In a New York minute, everything changed for US Open champion Raducanu

Instead she's walking away with $2.5 million in prize money, with a host of endorsements likely on the way, as she earned the acclaim from the British royal family and fellow sports stars with her celebrity-making achievement.

She is - for now, at least - unaware of the jubilation that awaits her back home, telling reporters she had not checked her phone.

"I have absolutely no idea what's going on outside of the little world that we're in here. We've just been in the quiet room, just enjoying the moment, taking it all in," said Raducanu.

"We just really need to just shut out from everything, just enjoy it as a team, because it was a team effort. I didn't get here by myself at all."
