There's been a lot of different body language on both sides of the court in this game.
You can tell Jack Draper knows it's important to get this service hold...
*Draper 6-4 4-3 Gomez
Nervy moments for Jack Draper on his second serve but he manages to keep his cool to take us to deuce.
He earns game point but a loose forehand sends us back to deuce.
*Draper 6-4 4-3 Gomez
Wow. A serious wobble on serve for Jack Draper as he hits three double faults in one game to hand Federico Gomez a break point.

The sixth seed's 13th double fault of the day gives Zarazua three set points - and the Mexican needs just one, with a well-constructed point clinching the second set and taking us into a decider.
*Draper 6-4 4-3 Gomez
Federico Gomez responds with a very impressive hold to love of his own.
Jack Draper two games from taking a two-set lead.

Ever been back to the same bar/pub on the lunchtime after a raucous night before?
I'm sure you have. Come on, admit it. No judgement here.
Anyway... the point being, there is that feeling of returning to the scene of the drama here on Louis Armstrong Stadium.
This is where Daniil Medevdev was carrying on last night in that chaotic encounter against Benjamin Bonzi.
Security has been beefed up at the entrance to the photographers' pit to ensure no sleepy snapper wanders onto the court today...
Draper 6-4 4-2 Gomez*
Jack Draper holds serve without fuss.
No blemishes on his record in that one as he retains that break of serve lead.

Renata Zarazua is a fighter, that's for sure.
Madison Keys is just trying to find her way around the court and playing in front of your home fans is always nerve-wracking, so I think that's making things a little tougher to close out.

Another glorious passing forehand winner down the line by Federico Gomez. This time it seals the game and he keeps the deficit to just the one break.
Draper 6-4 3-1 Gomez*
That's a lovely passing forehand to work Federico Gomez to game point but the frustrations are beginning to show as another error once again takes us to deuce.
Gomez will be desperate to win this game, a double break at this point would go a long way to deciding this set.

So far so good for Draper.
Given he hasn't played since 3 July, the British number one will be happy with his level.
His first serves have been slightly slower than usual - around an average of 111mph in the opening set - but he's finding plenty of them.
The forehand is cooking nicely, too. Some explosive winners on that wing have been greeted by 'ooohs' from the Armstrong crowd.
*Keys 7-6 (12-10) 6-6 Zarazua
One of the best points of the match ends with Madison Keys missing a forehand after some brilliant scrambling defence by Renata Zarazua.
We're into another tie-break.
Draper 6-4 3-1 Gomez*
Federico Gomez does all the hard work to save the break point and work his way to game point but sends us back to deuce with a daft forehand.
Draper 6-4 3-1 Gomez*
Nicely done by Federico Gomez, wiping out both break points with some composed hitting.
But oh no, he hands Jack Draper a third opportunity when he hits a double fault.
Draper 6-4 3-1 Gomez*
Jack Draper is grinding through the gears now.
He brings up a couple of break points on the Federico Gomez serve.

Once again, this match takes a sharp swing as Madison Keys fights back, pumping her first and shouting "come on!" as she breaks Renata Zarazua with a powerful forehand winner.
Then for the second service game in a row, she serves two double faults but still manages to hold, and with the match ticking over the two-hour mark, Zarazua must hold serve to stay in the match.
Draper 6-4 3-1 Gomez*
Bit of a tricky service game for Jack Draper to consolidate that break but he passes the test and seals the hold when Federico Gomez fires into the net.
*Draper 6-4 2-1 Gomez
Ha, a colleague and I were just discussing Jack Draper's new kit.
What are everyone's thoughts?

Jack Draper's outfit is really nice. I like the colours, it is different.
Honestly, the sleeveless look is really going to help him. It hasn't been too humid yet but their shirts are sticking to them out there, so it must be pretty humid today.

There it is.
This time Jack Draper strikes early in the set and he takes the break of serve to add to his one-set lead.
