US Open champion Emma Raducanu is refusing to be downcast after her defeat to Aliaksandra Sasnovich, insisting that she is focused on "the bigger picture".

The 18-year-old's 10-match winning run came to an abrupt halt at the Indian Wells Open – just her fifth tour-level event – as Sasnovich won in straight sets.

Sasnovich is ranked 100th in the world, but the 27-year-old has 16 career victories over opponents in the top 20, with Raducanu ranking 17th, and six over those in the top 10.

Raducanu cites the experience gap between herself and Sasnovich as a major factor in her defeat and believes that the loss can be taken as a positive lesson.

"I'm still very, very new to the tour," Raducanu said. "I think that experience just comes from playing week in, week out and experiencing all these different things. I'm kind of glad that what happened today happened, so I can learn and take it as a lesson so going forward I'll just have more experienced banked.

"[Sasnovich's] been on tour, probably been 4-2 down like hundreds of times whereas I've been 4-2 up... it's my third WTA tournament this year. [Experience] will come in time. Just got to not rush it and keep going and get my head back to the drawing board really.

"I didn't go in there putting any pressure on myself because in my mind I'm so inexperienced that I'm just taking it all in. You're going to have highs, and you're always going to have some lows where you're disappointed with how you performed.

"Aliaksandra played an extremely great match. You could tell she's more experienced than me. She went out there and executed her game plan better than I did. She deserved to win that.

"I think it's going to take me time to adjust, really, to what's going on. For the bigger picture, I'll be thanking this moment. That's the lesson I think, that you can easily get sucked into being so focused on the result and getting disappointed."

Raducanu is set to take part at the Transylvania Open that starts on October 25, as well as the Kremlin Cup in Moscow.
