Britain's Emma Raducanu says an encouraging Wimbledon run has "fuelled the fire" to continue her upward trajectory over the rest of the season.

Raducanu, 21, was beaten 6-2 5-7 6-2 by New Zealand qualifier Lulu Sun in the fourth round on Sunday.

It was a disappointing exit after a series of dominant performances had heightened excitement at the All England Club.

But, having reached the fourth round of a major for the first time since winning the 2021 US Open, Raducanu reflected positively on the past week.

"I feel good about things going forwards. I feel optimistic," said Raducanu, who is set to move back inside the world's top 100 next week.

"As bitter as it is to take, I think [this defeat] happened for a reason.

"You don't want things to happen too easily and too quickly. I had that before. I don't necessarily want just a massive spike."

Raducanu, who was given a wildcard for the All England Club, was outplayed for much of a fascinating contest.

Having won six matches in a row on the SW19 grass, Sun oozed confidence and hit a flurry of winners.

Raducanu wrestled back momentum by winning the second set but lost serve early in the decider shortly after needing treatment following a fall.

The opening game of the third set was stopped and she received treatment - on her leg and back - while laid out on the court.

Having missed last year's Wimbledon after having operations on both wrists and her ankle, she added: "Six months ago when I was starting out after surgery, I would have signed for the fourth round at Wimbledon.

"Of course I'm disappointed. Of course I want more.

"It fuels the fire and makes me more hungry."
