Martin Cauteruccio struck early in the second half as Cruz Azul edged Chivas 1-0.
Under the torrential rain of Guadalajara, Chivas were bidding for their first win of the season and only their second league win at home all year.
And it was the hosts who showed all the attacking intentions early on, but it was Cruz Azul who had the better opportunities. In particular, la Maquina carried their own threat on the breakaway.
After a scoreless first half, Cruz Azul manger Pedro Caixinha surprised many by replacing starting forward Milton Caraglio for Martin Cauteruccio at the break.
