Argentine striker Lucas Di Yorio’s first-half goal proved decisive, Los Angeles goalkeeper John McCarthy failing to grasp the South American forward’s scuffed shot for the game’s only goal in the 20th minute.
The win ended Leon’s long wait to taste success in the CONCACAF region’s premier club competition after finishing runners-up in the 1993 tournament in its old format.
The win means Leon will qualify for this year’s FIFA Club World Cup as well as the expanded 32-team edition of the event planned for 2025.
But the loss marked another agonizing near-miss for LAFC, who were also bidding to win the tournament for the first time, three years after losing in the 2020 final to Mexican side Tigres.
Roared on by their vociferous home support in a crowd of 22,413, Los Angeles should have taken the lead after just 10 minutes only for defender Aaron Long to head wide from Carlos Vela’s free kick with the goal at his mercy.
Instead it was Leon who took the lead on 20 minutes with their first serious foray into Los Angeles territory.
Right back Ivan Moreno surged into space down the right and crossed for Di Yorio, who hooked his shot untidily at LAFC keeper McCarthy.
McCarthy flapped nervily at the effort and could only look on in disbelief as the ball spilled into the net.
That left Leon 3-1 up on aggregate and suddenly the Mexican side attacked with vigor.
Moments after the goal, Victor Davila almost doubled the Leon lead with a shot that whistled just past the boast.
Los Angeles upped the tempo but as in their 2-1 first leg defeat, were let down by a lack of precision close to goal.
Denis Bouanga shot high and wide from long range in the 27th minute before seeing a deflected free-kick saved by Leon goalkeeper Rodolfo Cota shortly afterwards.
Kellyn Acosta had LAFC’s only other chance of note in the first half, dragging a shot from outside the area wide of the post.
Los Angeles coach Steve Cherundolo reverted from 3-5-2 to his team’s more familiar 4-3-3 formation after halftime, but the change had little impact as Leon kept the home side at arm’s length in a scrappy second half.
Long missed another headed chance on 65 minutes, directing his header over the bar from the edge of the six-yard box.
Los Angeles finally began to attack with urgency in the closing stages.
Substitute Kwadwo Opoku darted into the area in the 79th minute, but Cota advanced swiftly off his line to snuff out the threat.
Bouanga then rippled the side netting with a fierce shot and substitute Timothy Tillman should have done better with a close range header deep into stoppage time.
