The return was so good and set Katie Boulter up well, but she pumps a forehand long.

She's got another chance, though.

A big backhand return down the line from Katie Boulter brings us to deuce.

Will: Whether GB can win or not rests entirely on Katie Boulters' shoulders. I expect Raducanu to win all her matches but if GB reach the final can Boulter beat Swiatek or Paolini? A tough ask. Maybe it will come down to beating either Swiatek or Paolini in doubles.

Katie Boulter will hope that Leylah Fernandez doesn't enjoy the same resurgence that Rebecca Marino enjoyed in the second set against Emma Raducanu earlier.
