It seems like Francesca Jones is having a lot of dialogue with her coach. I don't know whether that is a tactical thing to sort of change things as the match has gone on.
She has to find a way to not give cheap points away here, after gifting a bit of momentum back to Eva Lys.
*Jones 0-6 4-5 Lys
Talk about a response.
Eva Lys holds in double quick time and just as soon as Fran Jones lifted herself, she is back under pressure again.
The Brit is serving to stay in this one.

It's such a shame, these are the type of games that are an opportunity. I feel the momentum was going with Billy and he's just handed it straight back.

This is where the experience of Felix Auger-Aliassime is just shining through. He takes the hold to 15 with brilliant composure and now has the chance to take the set out of the hands of Billy Harris.
The Brit will be so disappointed with that. It was in his hands and there for the taking.
Jones 0-6 4-4 Lys*
Great composure from Fran Jones.
She sends a superb second serve to Eva Lys and the German can't return it as the Brit holds and keeps herself in it.

Billy Harris goes out there and gives it his absolute all. He feels like it's a second opportunity and he's playing with freedom, but its not all about freedom, he has to pay tactically smart too because Felix is an extremely good player.
The fact that he's been able to get into the match and get a break should give him confidence.
Felix will feel like he should be winning but Billy is a great ball striker and very physical about the way he plays, I think he can last the distance this match.

A few nerves creeping in from Billy Harris as he tries to serve out the set and put himself on level terms with 25th seed Felix Auger-Aliassime.
The Canadian drives into the net and his crunching forehand brings up two break points.

Eva Lys has lost a little bit of rhythm. It looks like she has got into a situation where she sort of feels like she is just going to make it through this match and she is just decelerating a little bit.
That's what is making the double faults creep in here.
*Jones 0-6 3-4 Lys
Eva Lys starts her service game with an excellent passing shot as Fran Jones tries to close the net.
The German holds to love and the pressure is back on the Jones serve to stay in this one.
*Harris 4-6 5-4 Auger-Aliassime
It sounds like Billy Harris has got his own little fan club on Court 17 as a bunch of spectators start up a "let's go Billy, let's go!" chant.
*Harris 4-6 5-4 Auger-Aliassime
Felix Auger-Aliassime finds three first serves and a forehand winner to take the hold and force Billy Harris to serve out the set.
Jones 0-6 3-3 Lys*
Just as we approach the hour mark in this match, Fran Jones has held her serve for the first time.
An excellent forehand gets her to 40-15 and it's a simple task from there as the Brit keeps herself in it.

Another Billy Harris service game passes Felix Auger-Aliassime by.
The Canadian has made 15 unforced errors in this second set while Billy Harris has barely put a foot wrong with two.
The 25th seed will have to serve to stay in this set.
*Jones 0-6 2-3 Lys

It's a shame but Francesca Jones just doesn't seem to move well enough into that backhand corner to get herself out of trouble.
There have been a lot of unforced errors coming out when Eva Lys has been able to pepper her on that backhand side today.

Finally a hold for Eva Lys in this second set.
She edges ahead despite a double-fault that brought the game to deuce.
This next service game feels huge for Fran Jones.
Jones 0-6 2-2 Lys*
Well, well, well.
Fran Jones lost her racquet halfway through her service game as it flew out of her hand as she went to return.
It costs her the point and she loses the game.
Lys converting her second break point to make it five breaks out of five on the Jones serve.

A bit of scrambling and harrying and Felix Auger-Aliassime has another hold on the board.
He has to start making inroads on the Billy Harris serve if he wants to get back into this set, though.
Harris 4-6 4-2 Auger-Aliassime*
Disappointment as Felix Auger-Aliassime returns Billy Harris' second serve poorly.
A couple of loose forehands from the Brit allow the 25th seed an opportunity but Harris holds his nerve to creep ahead once again.

Fran Jones gets herself 30-15 ahead against the serve but two mistakes allow her opponent back in.
The Brit is able to force deuce and an excellent forehand brings her a second break point of the contest.
Lys double-faults and Jones has regained the lead here.
Can she now hold her serve?
