Laura Robson beaten by Kirsten Flipkens at the Miami Open

Great Britain's Laura Robson is out of the Miami Open after losing her first round match to Kirsten Flipkens of Belgium.

Robson is on the comeback trail after struggling with wrist injuries and is playing on a protected ranking at the moment.

And she could not get past the World No 65 Flipkens, who eventually prevailed 7-6 6-2 after just over an hour and a half.

The first set was tight and both players broke serve twice, before Flipkens won the tie-break 7-4.

However, the second set was more one-sided, Flipkens breaking twice more while Robson failed to convert five break point chances of her own.

But, as at Indian Wells last week, Robson again showed signs of promise, as she looks to get her career back on track.

There were also defeats for all three of the British players involved in the qualifying tournament, with Katie Swan's run ended by Samantha Crawford.

The 16-year-old Swan, who is originally from Bristol but is based in the United States, posted a career-best win over world No 102 Lauren Davis in the opening round of qualifying.

That set up a clash with 109th-ranked Crawford for a place in the main draw, but it was the American who came through 6-2 4-6 6-2.

Swan, ranked 521st, gave another hugely encouraging performance but was affected by a thigh problem in the deciding set and lost the last four games.

The teenager became Britain's youngest ever Fed Cup player when she made her debut last month, turning professional a week later.

Naomi Broady lost 6-4 6-2 to Belarus' Aliaksandra Sasnovich while in the men's tournament, James Ward fell 6-3 6-3 to American Bjorn Fratangelo.
