Atlanta United defender Robinson came up with the decisive goal with a header from Kellyn Acosta's left-flank free-kick, denying Mexico their 12th continental crown.

The Gold Cup triumph backs up US's CONCACAF Nations League success in June, also beating El Tri in extra-time in that final 3-2.

Mexico had beaten USA in the 2019 Gold Cup final 1-0 in Chicago, with the two nations sharing the past 10 titles.

The victory is a major triumph for Gregg Berhalter's side as the US move on from missing out on qualification for the 2018 World Cup.

It was also US's fifth 1-0 victory throughout the Gold Cup, having beaten Qatar and Jamaica in the knockouts by the same scoreline.

Robinson was the hero with the winner but goalkeeper Matt Turner was exceptional, as both sides blew chances throughout.

Eryk Williamson had the first chance of the game, with a bouncing volley easily collected by Mexico goalkeeper Alfredo Talavera, while down the other end Hector Herrera had a header saved by Turner.

US should have taken the lead in the 26th minute when Sebastian Lletget stole the ball on the edge of the box and set up Paul Arriola but his low effort hit the post.

Turner was crucial in keeping it 0-0 with two key saves to deny Mexican forward Rogelio Funes Mori before Edson Alvarez shot marginally wide.

Orbelin Pineda snatched at a golden chance in the 50th minute, pushing his shot wide when unmarked inside the box, while Alvarez desperately blocked Matthew Hoppe's 71st-minute chance.

Arriola spurned another chance from a free-kick which fell kindly to him as Talavera smothered his effort on goal.

In extra-time, Talavera made a good low save to deny Gyasi Zardes in the 106th minute, before Robinson's header which settled the contest.
