking and poor tracking of runners could have cost El Tri against a better offense.
Was only given the first half by coach Miguel Herrera, but absolutely made the most of it. Was involved in both of Mexico's goals, feeding Ponce for the cross and then finding Pulido (perhaps after a missed offside call) for the second.
Had a nice cross early on that nearly found Peralta on the far post, but looked a bit awkward in the center of the midfield. Improved when he was allowed to play wide, assisting Pulido's second.
A hat trick on his debut, an absolutely perfect night. Right place at the right time to poke home over the line for the first, a fine thumping shot for the second, and a poacher's strike from farther out to cap the trio.
Showed again why he's the most important player on this Mexico team right now. Took his goal well, with a fluid turn to lose his marker before a solid strike on target.
Had some awkward moments, including an embarrassing miss when he came out for a corner, and he was too easily bypassed for the second goal.
Possibly the most encouraging performance from South Korea. Seemed to pop up everywhere, on both sides of the ball. Looked far more important than his limited international experience would indicate.
Korea was let down by its defensive unit, and Kang was the worst offender. On offense, put a free header into the Alamodome turf, and was too easily brushed aside by Peralta.
The Korean left back had a better night than his compatriot on the right, at least.
Was a physical presence in the midfield, and saw a decent effort from distance just miss the target in the early going.
The scoreline was all Mexico, but the Korean midfield was in control for the opening half hour.
Was one of the few Korean players to actually force Talavera into a save. It might have troubled the keeper more had Kim not put it right into his body.
Was the favored option on the right side, and caused a few headaches with his movement. Managed a couple of shots not too far off target.
Won a few headers early, but was never really as much of a threat as he was expected to be. Removed at halftime.
The Korean midfield, playing in 4-4-2, outnumbered Mexico's 5-3-2, and the man advantage told as the visitors caused El Tri problems on the transition.
Was given a chance to help Mexico see out the win. Did so.
Came on for Marquez and helped usher the clean sheet home.
Came on as a second-half sub for Vasquez as El Tri was in the ascendancy.
Good off the bench, his run from the midfield led to Mexico's fourth.

Came on as a sub and helped force Mexico's fourth as his deflected shot fell for Pulido.
