Good evening and welcome to our live coverage of The Big One: Britain's Emma Raducanu takes on Leylah Fernandez in the FINAL of the 2021 US Open and it could hardly be more exciting...

The champion reacts:

That winning moment

What a meteoric rise for Emma. She will move up to 23 in the world on Monday and will become the British No.1. Incredible.

GAME, SET AND MATCH! - RADUCANU 6-4 6-3 FERNANDEZ. The dream DOES become reality for the teenage qualifier. Britain’s 18-year-old Emma Raducanu wins the US Open on debut at Flushing Meadows and in just her second ever appearance in the main draw at a major. She serves it out on her third match point with an ace from deuce after saving two break points to cap a magnificent one hour and 51-minute battle.

She is the first British woman to win the US Open since Virginia Wade in 1968 and the first to lift a Grand Slam title since Wade’s Wimbledon triumph in 1977.

Raducanu is patched up and returns to court trailing 30-40 as she tries to serve out for the title...

Raducanu serves for the US Open title: The Kent teenager moves two points from victory at 30-15 but then comes unstuck as Leylah digs deep once more. A booming forehand earns her a break point and Emma cuts her leg sliding in the midst of the drama. A medical time-out is called for her to receive treatment. Fernandez isn’t happy… what a moment to stop!

RADUCANU 6-4 5-3 FERNANDEZ. What a hold! Fernandez refuses to go down just yet. She somehow survives two match points before unloading a brave and quite brilliant forehand winner up the line. A fantastic rally follows it with Emma first to blink. She will now serve for the title.

RADUCANU 6-4 5-2 FERNANDEZ. Nothing fazes this British teenager. What a star. She consolidates with aplomb and is now just one game away from becoming a Grand Slam champion!

BREAK! - RADUCANU 6-4 4-2 FERNANDEZ. That’s incredible anticipation – and it’s a break too! Raducanu sees Leylah charge to mid-court to surely belt away a forehand. The 18-year-old guesses right and with rapid reactions flashes a pass down the line to take the game. The fairytale is edging ever closer to reality for the GB starlet.

RADUCANU 6-4 3-2 FERNANDEZ. There’s a shared fist pump between coach and player as Raducanu finds a big serve down the T to keep Leylah at arm’s length and regain the scoreboard advantage.

BREAK! - RADUCANU 6-4 2-2 FERNANDEZ. Bang! Raducanu secures the instant break back. The Kent teenager follows up a supreme defensive lob with a sumptuous crosscourt backhand to earn the chance at 30-40 before rasping a return winner to halt Fernandez’s comeback bid from gaining greater traction.

BREAK! - RADUCANU 6-4 1-2 FERNANDEZ. This time Raducanu’s serve is the one placed under the spotlight as the world No.73 looks to build upon that recovery by snaring two break points of her own. The Brit storms back, saving both and earning game point but again Fernandez won’t let up. The Canadian earns a third with a crosscourt forehand winner and makes the breakthrough when Emma zaps a backhand into the net.

RADUCANU 6-4 1-1 FERNANDEZ. Wow. What a comeback from Leylah. A fifth double fault has a Fernandez-pro crowd murmuring anxiously and she’s soon facing triple break point when a miss-hit from Emma leads to a forehand error from the Canadian. It looks bleak given the momentum of the match but once more the 19-year-old shows her resilience with some brave crosscourt groundstrokes, a scintillating backhand up the line and a flurry of clutch serves as she reels off five points on the spin to get out of dodge.

RADUCANU 6-4 1-0 FERNANDEZ. In. The. Zone. Emma fires down her first ace, lands another big serve and finishes off a highly confident hold to 15 with her 13th winner of the match via a sharp forehand.
