  1. Tie-break

    Kvitova 6-6 Collins

    Both players yell, for different reasons as Kvitova smacks across a great winner. Mini break.

    2-1.

  2. Tie-break

    Kvitova 6-6 Collins

    1-0 - no mini breaks on the Kvitova serve.

    1-1 - the Czech player returns wide.

  3. Jonathan Jurejko
    BBC Sport at Melbourne Park

    After that flurry of break points in consecutive games in the fifth and sixth, neither player could wrestle another off their opponent. Which means one thing...

    Collins won 32% of receiving points in the regular set, Kvitova won 24%. But Collins has a woefully low first-serve percentage...

  4. *Kvitova 6-6 Collins

    A love game.

    Tie-break.

    That was coming to be fair.

  5. Skupski bageled

    It's bagel-time for Neal Skupski in his mixed doubles semi-final - unfortunately the Brit and his many-named Spanish partner Maria Jose Martinez Sanchez were on the receiving end.

    Barbora Krejcikova and Rajeev Ram took the opening set 6-0 on Margaret Court Arena.

  6. Kvitova 6-5 Collins*

    Collins comes out on top in the longest rally of the match - 17 shots.

    Mini fist pump from the American.

    15-0.

    A very good serve brings up 30-0.

  7. Kvitova 6-5 Collins*

    Yet another mistake from Kvitova.

    Deuce.

    But in this topsy turvy match, the 26-time WTA Tour winner produces a fantastic winner before Collins returns into the net.

    Game Kvitova.

    Can she now break?

  8. *Kvitova 5-5 Collins

    Good serve and volleying from Kvitova brings up 40-15.

    But this game ain't over yet as the Czech player once again makes an error with a shot that fails to creep over the net.

    40-30.

  9. *Kvitova 5-5 Collins

    It all seems a bit quiet, like the old Highbury.

    15-15.

    Lights on. And they are bright enough to ensure those wearing prescription sunnies can keep them on indoors...

  11. *Kvitova 5-5 Collins

    Another poor return - a 17th unforced error - earns Collins game point which she takes as Kvitova makes another error with a sliced backhand.

  12. Kvitova 5-4 Collins*

    30-0.

    But then Collins double faults - her third - she was serving so well earlier in the match.

    30-15.

  13. Kvitova 5-4 Collins*

    Petra KvitovaEPA

    She gets a little lucky on the next point and apologises for it.

    No apology for the next point as Kvitova charges to the net and forces an error from Collins.

    The American then yells out that yell of frustration as she misjudges a shot.

    We've all been there, Danielle.

    Kvitova holds.

  14. *Kvitova 4-4 Collins

    Kvitova loses a challenge - the ball was out, says the computer.

    She wins the next though :)

    15-15.

    Kvitova looks undecided whether to come into the net or not and pays for her indecision as Collins spanks a forehand past her.

    15-30.

    Five minutes! The Laver roof closes about the same time as I'd imagine it takes to fry an egg on the street outside...

  17. THE ROOF HAS CLOSED

    *Kvitova 4-4 Collins

  18. Skupski trails in mixed doubles semi

    While the roof closes on Rod Laver, Briton Neal Skupski is in the early stages of his mixed doubles semi-final alongside Spanish partner Maria Jose Martinez Sanchez.

    They are taking on Czech Barbora Krejcikova USA's Rajeev Ram and it's not started well for the Anglo-Spanish combo - they trail 4-0 in the first set.

    Both players hide under the dugout-style roof hanging over their chairs. Time to take some liquids on board...

    The crowd are, meanwhile, being entertained by YMCA. I can't see anyone standing up and doing the dance. Too hot for that sort of behaviour.

  20. *Kvitova 4-4 Collins

    They've just shown a shot of a spectator who has wrapped his head in newspaper.

    It must be hot.
