*Tiafoe 3-6 3-5 Nadal
A return of serve from Nadal is so good that it surprised Tiafoe, who moves forward and tamely guides his shot into the net.
Tiafoe is too quick through some of these shots and he backhands a volley into the net to give Nadla two set points.

Chris Beck: You get the feeling Tiafoe has to be at least 40-15 up to have any chance of a break. Giving away one break point just doesn't faze Nadal at all.

*Tiafoe 3-6 3-5 Nadal
Flat hitting from both men, and Rafa turns his back in disgust as his backhand slides over the baseline.
It's 30-30 and Nadal swings an almighty ace right through Tiafoe's swishing racquet. And again!
Game, Nadal. One more and he'll take a two-set lead.

*Tiafoe 3-6 2-4 Nadal
Nadal drags a volley down into the net and looks furious with himself, but 15-15 comes up with a long Tiafoe service return.
Tiafoe goes for the corner of the court and Nadal, anticipating it, angles in a beauty of a winner, and that helps him towards a hold.

Tiafoe 3-6 2-3 Nadal*
Now yesterday, when Daniil Medvedev let some chances slip on Novak Djokovic's serve, he was broken straight away.
Frances Tiafoe, however, produces a glorious backhand winner to go 40-0 up, and a long return of serve from Nadal secures a love hold.

Whoopsie. That's, er, a horrible hoick from Tiafoe down the line, and it's given Nadal the advantage.
And Nadal comes through as a Tiafoe backhand is flapped into the net.

Frances Tiafoe gets a look at a Nadal second serve, but he can't make it out.
Advantage, Rafa - and that's a divine shot down the line from Tiafoe, surprising Nadal, who tries to rally and ends up working a backhand into the net.
On we go.

A chance for Rafa Nadal to hold now, as Tiafoe, up on one knee, hits a forehand out.
Oh, but Nadal sends an easy backhand long to take us back to deuce!

Deep return from Nadal - and Tiafoe's return goes long!
He challenges anyway but that's out, the ball lobbed over the baseline. Deuce.
