Pachuca moved into the Liga MX's top three after they survived a late rally to down Club America 4-1 at the Estadio Azteca on Saturday.
Los Tuzos continued their bright start to the season, as a Ventura Alvarado own goal and Franco Jara gave Pachuca a 2-0 lead at the half.
Club America dully pulled within one, but Hirving Lozano and Chivas loanee Victor Guzman added to Las Aguilas' misery to run away with a memorable victory at the Azteca.
Meanwhile, Cruz Azul's frustrations endured despite taking a first-half lead over Leon. Juan Antonio Pizzi's side showed more intent in the second half, and behind two goals from Fernando Navarro, La Fiera ran away with a 3-2 thriller over Cruz Azul, who remain winless after three weeks.
Joining Leon and Pachuca in the top three is Monterrey. The Regiomontanos needed just a lone goal from new signing Carlos Sanchez to remain perfect in the campaign.
Elsewhere, it was a performance of mixed-feelings as Chivas drew 2-2 with the current champions Tigres. Matias Almeyda's side had taken a 27th minute lead through Orbelin Pineda, but Fernando Fernandez scored a stunning back-heel to give Tigres the equalizer.
Fernandez then set up Rafael Sobis for Tigres' second before Carlos Cisneros spared Chivas' blushes by scoring his first career league goal.
Chivas yet again let a lead slip, but remain unbeaten after three weeks.
Goal of the week: Fernando Fernandez
