rewrite this title Six Kings Slam live: Sinner and Djokovic compete in big-money Saudi exhibition

Sinner clumps a net-cord but then leaves Tsitsipas rooted to the baseline with a drop shot.

It brings up break point and Tsitsipas goes long on the forehand, with Sinner once agani taking over the point behind his forehand.

The bounce off this court is ridiculous and the spin on Sinner’s wide serve takes the ball away from Tsitsipas.

Sinner has made an identical start to the second set as he did to the first. Tsitsipas is searching for ideas and changes his racket.

From 40-15 up on serve, Tsitsipas is broken. The Greek can only watch as a forehand from Sinner flies past him. Several errors from Tsitsipas then hand Sinner the break, as the Italian once again targeted the one-handed backhand.

Tsitsipas looks to be on a roll as he moves to 0-30 against the Sinner serve, but the Italian fires a forehand winner to take charge once more.

Sinner swats away a smash to bring up set point, where Sinner makes his first double-fault of the match. A powerful approach from Sinner quickly brings up a second chance.

And he takes it. Tsitsipas pushes a backhand wide, with Sinner once again targeting the Greek’s one-hander. Sinner wraps it up in 36 minutes, but it could have been even quicker after winning the first five games.

Fair play to Tsitsipas. He could have thrown in the towel after facing a bombardment from Sinner, but he gets his second game on the board by finding a forehand winner down the line. Trying to fight fire with fire.

A loose couple of points from Sinner and Tsitsipas finds a good return to bring up three break points.

Sinner saves the first couple but not the third! Tsitsipas raises his hands and has something to celebrate after getting on the board.

He launches himself into another massive forehand and then goes the right way as Tsitsipas pushes an approach down the line, returning it with a lovely backhand winner down the line.

Tsitsipas double faults on the break point and Sinner wins his fifth game in a row. He’s going to serve for a bagel-set, next.

Sinner is not messing around. The Italian holds to love as he lands a serve out wide and whips the forehand winner into the corner.

After the lack of effort from Zverev earlier, Sinner is looking absolutely locked in.

Emphatic from Sinner. He sets up another break point, with another winner.

The Tsitsipas backhand gets another battering, with Sinner then going very close to the line with the forehand winner. He gets the break.

Sinner is hitting 75 per cent of his shots to the Tsitsipas backhand. An onslaught.

This is relentless from Sinner, who is looking to bomb the Tsitsipas backhand as much as he can.

Tsitsipas double-faults on 30-30 but Sinner then can’t get the return in play with the chance to go a double-break up.

Sinner goes again and finds a lovely backhand winner down the line. Tsitsipas saves for the second time as he moves in and puts away the volley!
