Atlanta United's inaugural MLS season will see the club feature in the playoffs following its win over the Philadelphia Union, while a Kaka double inspired Orlando City to a crushing victory.
Led by former Barcelona and Argentina coach Gerardo Martino, in-form Atlanta made sure of a postseason berth with four regular-season fixtures remaining via a 3-0 victory on Wednesday.
Julian Gressel, red-hot Venezuela international Josef Martinez and Jacob Peterson were on target as Atlanta — which became the first expansion side since 2009 to reach the playoffs — extended its unbeaten streak to seven games, a run that has resulted in five clean sheets and 24 goals scored.
More than 43,000 fans packed into the new Mercedes-Benz Stadium, where Gressel opened the scoring with the outside of his boot in the 27th minute.

Martinez's 18th goal of the season made it 2-0 six minutes later after the Venezuelan forward rifled a powerful low effort across Union goalkeeper Andre Blake and into the net.
After Hector Villalba's second-half goal was ruled out following a video review, Peterson came off the bench to complete the scoring with two minutes remaining.
