The first-round of the A-League playoffs produced four survivors who will take on the top four seeds, which received first-round byes. The quarterfinals — the conference semifinals — will also consist of two-leg series determined by aggregate score.

EASTERN CONFERENCE, First Round
Richmond edges Atlanta

Defenders James Wall (Atlanta) and Peter Luzak (Richmond) scored in a 1-1 first-leg tie. Richmond didn't get the equalizer until the 90th minute despite having outshot Atlanta 25-4. Wall scored off a corner kick and Luzak scored from a long throw-in.

Richmond's Josh Henderson's first-half penalty kick was saved by Atlanta Keeper Jeff Cassar. In the 86th minute, after a Henderson-Cassar collision, both were cautioned and Wall was ejected for the scuffle that followed.

In the second-leg, Henderson struck in the 8th minute and Kevin Jeffrey gave Richmond a two-goal lead late in the first half that it held until Barry Nusum's consolation goal. Richmond gets a date with Charleston.
