Atlanta United snatched a dramatic last-gasp 2-1 playoff victory over Inter Miami on Saturday, jolting Lionel Messi's hopes of leading the Florida club to MLS Cup glory. Portuguese winger Xande Silva blasted home a sensational winner for Atlanta in the fourth minute of stoppage time in front of 68,455 home fans at the Mercedes-Benz Stadium to level the best-of-three postseason series 1-1 and set up a winner-take-all game three in Miami next Saturday. Top seeds Miami, 2-1 winners in game one last week, had looked to be heading for a series victory after taking the lead through Paraguay international David Martinez in the 40th minute after a terrible blunder by former US goalkeeper Brad Guzan.
