The American uprising is genuine – and so, too, is Sebastian Korda.

The son of 1998 Australian Open champion Petr Korda has been the source of endless hype, but there is an increasing amount of substance to go with it.

Korda unleashed a lethal mix of easy power, acute angles, changes of pace and slick court craft to defeat seventh seed Daniil Medvedev 7-6 (9-7), 6-3, 7-6 (7-4) and dash the Russian’s hopes of a hat-trick of Melbourne Park final appearances.

Medvedev has now lost before the quarter-finals at his past three grand slams after ascending to the top ranking twice last year and this is his worst Open result since losing in the second round in 2018.

Korda is the first United States men’s player into the last 16 – a feat he already achieved at the French Open and Wimbledon – but there will be at least two countrymen joining him due to all-American match-ups.

Frances Tiafoe and Mackenzie McDonald exited the tournament on Friday, but an impressive eight Americans advanced to the round of 32, even with their No.1 player, top-10 star Taylor Fritz, suffering a shock loss to Australia’s Alexei Popyrin.

That depth in the US men’s game is raising hopes they can finally end the nation’s grand slam title drought, which extends to former world No.1 Andy Roddick’s 2003 US Open triumph.
