Konta comes from behind to beat Halep

Great Britain's Johanna Konta fought back from the brink of defeat to secure a stunning upset victory over Simona Halep in the Miami Open quarter-finals on Wednesday.

Halep had a chance to serve for the match in the second set, but Konta broke and never looked back, eventually clinching a 3-6, 7-6 (9-7), 6-2 victory after a two-and-a-half-hour battle.

Things looked much better for the Romanian early in the match. A break in the fourth game was all she needed to close out the first set, and though Konta broke first in the second for a 3-0 lead, Halep hit back strongly with two more breaks to find herself serving for the match at 5-4.

But Konta wasn't done yet. With her back against the wall she conjured up three more break points, converting the third to get back on level terms and force a tie-break, which she duly won.

And, having swung the momentum her way, Konta did not let it slip. Further breaks in games five and seven of the deciding set saw her romp to a big win against the third seed.

Awaiting Konta in the semi-finals is the winner of the match between top seed Angelique Kerber and Venus Williams, set to take place later this evening.

Should she reach the final, she is projected to return to the Top 10 when the new WTA rankings are released on Monday.
