*Stefanos Tsitsipas 2-6 2-2 Rafael Nadal
A fist pump from Nadal after he curls an effort around the net post and finds the line from an impossible-looking angle. Nadal then gets a challenge his way and that is 0-30. Chance for a break.

Rafael Nadal, once again sprints into the net, Tsitsipas goes for the lob but overcooks it, sending it long and out. 2-2.

An ace out wide is challenged by Tsitsipas. All eyes are on the screens, but the original call is correct and that's a wasted challenge. A lovely low forehand volley from Tsitsipas keeps the game alive though. (40-30)

Nadal is sending Tsitsipas scurrying around the court with a number of cross-court shots. The Spaniard then dances into the net and is in the way to block a passing attempt. That's eight of nine shots won at the net from Nadal. (30-0)

Back in the present, and Tsitsipas is doing everything he can to stay in this match. Remember, he lost the opening set against Roger Federer on Sunday and we all know what happened after that.
Nevertheless, a fine service hold to 15.

What a story it will be if Petra Kvitova wins the women's title on Saturday, after reaching her first Grand Slam final since being stabbed.

Nothing gets a tennis crowd quite as excited in a changeover than Rafa Nadal whipping off his shirt.
Wonder how many orange sleeveless tops he has in the bag? Five? Potentially one a set?

A service game to love from the 20-year-old as a two-handed backhand from Nadal goes wide. No sense of worry of panic from Tsitsipas after losing that opening set. Forget about it and move on.

Nadal is on a mission. Maybe Roger Federer told Nadal to avenge his defeat by Tsitsipas and give a lesson to those young players
*Stefanos Tsitsipas 2-6 Rafael Nadal
Relentless from Rafa so far. How does Tsitsipas get himself back into this one?

Earlier on, Naomi Osaka moved into her second consecutive Grand Slam final with a 6-2 4-6 6-4 win in a thriller on Rod Laver Arena...
The match between Pliskova and Osaka was the best women's match I've ever seen.
That was incredible in terms of level - 58 winners for Osaka and only 20 unforced errors. I was impressed by Pliskova's resilience - she should have lost in two sets. She kept on finding solutions.
Now it's two players playing at their peak facing each other in the final - Petra Kvitova and Naomi Osaka.
If I have to pick a favourite for the final then I will go for Osaka.
*Stefanos Tsitsipas 2-6 Rafael Nadal
The serve is down the middle, Tsitsipas aims to do some damage with a two-handed backhand return, it is too long and that is set one to Nadal. Thirty-one minutes and Nadal maintains his record of winning each set he has played in this year's tournament.

A Hawk-Eye challenge from Tsitsipas is wasted as the serve clipped the centre line, a lovely volley at the net from a sliding Nadal brings him to set point. (40-15)

So far what is happening in this tournament is no one can compete with Nadal from the back of the court.
A Novak Djokovic v Nadal final will be interesting because Djokovic can compete from the back.

You can hear the Greek fans in Garden Square - just a stone's throw behind Laver - chanting away.
It was like a football terrace down there earlier before the match, sounds even livelier now...

Some fantastic sprinting pace from Rafael Nadal as he gallops to the net and flicks a drop shot over the net after an earlier slice to set up the opportunity. Tsitsipas lunges at it, can't get there and Nadal has a double break and is next serving for the opening set.

Meanwhile, another break point for Nadal.

She was really nice - she has a passion for tennis.
