Ace from Karolina Pliskova, a challenge from Harriet Dart as she looks to cling on, but that's caught the line.

Set point.

Pliskova takes control of the tie-break, popping a couple of unreturnable ground strokes Dart's way. Two mini-breaks for the Czech.

Solid serving from Karolina Pliskova to edge into a 2-1 lead in the tie-break.

A touch of nervous tension surrounding Court 12 now...

This shows how Dart really stuck with Pliskova on the scoreboard which is important. You can see the nerves of Pliskova.

She's putting in less than half of her first serves, not a typical performance from the ace machine. She's a little off.

There have been a few aces and a few double faults by both players in the first set of the Dart v Pliskova match.

Here are some tips from her the Czech seed's sister Kristyna on how to improve your serve...

...and can Harriet follow her victory over Krystina at Eastbourne by beating Karolina as well?

Take a deep breath, find some composure... Harriet Dart finds herself fighting to hold serve at 30-40.

Great resilience from the 21-year-old, she turns it around to advantage and then sizzles a forehand down the line, but Karolina Pliskova meets it and Dart cracks the tape. Deuce.

Another meaty serve from the Brit sets up a winner, and she nonchalantly fires in an ace to hold. Lovely stuff.

It's business as usual on Court Two.

Marin Cilic has nabbed an early break against Yoshitiho Nishioka, who earlier sent a shanked forehand flying out of the court and down on to the spectators outside.

Cilic is in good form at the minute, having beating Novak Djokovic to claim the title at Queen's a week ago.

What do you know Jo?

The British number one was all smiles as she walked past chatting away with her coaching team after Monday's practice.

Restrictions means there is no photo of Jo from the court she was on, but we all know what she looks like.

Konta's first hurdle is in the guise of Russia's Natalia Vikhlyantseva - that's on Tuesday at 11:30 BST.

By the way, it's roasting at the Aorangi. The breeze helps, but it's tough work out there on the practice courts.

A lethargic Pliskova backhand drops long, and Harriet Dart breaks back!

The crowd on Court 12 love that from the British wild card.

Harriet Dart is leading Karolina Pliskova 3-2 on aces, and the Czech has just thrown down back-to-back double faults.

Chance to break back for the Brit... she pushes Pliskova around court and slings in a winner for 0-40. That's three break back points.

Karolina Pliskova punches long and follows up with a wayward backhand.

Harriet Dart holds on, but needs to break the seventh seed's serve if she is to not lose this opening set.

Harriet Dart finds herself serving to stay in the first set.

The British wildcard scrambles to 30-15, and then forces Karolina Pliskova's return into the tramlines with a punchy, middling serve.

No chance of getting to that passing backhand winner though... deuce.

Dart has worked hard through the juniors and challenger series where you could end up losing money just from expenses. She has traveled to Egypt , Kazakhstan, that has been her life.

There is no doubt Wimbledon's courts are looking lush but the "ordinary" grass on Henman Hill has the odd hay-like patch.

There are only so many weeks of hot weather that we can have before we start wondering about hosepipe bans...

But it seems we won't be seeing watering cans instead of sprinklers here.

"If there was a hosepipe ban that was about to be imminent then we would have been given the heads-up a few weeks ago, just so we can get our contingency plans in line," Neil Stubley, head of courts and horticulture, told BBC Sport.

"As it stands at the moment I don’t think we will be seeing a hosepipe ban during these Championships."

Phew.
