Keothavong exits US Open
Great Britain's Anne Keothavong could offer little resistance as she lost to sixth seed Angelique Kerber in the first round of the US Open.
It was a tough draw for the Londoner against a player who has rocketed up the rankings in the last year and Kerber was far too strong, winning 6-2 6-0.
The German was ranked outside the top 100 last summer before a surprise run to the semi-finals at Flushing Meadows, and she has not looked back, winning two titles this year and reaching the last four at Wimbledon.
Keothavong began brightly, trading well with her opponent off the ground, and she even had a break point in the first game, which Kerber saved.
The British number two held serve twice but, once she dropped serve for the first time in the sixth game with a poor drop shot, the floodgates opened.
Kerber did not lose another game, racing through to the second round - where she is likely to face Venus Williams - in only 54 minutes.
Keothavong was philosophical afterwards and admitted her confidence is low.
She said: "It was probably one of the toughest first-round draws I could have had. She's full of confidence. She's won more matches than anyone else this year and I haven't.
"The first couple of games I felt like I was there with her. She's someone I've played against quite a few times. We had a really good match indoors in Copenhagen this year.
"Where we both are in terms of confidence and our games I think reflected the outcome of the match today. I just made too many errors and she's someone who doesn't miss much."
