  1. Raducanu breaks

    Zhang 2-6 0-3 Raducanu*

    What more can you say? This is wonderful tennis from Emma Raducanu.

    A forehand winner makes it 3-0 in the second set and the third round is within sight.

  2. Break point Raducanu

    *Zhang 2-6 0-2 Raducanu

    A fifth deuce. Raducanu keeps making the returns and Zhang is getting no free points.

    That's loose. Zhang tightens up and fires wide. It's a break point for a 3-0 lead to Raducanu.

  3. *Zhang 2-6 0-2 Raducanu

    A volley sets up break point for Raducanu, but Zhang puts away an ace to stay alive.

    A brilliant forehand moves Zhang within touching distance of a hold, only to be denied by another superb backhand from Raducanu.

  4. *Zhang 2-6 0-2 Raducanu

    It's a long way back for Zhang, who is yet to find a way of really disrupting Raducanu.

    The Chinese player has a chance to close the game out but Raducanu nails a two-handed backhand for deuce.

  5. Laura Robson
    Former British number one on BBC radio

    I sort of don't have anything to say - it's just been great!

    Every time Emma is under a little bit of pressure she just digs deep.

  6. Barty cruising against Tauson

    Barty 6-1 Tauson

    Over on Arthur Ashe Stadium top seed Ashleigh Barty is in action against another 18-year-old - Clara Tauson of Denmark - and the Australian is in full charge of proceedings.

    Tauson is the player who beat Raducanu in Chicago last month to deny the Briton her maiden WTA title.

  7. *Zhang 2-6 0-2 Raducanu

    Zhang fails to apply the pressure and Raducanu makes no mistakes.

    The US Open main draw debutant steps up to volley a forehand winner for 40-30 and an ace slams the door shut. Raducanu is in firm control here.

  8. Zhang 2-6 0-1 Raducanu*

    Raducanu is dominating in all aspects on court 10.

    Still, plenty can happen yet. The Briton nets and Zhang has half a chance at 15-30.

  9. Raducanu breaks

    Zhang 2-6 0-1 Raducanu*

    Zhang salvages deuce with a backhand and survives another break point soon after.

    A third chance for Raducanu...

    And that one is taken! This just keeps getting better from the 18-year-old.

  10. Break point Raducanu

    *Zhang 2-6 0-0 Raducanu

    It appears a much better start for Zhang after being broken to love in the opening game of the first set, but Raducanu isn't having any of it.

    The Briton fights back from 30-0 down to force break point.

  11. Russell Fuller
    Tennis commentator on BBC radio

    Emma smiled her way through that first set and it was virtually perfect. There were winners on the forehand and backhand side and she had only two unforced errors.

  12. *Zhang 2-6 0-0 Raducanu

    Will there be a response from Zhang here?

    Something needs to change quickly if the two-time Grand Slam quarter-finalist is to reach the third round.

    Zhang gets things under way in the second set.

  13. David Law
    Commentator on BBC radio

    That was quite an astonishing opening set. This is really something.

    Take your pick with any of the winners in that set and they would stand side by side with anyone else in the draw.

  14. Game and first set - Raducanu

    *Zhang 2-6 0-0 Raducanu

    No chance. A bullet forehand down the line sets up three set points.

    Raducanu only needs one. A mighty impressive display from the 18-year-old superstar.

  15. Raducanu serving for first set

    Zhang 2-5 Raducanu*

    This has been a blistering start by Emma Raducanu, and now she can make it count by closing out the first set.

    A couple of errors by Zhang and she's well on her way!

  16. Zhang 2-5 Raducanu*

    Zhang Shuai battles back, though.

    From two points down, the world number 49 digs in and Raducanu hits well wide to concede the game. 5-2.

  17. David Law
    Commentator on BBC radio

    This has got to be beyond what all of us expected against an opponent of this quality.

  18. *Zhang 1-5 Raducanu

    That just about sums up Emma Raducanu's game so far.

    An inch-perfect backhand clips the line for 0-15.

    Another unreachable backhand makes it 0-30. Two points to go.

  19. *Zhang 1-5 Raducanu

    There's certainly no sign Raducanu is slowing down anytime soon either.

    A booming forehand makes it 40-0, and after Zhang gets on the board the Chinese player nets and will now have to serve to stay in the opening set.

  20. Laura Robson
    Former British number one on BBC Radio 5 Live Sports Extra

    Wow! That's a good start isn't it? I thought it would be closer from their last match but coming out to go a double break up is another thing.

    She is flying around the court. Her movement has been fantastic.
