Tennis correspondent on BBC Radio 5 Live Sports Extra
The crowd are stunned. They are now coming to life because Billie Jean King is on the big screen! There's about 10,000 people here. For all of Emma Raducanu's excellent, ruthlesness and coolness under pressure, this has been a pretty abject performance from Shelby Rogers.
11 straight games from Raducanu.
Wow.

There is murmuring around the crowd. Rogers is all at sea, and Raducanu is two games away from the quarter-finals.
Naomi Broady
British player on BBC Radio 5 Live Sports Extra
It's strange, isn't it, the difference in play from Rogers from the start of the match to now. It looks like she doesn't know what to do out there.
Rogers 2-6 0-4 Raducanu*
Double fault from Shelby Rogers. The American is really struggling out there in front of her home crowd.
*Rogers 2-6 0-3 Raducanu

The Raducanu express is flying.
Gigi Salmon
BBC Radio 5 Live tennis commentator
Nothing is going Shelby Rogers' way. She cannot stop the train that is Emma Raducanu.
*Rogers 2-6 0-3 Raducanu
18 unforced errors on the backhand by Rogers so far.
Naomi Broady
British player on BBC Radio 5 Live Sports Extra
I think seeing the other teenagers in the draw in Leylah Fernandez and Carlos Alcaraz inspires Raducanu and pushes her to do a bit more. To see other young players, a day ahead of her in the tournament, I wonder if seeing them does well gives her belief that she can do it too.
*Rogers 2-6 0-3 Raducanu
Rogers' forehand drops long.
Raducanu is a set and three games up.
Rogers 2-6 0-2 Raducanu*
And an ace.
Rogers 2-6 0-2 Raducanu*
No sweat. Back to 30-30. Nerves of steel from Emma Raducanu.
Rogers 2-6 0-2 Raducanu*
Better from Rogers who connects well on the volley then Raducanu skews a backhand well wide.
30-0 for the American.

Raducanu is just such a good frontrunner. She has yet to drop a set from qualifying.
Naomi Broady
British player on BBC Radio 5 Live Sports Extra
What's so impressive about Raducanu is when she gets ahead in the match, she stays very businesslike. She doesn't try and overthink or overplay. It is great mental control.

If you're Shelby Rogers, don't look up at your box - they look all at sea.
