    We'll be back tomorrow for Rafael Nadal's match with Nikoloz Basilashvili and Serena Williams' clash with Kaia Kanepi.

    See you then!

  2. Today's top stories

    Wimbledon champion Angelique Kerber was beaten 3-6 6-3 6-3 by Slovakian 29th seed Dominika Cibulkova in the third round of the US Open in New York.

    Madison Keys, runner-up to Sloane Stephens last year, recovered from a set down to reach the last 16, beating Serbia's Aleksandra Krunic 4-6 6-1 6-2.

    Another high-ranked departure was French sixth seed Caroline Garcia, conqueror of Britain's Johanna Konta in round one, who lost 5-7 6-4 7-6 (7-4) to Carla Suarez-Navarro - Sharapova's next opponent.

    German veteran Philipp Kohlschreiber produced one of the shocks of this year's US Open men's competition with a 6-7 (1-7) 6-4 6-1 6-3 win over fourth seed Alexander Zverev in the third round.

    Elsewhere, Australian John Millman, 29, will play five-time Roger Federer after reaching a Grand Slam fourth round for the first time with a 6-4 4-6 6-1 6-3 win over Mikhail Kukushkin of Kazakhstan.

  3. In case you missed it...

    .

    Roger Federer says a stretching forehand winner around the net post that left opponent Nick Kyrgios open-mouthed in disbelief ranks as one of the greatest shots of his career.

    The 37-year-old Swiss somehow reached a drop-shot from Kyrgios to flick it past the incredulous Australian on his way to a three-set win in the US Open third round.

    The 20-time Grand Slam champion was already in control, leading two sets to love, when he produced the shot on advantage point for Kyrgios at 3-3.

    "I definitely think it was a special one, no doubt about it," said the second seed, who won 6-4 6-1 7-5.

    "In practice you'd run into a fence!"

    More on that here.

  4. 'There is always a tougher opponent'

    Sharapova 6-3 6-2 Ostapenko

    Maria Sharapova: "There is no doubt that I feed off this energy. When I come out here you want to give everything you have. It is so inspiring hearing this crowd.

    "I have been on this tour for many years but every time I walk out here it feels like my first. I just wanted to play my best tennis.

    "Jelena is a phenomenal player. She is a Grand Slam champion so I can't expect an easy match.

    "I came out here and I wanted to do it and I did. I faced a tough opponent and I came through but there is always a tougher opponent in the next round.

    On playing Carla Suarez Navarro: "I will be facing a lot of spin. She is one of the best top spin backhanders on the tour. She is a challenge. I have lost to her before and she will be coming in as the underdog but I am ready."

  6. Game, set and match

    Sharapova 6-3 6-2 Ostapenko

    A 23rd straight victory for Maria Sharapova in the night session at the US Open.

    There wasn't much Ostapenko could do today.

  7. Match point

    Sharapova 6-3 5-2 Ostapenko*

    Wide serve forces Sharapova to drag her forehand. 15-0.

    Then another unforced error from Ostapenko draws Sharapova level. 15-15.

    A big serve takes it to 30-15 but Sharapova smashes back with a sublime forehand return. 30-30.

    And match point arrives as another thumping forehand fizzes into the corner.

  8. Sharapova holds

    Sharapova 6-3 5-2 Ostapenko*

    More aggressive play from Sharapova forces Ostapenko out wide and her forehand doesn't reach the net.

    And Ostapenko's backhand goes long - though a challenge is needed to prove it. 40-0.

    Another double fault from Sharapova. 40-15. Then a complete miss hit as the ball hits the outside of the racket.

    But no bother, a big serve seals the deal. Game Sharapova.

  9. Sharapova breaks

    *Sharapova 6-3 4-2 Ostapenko

    Ostapenko saves one... but then a double fault gives Sharapova the hold and break of serve.

  10. Two break points

    Sharapova 6-3 3-2 Ostapenko*

    And in no time it's two break points to Sharapova.

  11. Post update

    47% first serve success rate for Sharapova and only 43% for Ostapenko. That may explain a lack of service holds...

  12. Sharapova holds

    Sharapova 6-3 3-2 Ostapenko*

    Ostapenko smashes a terrific forehand down the line and into space but Sharapova responds with another angled ace to take the lead. 30-15.

    Then a wide backhand from Ostapenko and a fizzing second serve from Sharapova gives her the hold.

    A muted celebration from the Russian but I think I spotted a clinched fist on her walk back to her seat...

  13. Sharapova breaks

    *Sharapova 6-3 2-2 Ostapenko

    A fourth straight break as Sharapova delivers another blow.

    Can anyone hold serve?!

  14. Break point

    Sharapova 6-3 1-2 Ostapenko*

    Great defence from Sharapova. She changes direction of the ball, hitting strokes with depth and pace to push Ostapenko back behind the baseline. 30-15.

    And a superb rally ends with Ostapenko's fist thumping the air as Sharapova's streched backhand sinks into the net. 30-30.

    But it's break point to Sharapova again.

  15. Post update

    Sharapova 6-3 1-2 Ostapenko*

    Three breaks of serve in the opening three games.

    And a few more unforced errors and double faults from Sharapova.

    Interesting...

  16. Ostapenko breaks back

    Sharapova 6-3 1-2 Ostapenko*

    Ace from Sharapova. One break point saved.

    Then a sliced miss-hit from Ostapenko. Deuce.

    Sharapova reaches two sensational shots with the tip of her racket before Ostapenko eventually sinks the point. Advantage.

    And a double fault. Ostapenko with another break.

  17. Two break points

    *Sharapova 6-3 1-1 Ostapenko

    A fine return from Ostapenko takes the paint off the back line but it's called out. She challenges and it's in but she has to replay the point.

    Ostapenko doesn't let it bother her though, as she comes pounding back with a flying forehand down the line. 30-0.

    And she thinks she's got a break point but Sharapova's ace is called in and is proven right on Ostapenko's unsuccessful challenge. 30-15.

    But Sharapova hits into the net to gift Ostapenko two break points.

  18. Sharapova breaks back

    *Sharapova 6-3 1-1 Ostapenko

    Ostapenko is falling away from her toss and it's affecting her serves. Another one flies into the net but Sharapova doesn't make the most of the second serve, flashing it into the net.

    Two break points are saved but Sharapova delivers the blow with a thumping backhand down the line.

  19. Three break points

    Sharapova 6-3 0-1 Ostapenko*

    Once again Sharapova fights back with aggressive ground strokes. She's 30-0 up and Ostapenko shrugs her shoulders in despair.

    Another unforced error and it's three break points for Sharapova.

  20. Ostapenko breaks

    Sharapova 6-3 0-1 Ostapenko*

    Double fault.

    Break for Ostapenko! Clean slate it is!
