Long from Alize Cornet! Bianca Andreescu just upped the power on those groundstrokes a little in that exchange to fend off the break point. Good depth too. But another backhand leaks into the tramlines.

Break point number two for the Frenchwoman.

Bianca Andreescu comes forward on to a backhand in mid-court but wraps it into the tape and then Alize Cornet hustles her way to deuce. And the now the 31-year-old has break point after her opponent drags a backhand well wide...

Slip for Andreescu as she tries to get any grass or left over dust out of the pimples of the shoes.

The rain we've had over the past few days means there is still plenty of juice on the turf.

Good serving from Alize Cornet to recover from 0-30 down, sweeping through four points to hold.

Punchy stuff from the fifth seed, leaping all over the Alize Cornet serve and following up with a ripping forehand from inside the service box. Bianca Andreescu shows she can mix it up too, disguising another forehand perfectly and opting instead for a deft drop shot.

The Canadian frames the next long and then rattles the tape with a backhand. 30-30.

It's a bit grey and chilly in SW19 today - Carol says the weather will get better later in the week - and Bianca Andreescu has kept her long sleeve top on at the start of this one.

There's nothing cold about the Canadian's backhand, striding into a big winner and holding to love.

Alize Cornet gets her serve working and holds serve with a well-made drop volley from close range, lovely touch as that was dipping awkwardly for the Frenchwoman. All square in the opening set.

We're under way, and this one is already shaping up to be an intriguing affair as Alize Cornet takes Bianca Andreescu to deuce before the fifth seed edges to a hold to get off the mark.

Things have not been straightforward for Bianca Andreescu since claiming her maiden Grand Slam title two years, with a knee injury forcing the Canadian to miss the three majors played last year.

But the 21-year-old is back to fitness and has eyes on becoming number one...

"Developing mentally, physically, emotionally, spiritually - all of that is really important to me," Andreescu told the Metro., external "On the court, I want to become number one in the world. I don’t know if that’s pushing it for this year, maybe top-three and then go from there.

"I think I’ve learned a lot from the physical problems I’ve had over the past couple of years.

"I don’t like to say that I’m injury prone. For sure, other players haven’t got as hurt as me, maybe - especially at my age - but I think that comes from overtraining, not scheduling things properly, not having the right fitness camp… A bunch of things."

Kicking off our coverage will be fifth seed Bianca Andreescu's meeting with France's Alize Cornet.

The 21-year-old Canadian, who won the US Open in 2019, has never progressed beyond the first round at Wimbledon and comes up against the 31-year-old Cornet on court two.

It is not unusual for grass courts to be slippery, but when they are under cover for longer, conditions become more humid, which in turn makes the grass more damp.

Pat Cash, who won Wimbledon in 1987, described players as looking like "Bambi on ice" as they tried to navigate the slippery areas.

"Grass courts are slippy and that is the challenge of playing on them," he said on 'Today at Wimbledon'.

"They have three different phases - very slippery, slippery on the outside and then towards the end of the tournament we get dust. It makes it really tricky."

After a slip on the famous grass court forced Serena Williams to retire injured within an hour of Roger Federer advancing when his opponent Adrian Mannarino also pulled out following a fall, the spotlight is on the conditions.

World number one Novak Djokovic said he did not recall "falling this many times on court" after several tumbles in his opener against Britain's Jack Draper on Monday, while Andy Murray says it is "extremely slippy out there".

Federer suggested it was "more slippery under the roof", which was on for much of Tuesday's play and some of Monday's while rain fell at SW19.

"You do have to move very, very carefully out there," Federer said.

"I do think it feels a tad more slippery maybe under the roof. I don't know if it's just a gut feeling."

Grass surfaces are always tricky to play on and adapting to the 'virgin' surface - as Novak Djokovic called it the other day - is part of the challenge at Wimbledon.

From close up on Centre Court, the surface looks very lush.

Combined with the precipitation in the air, and the greenhouse effect created by the roof being shut throughout most of the opening two days, it appears to have contributed to a more treacherous surface than usual.

Within an hour of Serena Williams hobbling off in tears, the Centre Court sprinklers were put on and water sprayed over the grass - including behind the two baselines.

The surface was then covered by a green protective tent before the roof was opened for the night.

It goes without saying Wimbledon's experienced ground staff know what they are doing and they regularly ask for feedback from the players.

Head groundsman Neil Stubley once said worrying about the surfaces gave him sleepless nights.

There has been a lot of debate about the surfaces at Wimbledon this year after both Serena Williams and Adrian Mannarino retired injured on Centre Court following slips. So what is making the grass so slippery?
