La Máquina looked dangerous from the beginning, with their first good chance coming in the 3rd minute; on the counterattack, Roberto Alvarado found Édgar Méndez, but his shot went over the bar. Then, in the 17th minute, Yosimar Yotún forced a good save out of Hugo González as Cruz Azul continued to look for the opener.
The breakthrough came in the 20th minute. Yotún sent a free kick into the box and Milton Caraglio headed it home to make it 1-0 for Cruz Azul.
Necaxa looked for a response, and they had their first notable opportunity of the game in the 26th minute. Kevin Mercado pounced on a defensive miscue by Juan Escober to get into the box and get a shot away, but his attempt was just off target.
The Rayos had another chance to equalize in the 37th, when Mercado took the ball down the wing and sent a low ball in across the six-yard box. Eduardo Herrera was there, but couldn’t put it on frame as the ball rolled past the far post with Jesús Corona beaten.
Then, just before halftime, Cruz Azul struck again. In the 44th minute, Cristian Calderón tried to play the ball back to Hugo González from midfield, but it was easily picked off by La Máquina. Elías Hernández rounded González, who had come far out of his box in an attempt to intervene, and scored on the empty net to make it 2-0.
They scored again just after the second half began, with Méndez finishing off a ball from Adrián Aldrete to make it 3-0 right off the bat.
That early goal deflated Necaxa’s hopes of a comeback, and the Rayos turned their focus to preventing Cruz Azul from running the score up further. They were able to do so for most of the half, but in the 85th minute Juan Escober added an exclamation point to the win with a fourth goal for La Máquina.
