Goals from Andre-Pierre Gignac and Lucas Zelarayan sent Tigres into the Liga MX final following a 3-1 aggregate victory over Leon.
With Tigres holding a 1-0 advantage from the first leg, it was Leon who had the early pressure and the early goal.
A sublime long range half-volley from Luis Montes settled in the back of the net to put the aggregate score tied at 1-1.
However, at the stroke of halftime, a Jorge Ivan Estrada pass allowed Andre-Pierre Gignac to advance inside the area and fire home the go-ahead goal.
Gignac’s goal was shrouded in controversy as Leon felt there was an offside in the build-up.
Early in the second period, the visitors continued to press, and Luis Montes came close to grabbing a second with a looping shot from outside the box.
In the 70th minute, Tuca made a change, Lucas Zelarayan on for Ismael Sosa, and the Argentina made an immediate impact.
Jesus Duenas pulled a ball back for Zelarayan, who nodded home a curling shot past William Yarbrough. His cool finish decisively resolved matters and took the wind out of the visitors, sealing the tie in favor of the hosts.
Tigres will now wait for the winner between Necaxa and Club America.
