10 Biggest Prospects On The WTA Tour

10. Katie Swan

It is still early days for Great Britain's Katie Swan given that she only turned 17 towards the end of March but it is difficult not to get excited over her potential after her progression over recent months.

She has already represented Great Britain in the Fed Cup - becoming the youngest player to play for the nation in the competition - and she registered a massive upset victory over American Lauren Davis after being handed a wildcard to enter qualifying in Miami.

That win has moved Kansas-based Swan up to 463 in the WTA rankings but her position in the standings will not be of immediate concern as she looks to play with the freedom that is currently serving her well at the moment.

However, Swan has had to deal with expectation since the start of 2015 after she reached the Australian Open girls' final but it is a positive sign that so far, she is taking the extra attention in her stride.

The progression of Johanna Konta, Heather Watson and Naomi Broady can only help Swan, but she must continue along her own path if she is to join them on the main tour.
