Luis Suarez and Jordi Alba handed Inter Miami a winning start to their MLS playoff campaign, with their goals helping down Atlanta United 2-1 at the Chase Stadium.
After already winning the Supporters' Shield and setting a new MLS single-season points record, the Herons took a 1-0 lead in the best-of-three series ahead of Game Two.
The hosts needed just over a minute to take the lead when Diego Gomez picked out Suarez, who prodded the ball beyond Brad Guzan early on.
David Martinez then saw his effort strike the woodwork, but Miami were unable to make their sustained spell of pressure count as visiting forward Saba Lobjanidze levelled the contest in the 39th minute.
But the hosts restored their advantage just before the hour-mark when Lionel Messi picked out Alba, who struck a fierce effort from distance which proved to be the winner.
Miami should have had a more comfortable advantage, but were met with the imposing figure of Guzan, who made nine saves during the contest to keep the hosts at bay.
Data Debrief: Welcome to Miami
Having topped the Eastern Conference with 74 points, Miami are expected to reach the showpiece match, and their display proved why they were one of the best teams in the MLS during the regular season.
The hosts ended the contest with an expected goals (xG) total of 3.38 from their 22 shots, 12 of which were on target and 14 of their efforts were inside the Atlanta box.
And though not getting himself on the scoresheet, Messi once again showcased his class. The Argentine registered a team-high 1.26 xG to Inter Miami's total, while also recording more shots on target (five), more touches in the opposition box (13) and creating more chances (five) than anyone on the pitch.
