Jonathan Urretaviscaya scored a wonder goal in the second half to help Pachuca earn a 2-1 win at Chivas, who were left to rue missed chances after playing most of the second half with an extra man in a highly entertaining match at the Estadio Chivas.
Chivas controlled much of the early play and took the lead when Hedgardo Marin headed the Rebaño Sagrado in front from an Edwin Hernandez corner.
Soon after the half-hour mark, Erick Aguirre burst through the left-wing and played in Franco Jara, who found himself on goal to level the score.
Pachuca were more composed after half-time but found themselves in trouble when Hirving Lozano received his marching orders for two yellow cards in a matter of ten minutes.
