Jack Draper's mother has performed a U-turn on attending his US Open clash with Jannik Sinner tonight.

The 22-year-old locks horns with the Italian needing just two victories to win the first Grand Slam title of his career.

Draper has been the big success story of the competition so far, with the Briton yet to drop a single set amid his charge to the last four.

Earlier this week, the tennis star's mother, Nicky, said that she 'probably' wouldn't be attending his semi-final clash with Sinner.

“It’s in the back of my mind," she told the BBC when asked if she was jetting out to the Big Apple.

"But I’ve been watching every match with my dad, with my dog, swearing and cursing, jumping up and down, clapping, having a glass of wine at the same time.

"I’ve got both of my boys out there, I think they’re doing fine without me. So probably not.”

However, speaking on Thursday, she then confirmed that she would be watching the action unfold.

“I’ve got a flight booked this evening," she said.

“I only decided this morning to go.”

Nicky has also shed light on Draper's friendship with tonight's opponent.

The duo played doubles together just a month ago but will need to put their fondness for each other side when they do battle at the Arthur Ashe Stadium.

Discussing their relationship, she said: "I think they're quite good friends actually.

“They’ve played some doubles and they’ve shared the odd dinner together.

"I think Jannik has made Jack some pasta and taught him how to cook pasta.

"They’re young boys, aren’t they?"

Should Draper win, he'll become the third Briton to play in the final of the US Open this century.

Andy Murray was the first, with the 37-year-old facing Novak Djokovic in 2012.

He ended up being too strong for the Serb on that occasion, with Murray beating Djokovic in a five-set thriller to secure his first career major.

Three years ago, Emma Raducanu defied the odds to make the final of the US Open.

She crushed Leylah Fernandez in the final, with many tipping her to dominate the sport for many years to come.

Yet Raducanu has struggled in the time since, with the 21-year-old crashing out of the tournament in the first round last Wednesday.
