*Konta 2-3 Jabeur
Thwack. And there's your first ace. A speedy line-tickler from Ons Jabeur, who accelerates to another love-hold.

*Konta 2-3 Jabeur
Thwack. And there's your first ace. A speedy line-tickler from Ons Jabeur, who accelerates to another love-hold.
Konta 2-2 Jabeur*
Neat from Jabeur, hurrying in to meet a Konta drop shot and lobbing it agonisingly out of the Brit's reach. Despite that, Konta edges to a more comfortable hold.
*Konta 1-2 Jabeur
Johanna Konta is sent scuttling across court after a vicious forehand return and can only clip one into the roots of the net.
The 12th seed levels up and then opts for a net dart, forcing Ons Jabeur to go long.
30-15.

Anyone else wondering what the 1573 Arena is named after? Good.
Turns out it is a Chinese baijiu liquor. I'd be surprised if they sell that in your local 'Spoons.
*Konta 1-2 Jabeur
Looking pretty feisty on serve so far, Ons Jabeur. She took the opening game to love and drops just a single point in her second service game.

BBC Sport at Melbourne Park
Not the sort of conditions - or opponent - that Johanna Konta would choose for her first-round match.
Konta plays a methodical game as she looks to go through her "processes".
Jabeur, who beat her at Eastbourne last summer, likes to play with variety and that could disrupt Konta.
As could the slightly blustery conditions out on 1573 Arena...
Konta 1-1 Jabeur*
Ons Jabeur rattles a leaping backhand into the tape and Johanna Konta successfully holds having faced break point.
*Konta 0-1 Jabeur
Saved by Johanna Konta, finding the first serve she needed. Deuce.
*Konta 0-1 Jabeur
A slower second serve from Konta that kicks like a horse to throw Jabeur off, but the British number one hasn't got her eye in yet and jabs another baseline stroke long.
Break point Jabeur.
*Konta 0-1 Jabeur
Ons Jabeur makes it five straight points to open this match before tugging a forehand wide as Johanna Konta gets on the board for the first time.
A sloppy Konta forehand drifts long on the next point. 15-30.
*Konta 0-1 Jabeur
Johanna Konta has faced Ons Jabeur just once before, when she suffered a defeat by the Tunisian in Eastbourne last year.
The 25-year-old is making her fourth appearance in the Australian Open main draw, but is yet to progress beyond the first round.
Konta's best run in the tournament saw her reach the semi-finals in 2016.
*Konta 0-1 Jabeur
Nice change up from Ons Jabeur, pinning Johanna Konta deep before dropping in a well-weighted slice to get the British number one scampering. She holds to love.
Konta 0-0 Jabeur*
And here we go...
Ones Jabeur will serve first.

Not one of the best views from the media seats you'll find at Melbourne Park.
Although there would be few complaints about the sun canopy if it was 35C and sharp, skin-piercing Melbourne rays...
And it is better than the standing-only spot, a few of the British press pack had while watching Dan Evans yesterday on a packed court 14.
Konta v Jabeur
Johanna Konta comes into 2020's opening Grand Slam having only played one match since September's US Open.
The 28-year-old is continuing to manage a knee injury- a tendonitis-like inflammation - which she suffered in the latter stages of last season.
She did not play again in 2019 after losing to Ukrainian Elina Svitolina in the New York quarter-finals, making her return in Brisbane last week with a three-set defeat by Czech Barbora Strycova.
"Having played only one tournament in the past four months, I'm really happy to be back in the swing of things," Konta, who reached the Melbourne last four in 2016, told BBC Sport.
"Overall, I think practice is going well. I feel I am continuously building and getting better."
Konta v Jabeur
Yes, Johanna Konta is one of six British players set to feature on day two of the Australian Open after the opening day's play was ruined by heavy rain.
Konta was meant to play Tunisian world number 78 Ons Jabeur but it was one of the 32 matches not completed in Melbourne on Monday.
Kyle Edmund will also resume against Serb Dusan Lajovic with a 5-2 lead.
Fellow Britons Katie Boulter, Heather Watson, Harriet Dart and Cameron Norrie also hope to play as planned.
Konta v Jabeur
It's like raaaaaaain, on the opening day...
But, luckily for tennis fans, it seems to have cleared up meaning there 96 matches scheduled for day two at Melbourne Park.
And British number one Johanna Konta is up first.
