Novak Djokovic beats Jack Draper 4-6 6-1 6-2 6-2 on Centre Court
*Djokovic 4-6 6-1 6-2 5-2 Draper
But Draper, much to the delight of 7,500 people on Centre Court, gets through another service game, holding to love, to force Djokovic to have to serve this one out.
A great reception for the fans to Draper, but Djokovic is two minutes away from the last 64. Probably.
Djokovic 4-6 6-1 6-2 5-1 Draper*
Hope comes, hope goes. Djokovic sees off the break point and then bolts down a couple of aces to bring his total up to 22.
Djokovic one game from the win.
A rare, unforced error from Djokovic who seems to have all the time in the world to place a two-handed backhand wherever he wants to, but can only pull it into the net. Break point Draper, and it's been ages since we said that.
Tsitsipas 4-5 Tiafoe*
A straight-forward hold for Frances Tiafoe forces Stefanos Tsitsipas to serve to remain in the first set, and he responds accordingly with an ace to get things started.
Tiafoe successfully challenges a call which earns great applause from the crowd, but the Greek keeps his cool to see out the game and Tiafoe will now serve for the opening set.
Another slip on the grass for Djokovic. Considering the amount of tumbles we've seen on this court, it's amazing we've not had any injuries.
Jack Draper then clips the line and gets Hawk Eye to prove it to have 0-30 and a rare sniff of a break. He desperately needs a break here to keep this one interesting.

Djokovic is moving into another gear, getting the feel, the confidence that you can't find in any good practice session.
When he starts raising his fist when winning games, you know he means business.
*Djokovic 4-6 6-1 6-2 4-1 Draper
Just too good. A fine baseline rally is ended when Djokovic wants it to end. He steps forward and punches a brutal two-handed backhand winner down the line.
That's a double break for Djokovic in the fourth.
This one looks all over now.
Break point Djokovic after he mixed it up and produced a brilliant, delicate drop shot.

Djokovic 4-6 6-2 6-1 3-1 Draper*
Draper does take a couple of points off that Djokovic service game, which is an improvement on recent efforts, but it's still not enough and Djokovic now has daylight and can see the finish line. He's three games away from round two.
*Djokovic 4-6 6-2 6-2 2-1 Draper
Hard to see a way back for Draper from here. He's not had a break point chance since the opening set.
Tsitsipas 3-4 Tiafoe*
Tiafoe battles back from 30-40 down on serve to hold again and edge closer to this first set.
There are ominous signs coming from the opposite side of the court as Tsitsipas appears to be finding his rhythm now - although an audacious 'tweener' from the Greek goes long.
Still, he holds, and it's as you were on Court One, with Tiafoe still holding on to his early break.

Now I don't want to get anyone TOO excited, but the covers are coming off on the outside courts.
Which means the thousands here who don't have tickets for the showpiece courts should be about to see some live tennis. FINALLY!

There is the Serbian roar again - once again he has the break.
Not bad serving at all from Draper - but brilliant from Djokovic.

A crushing return from Djokovic silences Centre Court, until a loud scream from the Serb is heard and a fist pump. There's the break in the fourth and it's a long, long way back for Draper now.
Another chance for a break and Djokovic sends in a lob, but a spinning jumping effort from Draper sees off his second break point of the game.
But as soon as they go off the table, another one comes on. Third chance for Djokovic.

Break point saved in style and again applause from Djokovic for Draper
A face-first tumble from Draper and that takes Djokovic to break point, but Draper saves it at the net, using every part of his 6ft 3in frame to stretch out and reach a point-winning volley. Deuce.
Djokovic 4-6 6-1 6-2 1-1 Draper*
A backhand goes long from Draper and that's 30-30. This could be the beginning of the end if he can't hold on to his serve here.

John: Incredible service game from Djokovic there. 4 aces, hitting the service line with 3/4 serves. Machine.
