Johanna Konta is through to the Wimbledon quarter-finals following a 4-6 6-2 6-4 victory over sixth seed Petra Kvitova.

Konta, from Eastbourne, found herself up against it after losing the first set 6-4 to Kvitova in a fierce-hitting clash on Centre Court.

The British number one did well to stay with Kvitova during the first few games as she struck winner after winner but the Czech produced strong serving to save two break points at 4-4 and a forehand wide from Konta sealed things in the next game.

Konta began turning the match around right at the start of the second set with a first break of the Kvitova serve.

She then held for 2-0 after a long service game and the errors began to leak badly from the Kvitova racket.

Konta missed a first set point at 5-1 and then took a medical time-out to have her left ankle strapped before serving out the set 6-2.

Konta had the bit between her teeth and, after Kvitova held in the opening game of the decider, the British player won five games in a row to take her to the brink of victory.

Kvitova forced Konta to serve it out, and a tense game brought two match points but four break points, the last of which the Czech took.

When Konta stepped up to serve for it again at 5-4, Centre Court was alive with tension, but the 19th seed took her third match point for a 4-6 6-2 6-4 victory.
