Duckworth is showing variety and being entertaining. He's keeping Murray honest in this fourth set. It's still anyone's.

Feels like the atmosphere is a little more boisterous since the restart...
I presume those who didn't have a ticket at the start have filtered in.
One person shouts "I love you Andy!" as Murray is about to serve, bringing a classic side-eye from the Scot and no hint of a smile.
This is business, not pleasure.
Murray 4-6 6-3 6-2 3-3 Duckworth*
Aces aplenty for Murray as he holds on serve. Whether it is because the roof is closed and the sound is more contained or the spectators are just getting into things more, the atmosphere has moved up a level now with cheers and whoops with every point.

Some good shots from both players, Duckworth hitting a backhand volley at the net and Murray catching his opponent out with a backhand slice but Duckworth serves well to hold to 30.

Good serving once again from Murray as an 11th and 12th ace of the match ensures he holds comfortably.
*Murray 4-6 6-3 6-2 1-2 Duckworth
There's a good mix to Duckworth's shots again, the highlight of which is a backhand winner that is angled out of Murray's reach.
Duckworth then serves well to close out the game. An important hold.

That gave Duckworth time to regroup. He needed that and is looking to benefit from it. Murray has got to keep in attack mode.
*Murray 4-6 6-3 6-2 0-1 Duckworth
"Let's go Murray, let's go" echoes around a now enclosed Centre Court, the fans very much enjoying the new acoustics as Murray takes his first point to make it 15-15.
Duckworth is serving well, though, and takes the first game of this set. Just the start he needed.

Will that halt Murray's momentum? Or has it just delayed his victory?
We're under way in this fourth set.

The roof closes and the lights flick on, prompting a cheer from the fans.
Murray and Duckworth hit the ball to each other to warm up. Play gets back under way in two minutes.

Excited chatter and an energy building for the entertainment that's going to come.
Probably a queue for a beer in a plastic cup, too.
Got to be a cheer coming when the lights flash on and illuminate the stage.
