Santos, released by Dallas in the off season, opened the scoring in the 28th minute, but Blas Perez levelled four minutes before the break.

Nick DeLeon re-established the lead on the hour mark, before Danny Cruz stretched the lead six minutes later and Santos grabbed his second in the 73rd minute.

A miserable day for Dallas was complete four minutes later when Daniel Hernandez was shown the red card.
