Here's the numbers from that second set...

All those hours in training, this is where Boulter hope it kicks in and you go on auto-pilot.
If you over-think it, it is horrible.

Halep 6-2 2-0 Nara*
Simona Halep is slapping the ball around freely, picking her spot on a sparsely filled Centre Court now.
Saying that, the world number one slips a backhand long by the narrowest of margins, double faults and then follows up with her first ace of the match.
She holds. That's six games in a row for Halep.
*Boulter 6-4 5-6 Cepede Royg
Katie Boulter shakes her arm out, trying to stop it tightening up before helping a forehand over the tramlines.

Halep 6-2 0-0 Nara*
Kurumi Nara has some serious zip around the court, but just can't convert regularly enough against the world number one.

40-40...
