Chivas left it until injury time to grab a controversial goal and get a 1-0 victory over Mazatlan. It looked like it would be a third straight scoreless match in Group B until the 91st minute had Chivas scoring a goal that was at first disallowed and then allowed to stand by the referee. Chivas was making their debut in the competition and climbed all the way to top of the group. They will now play against Santos on Monday while Mazatlan waits until Tuesday to play against Atlas.
The first half started with Chivas coming out with a strong lineup, while Mazatlan had a more diverse one, with lots of regular substitutes in it.
