Fans told ITV News Emma Raducanu should not be discouraged as ITV News Correspondent Robert Moore said her defeat 'won't be judged too harshly'
Raducanu, 18, suffered a disappointing 6-2 6-4 loss to Belarusian player Aliaksandra Sasnovich in the second round in Indian Wells.
The Brit was visibly frustarted early on - and Sasnovich quickly took control. In under 90 minutes, she lost the match.
It has been 27 days since the British teen stunned the world with her US Open triumph. She has since enjoyed the highs of star-studded red-carpet events.
But it was just Raducanu's third WTA Tour tournament and she said she was not going to beat herself up at the loss.
She said: “I think it’s going to take me time to adjust really to what’s going on. I mean, I’m still so new to everything.
“Like the experiences that I’m going through right now, even though I might not feel 100% amazing right now, I know they’re for the greater good.
“For the bigger picture, I’ll be thanking this moment. So, that’s the lesson I think, that you can easily get sucked into being so focused on the result and getting disappointed.
“I mean, I’m 18 years old. I need to cut myself some slack.
“I’m still very, very new to the tour. I think that experience just comes from playing week in, week out and experiencing all these different things.”
Sasnovich will continue to a third-round match with former world number one Simona Halep.
Romanian player Halep seeded 11th, beat Marta Kostyuk 7-6 (2) 6-1.
Meanwhile, former world number one Andy Murray beat Adrian Mannarino 6-3, 6-2 in his first match as a wild-card.
