Atlanta late show stuns Messi's Miami

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.

Guzan could only watch in horror after he bungled a routine clearance from his own penalty area, allowing Federico Redondo to gather possession and square a pass to Martinez who finished into an empty net for 1-0.

But Atlanta launched a furious second-half onslaught as they battled to save their season and were rewarded when Derrick Williams crashed in a header to equalize in the 58th minute.

An end-to-end game saw both teams create chances thereafter, and Georgia international Saba Lobjanidze almost hooked in a goal for Atlanta in the 89th minute only to see his shot tipped onto the woodwork by Miami goalkeeper Drake Callender.

The game looked poised to go to a penalty shoot-out when Atlanta launched a desperate last raid on the Miami goal, and when Aleksey Miranchuk found Silva, the Portuguese substitute made no mistake and buried a winner into the top corner.

"Words can't describe it, they're such a resilient group," Atlanta coach Rob Valentino said after the win.

"I said to the team before the game it's everybody together, it's not going to be one person. And then a substitute comes on and wins us the game."

In other MLS playoff action on Saturday, New York City FC defeated FC Cincinnati 3-1 to force a decisive game three in their first-round series.
