  1. *Ahn 6-7 (2-7) 0-2 Williams

    Former British Davis Cup player on BBC Radio 5 Live Sports Extra

    I think Serena prefers conditions a little quicker, not necessarily dry and dusty but where her serve can be effective. She's moving better now than she was. A damp, heavy clay court can be hard to move, that was the case for her early on.

  2. *Ahn 6-7 (2-7) 0-2 Williams

    Serena Williams races through her next game and this is beginning to look a very steep mountain for Kristie Ahn now.

    Ahn played well in the first set. That's the killer. Her serve wasn't punished too much, she was able to dictate some of the points and still didn't come out with the set.

  4. Williams breaks

    Ahn 6-7 (2-7) 0-1 Williams*

    How much has that 74-minute losing opening set taken out of the mind and body of Kristie Ahn?

    Serena breaks at the first available opportunity in the second set. From being a break down and her opponent serving for the set, to being a set and a break up. A very quick turnaround.

    Williams will be breathing a huge sigh of relief.

    Ahn 6-7 (2-7) Williams

    An ace to seal the first set and Serena Williams gets the job done after a mammoth, and entertaining, 74-minute first set.

  8. Four set points for Williams. This is going to be a good recovery from being 5-4 down with Ahn serving for the set.

  9. Ahn 6-6 Williams

    A sweeping forehand from Williams after an entertaining rally and that's 5-2. Two more points and the first set is hers.

  10. Ahn 6-6 Williams

    Naomi Cavaday
    BBC Radio 5 Live tennis commentator

    If Ahn can nick this set it will be interesting to see how Williams can respond. I've not seen much quality play, much aggressive play, from her.

  11. GB's Broady loses first set

    *Vesely 6-2 0-0 Broady

    Britain's Liam Broady has got some work to do on court 10, having lost the opening set to Czech Jiri Vesely.

    Qualifier Broady had saved a set point before succumbing when he shanked a forehand.

  12. Ahn 6-6 Williams

    Ahn pulls a forehand wide and Williams has a two-point advantage in this tie-break. 4-2.

  13. Ahn 6-6 Williams

    A clever backhand, with the pace reduced, from Williams and she's at 3-2.

  14. Ahn 6-6 Williams

    A great winner from Ahn who sends one into the right corner after her previous shot had been in the left corner. Williams, on the slide, can't get a racquet to it. 2-2.

  15. Ahn 6-6 Williams

    A Williams drop shot sits up nicely for Ahn and she sends it away. 2-1 Williams, first set tie-break.

  16. Williams with an early 2-0 lead in this first set tie-break.

  17. Ahn 6-6 Williams

    A forehand into the net from Williams and that means the first set will be settled via a tie-break. Ahn had served for the first set, but also had to serve to save it.

  18. USA! USA!

    McHale 6-2 6-4 Muchova

    Kristie Ahn versus Serena Williams is a match between two Americans and another one, Christina McHale, has had a good day as she has knocked out 22nd seed Karolina Muchova.

  19. *Ahn 5-6 Williams

    A hold to love for Williams. Her opponent was serving for the first set, now she's serving to save it.

  20. Ahn 5-5 Williams*

    David Law
    BBC Radio 5 Live Sports Extra tennis commentator

    This is so stressful for Serena Williams. I feel like it is an extreme version of what we saw with Andy Murray yesterday, someone battling age and raging against the end of their career - which is going to come. I find it captivating that she is trying to fight that.

    I can imagine her career flashing before her eyes and how good she expects to be. And when these balls don't go in, she struggles to handle that.
