Querétaro mounted a valiant comeback attempt but a red card allowed Necaxa to retake control, with the Rayos earning a 2-3 win on the night and booking their spot in the semifinals with a 6-2 aggregate victory.
The Gallos Blancos needed to win at least 3-0 in order to overturn the first leg deficit, and they ame out attacking as they looked to do exactly that. It took just four minutes for Querétaro to get on the board, as Marcel Ruiz headed home a cross from Ayron del Valle to make it 1-0 (1-3) early on.
That goal raised Querétaro’s hopes, which got even higher in the 17th minute. Alonso Escoboza sent a cross into the box, which was deflected away but still fell for Jeison Lucumí, who headed it home to make it 2-0 (2-3) and bring the hosts within striking distance of the semifinals.
It all went off the rails for Querétaro in first-half stoppage time, though, when after VAR review Luis Romo was sent off, leaving the Gallos to try to complete the comeback with just 10 men.
Querétaro kept trying to press forward, but with their numerical disadvantage that left them increasingly vulnerable to counterattacks. Finally, in the 79th minute, Necaxa did what they had been threatening as Cristian Calderón scored for the visitors to make it 2-1 (2-4) and all-but-guarantee the Rayos would advance.
A demoralized Querétaro soon let in another, with Luis Felipe Gallegos finishing off a cut-back to make it 2-2 (2-5) in the 86th minute.
Three minutes later, Necaxa scored again to take the lead on the night, with Maximiliano Salas beating Gil Alcalá with his shot from outside the box to make it 2-3 (2-6).
With the 2-3 (2-6 aggregate) win, Necaxa advances to the semifinals while Querétaro is eliminated.
