Tigres and Arabe Unido were the winners on Wednesday, as FC Dallas was held in the CONCACAF Champions League.
Tigres kept up their perfect record in the CONCACAF Champions League group stage with a 3-1 home win over Plaza Amador.
Despite conceding a shock opener midway through the first half Wednesday, Tigres — last year's runners-up — recovered to make it two wins from two in Group G.
Humberto Ward scored the opening goal of the game for Panamanian side Amador after 22 minutes, but a Jorge Espericueta spot kick leveled proceedings just before the break.
