It is incredible to see how Navarro constructs these points.
I don't think she has a problem being forward, behind, ahead. She just plays one point at a time.
It's Coco Gauff who has much more to lose.

Gauff still doesn’t look like she’s settled out here. She looks anxious. She needs to fire herself up and get herself going.

The embarrassment!
A wild Coco Gauff mishit flies up into the rafters of Centre Court before making its way back down towards the front row of fans.
One guy has his eyes on the prize and has both hands ready to receive it, but he can't hold onto the ball and it bounces out onto the floor, earning a laugh from the rest of the crowd.
It didn't seem to put Emma Navarro off, though. What a set from her.

Navarro just looks likes she has time on the ball here and I am sure that the time she had on Centre Court (against Naomi Osaka) will have done her the world of good.
