Lionel Messi’s first MLS playoffs began with momentum and mammoth expectations. They ended Saturday with a stunning upset and a GOAT’s whimper.

Messi and Inter Miami, the history-making top seed, crashed out in the first round with a second consecutive loss to Atlanta United — who barely snuck into the playoffs with a losing record and negative goal differential.

Messi, who’d been silent in a Game 2 loss, got his first playoff goal to level this decisive Game 3 at 2-2. But Atlanta responded; Bartosz Slisz snatched the lead back with a 76th-minute header; and the visitors sent shockwaves through American soccer with a 3-2 upset.
