Club León moved in front against Tigres UANL in their Apertura 2026 Matchday 13 meeting at Estadio Universitario in Nuevo León.
The visitors capitalised on a defensive lapse involving goalkeeper Nahuel Guzmán to take a 1-0 lead, as reported by Marca.
The setback arrived despite a strong opening from Tigres, who had started the match well before the error changed the scoreline.
Pressure Builds on Tigres in Liguilla Race
The goal landed at a critical stage of Tigres' campaign under head coach Victor Manuel Vucetich.
With qualification for the Liga MX Liguilla at stake, the Monterrey-based club had little room for further dropped points in the tournament.
Marca reported that both a defeat and a draw could complicate Tigres' chances of reaching the postseason.
Their standing in the table made securing points in the remaining matches increasingly important to those ambitions.
León, for their part, paired defensive organisation with opportunistic play to keep the hosts under pressure after scoring.
Tigres were left chasing the match following their positive start, while León's ability to protect the advantage became the central challenge for the home side as the contest continued.
