The physio comes on again for Hercog.
But she doesn't seem to do much and the Slovenian is back up to serve.

Simon Bartle: This is a thumping good match
Ali Pericles: Coco Gauff at 15 having the mental strength to save match points and come from a break down to take the match to a decider. At age 15 I’d start to have a mental meltdown if I landed on a hotel in monopoly at family Christmas!

If you didn't see the end of the second set, or even if you did, watch this.
It's great.

Surely this will be many people's favourite Wimbledon comeback of all time if Gauff pulls it off.
A 15-year-old coming from a set down on Centre Court? Amazing.
And it's looking like it might happen as she holds to love.

There it is!
Another forehand long from Hercog and a break for Gauff.
The American is looking so strong now.

Oh my. Hercog completely mistimes her forehand and gives up another break point.

*Hercog 6-3 6-7 (7-9) 1-2 Gauff
Hercog brings Gauff to the net and the American is fast enough to get there. But she's a bit too fast and taps her forehand long. Back to deuce.

Hello... Gauff comes to the net and pops a backhand over. Break point.

*Hercog 6-3 6-7 (7-9) 1-2 Gauff
Gauff gets her first chance of this set as she hits a forehand winner to get to 15-15.
The 15-year-old hits a backhand long, but recovers with a winner on the same side. 30-30.
It's VERY hard to see how this match is going to go, but the momentum seems to be every so slightly in Gauff's favour currently.

Martina Navratilova
Nine-time Wimbledon singles champion on BBC TVThree years maximum, I would give it. That's 12 majors.
I would be surprised if Gauff doesn't win a major within the next three years.

Josh Wing: Coco Gauff showing signs of a huge tennis pro and an entertaining one too - just at the same age as my car. I'm sure her Wimbledon challenge is inspiring for young players out there - just what’s needed.
Luke Davies: Coco Gauff is only 15 years old! What maturity and strength she’s shown to get back into this match. A future Grand Slam Champion, hopefully this year!

15 years old and a heart of a Lion! Incredible mentality.

Seems like everyone is getting caught up in this Gauff hype. She's only still in it because the nerves got to Hercog. The crowd are like sheep following what's hot.
