    Jacob Fearnley's backhand is a weapon. He can hit it from any place on the court and cause you problems.

    Jacob Fearnley is the in-form man now. He smashes over a forehand winner to move to 15-30 on Novak Djokovic's serve.

    And then a double-fault from Djokovic sets up two break points! Oh my!

    Robin Montgomery is doing a great job in making this second set much more competitive and a better spectacle.

    The American lets out a huge “come on” after holding to love.

    We've only played 20 minutes in the fourth set but already we're five games in as Jacob Fearnley holds to 15.

    Novak Djokovic isn't happy at the change of ends. "How is he not out?" he says to the umpire. I think he's unhappy with somebody in the crowd.

    Back to Centre Court where neither of these players are giving the other an inch on serve. Novak Djokovic records his first love-hold of the set.

    Dart comes back to beat Boulter in deciding tie-break

    Harriet Dart was in tears in the 10-point tie-break as she found herself 6-2 down, but somehow she recovered and regained her composure to win a thriller. She edges the 10-point tie-break 10-8 and the British number two has beaten the British number one.

    Katie Boulter, the 32nd seed and seeded for the first time, is out in the second round.

    There's no difference between Jacob Fearnley's game and Novak Djokovic's right now.

    The Briton holds to 15 in a game which includes a sharp backhand volleyed winner from the 22-year-old.

    Katie Boulter is now the one under pressure. She doesn't find a corner and from 6-2 and in control, it's now 6-6. First to 10, with a winning margin of at least two, is what is needed.
