I think we need to see a bit more energy from Edmund and hear a bit from him too.

Uh oh. The first mini-break goes the way of Seppi.

It brings up set point.

A trademark clench of the fist from Edmund.

He gets his nose back in front but again Seppi is strong behind his own serve. Two quick points to the Italian.

The players head to their chair level in the breaker. Both of their levels have dropped a little in these last couple of points. A few errors are creeping in. Pressure?

Seppi is so good at using Edmund's pace and redirecting the ball. He's causing him a lot of problems.

Two more points exchanged by either player. Edmund is once again the aggressor but pushes it a little too much. The backhand goes wide.

Lovely from Seppi. He guesses right and is there waiting for an Edmund forehand. He then whips the ball beyond the Briton.

Edmund responds with a serve-forehand one-two combo.

All square.

Edmund survives. A very rare unforced error from Seppi hands the Briton the game. Into a tie-break we go.

Two mistakes from Edmund. 15-30.

"Come on Kyle," shouts a man in the crowd.

Seppi is two points away from the opening set.

Time is called and Edmund is again going to have to serve to stay in the set. He gets a supportive clap from his Swedish coach Fredrik Rosengren.

This looks to be the same issue Kyle Edmund had in the previous round. The trainer comes out on court and begins digging his thumbs firmly into the Briton's shoulder for a massage.

Edmund doesn't look too concerned but not ideal by any means.

Maybe Kyle is feeling a bit of pressure because he knows this is a good opportunity to reach the quarter-finals.

Maybe he can hussle through this set and then relax a bit and start playing his shots rather than relying on his serve.

He's showing very little emotion on court but Andreas Seppi is powering through these service games. Once again he races into a 40-0 lead before dropping a rare point. No bother for the Italian. He clinches his sixth game at the second attempt.

Worryingly Edmund has called for the physio.

Kyle is not firing on all cylinders yet but if the adrenaline kicks in you feel he can start to take control, His serve is keeping him in it at the moment.

Excellent, excellent stuff from 0-30 down on his serve by Edmund. An ace helps him close out the final two points. He's looked really strong on the big points under pressure. Now he needs to find a way to halt Seppi's serene progress on serve.

Ace. Edmund wrestles back to 15-30.

Now the net cord helps him to 30-30. Seppi is wrong-footed as the ball takes a clip of the tape.

Still work to do for Edmund though.

Wayward from Edmund. A forehand into the tramlines and then a backhand into the net.

The pressure mounts on the Briton. 0-30.

Seppi is looking worryingly strong for British tennis fans. After that lengthy previous game the Italian races through on his own serve with two winners and an ace.

The pressure is back on Edmund's shoulders. He's going to have to serve to stay in the set in a mo after a little breather.

Well that game got the crowd going, especially a small knot of blue-shirted Italian fans in one corner - best not mention the World Cup. It didn’t quite match the 20-minute game Edmund played two days ago, but it was another tense mini contest that the Briton has come through.

Great serving, Kyle. When he needed it there the serve came to his rescue, three or four times on a break point and then another ace to help him finally close out the 10-minute game.

A vital hold.
