Johanna Konta defeated Caroline Wozniacki 6-4 6-3 to win the Miami Open on Saturday – the biggest title won by a British woman in 40 years.

Konta, who had never won an elite WTA premier mandatory event, will move to No 7 in the world rankings with the victory.

She began superbly, breaking to love in the opening game, before Wozniacki swiftly broke back to level at 2-2.

After another break each, the Briton took advantage of two double faults from the Dane to break to 5-4 and serve out for the set.

There was a similar pattern to the start of the second set, with the pair exchanging breaks in the first two games.

The key moment came when Konta broke to go 4-3 up, with a little help from the net cord.

Konta then broke again, with a lob on match point, to secure the biggest win of her career and the best by a British woman since Virginia Wade won Wimbledon in 1977.
