Russell Fuller
BBC tennis correspondent on BBC Radio 5 Live Sports ExtraI would be gobsmacked if he won the title and there would need to be a remarkable run of results for it to happen, but Tsitsipas has been in a couple of Grand Slam semi-finals before and is that talented that now we're at the point that every Grand Slam could be his big breakthrough.
Although It would be a phenomenal achievement to beat Nadal, Medvedev and then Djokovic in a row.

Ferocious from the Spaniard, wrong-footing Tsitsipas and making him dance on the baseline.
Watch those ankles! Nadal screams to a hold.

Great exchange.
Stefanos Tsitsipas thinks he beaten Rafael Nadal with a passing backhand but the Spaniard plucks it out of the Melbourne sky like prime Michael Jordan reaching for a slam dunk.
Nadal hooks a superb backhand right on to the chalk for 30-0.

Ah, here he is. First he has to align the water bottles. Obviously.
Nadal finally gets us rolling again, Tsitsipas batting into the net for 15-0, before they exchange errors for 30-15.

Tsitsipas has had enough of sitting and jogs to the baseline while we wait for Nadal. No rush, Rafa.

Excellent from the Greek.
Huge serve, complemented by a wonderful forehand winner.
And in a sight you don't often see, Rafael Nadal frames a forehand high into the Rod Laver Arena stands.
Two set points.

Nadal 6-3 6-2 6-7 (4-7) 4-5 Tsitsipas*
A little overzealous from Stefanos Tsitsipas, winding a forehand into the tramlines.
The next one is right on the money, though Rafael Nadal thinks it's wide... 15-15.
'Special retrieving from Tsitsipas'published at 11:54 Greenwich Mean Time 17 February 2021
Andrew Castle
BBC Sport tennis commentator on BBC Radio 5 Live Sports ExtraVery special retrieving, great desire and fitness from Tsitsipas, covering every inch of the court and making Nadal hit that extra ball.
Nadal is making mistakes he wasn't in the first two sets. Nadal at the age of 34 - how does he feel now? Will the adrenaline kick in and enable him to fight again?

So Stefanos Tsitsipas will serve for the fourth set, to level the match, having been two down.

Tsitsipas asks for a bug to be swept off court as he awaits the Nadal serve at break point.
He manages to engage the Spaniard, sticking in the point and forcing the second seed deep, and Nadal fires long! The Greek gets his break.
