Hello and welcome to LIVE updates of a big moment for GB’s Emma Raducanu. The teen starlet thought she was going to take on Australian Open finalist and No.13 seed Jennifer Brady until the American withdrew with a knee injury. That means the 18-year-old will meet Swiss lucky loser, Stefanie Voegele instead.

GAME, SET AND MATCH! – RADUCANU 6-2 6-3 VOEGELE. It’s rollercoaster finale as Emma sees six match points go begging and saves a BP before finally serving it out at the seventh time of asking to charge into round two with a straight sets win on debut in the US Open main draw. She was just too strong for the experienced Swiss player and prevails in one hour and 18 minutes.

BREAK! – RADUCANU 6-2 5-3 VOEGELE. Boom! Raducanu has the bit between her teeth and refuses to let go. Voegele thinks she’s done enough from deuce but not this time. Emma punches the air as she makes the breakthrough and will now serve for a spot in the second round.

RADUCANU 6-2 3-3 VOEGELE. That’s resilient work from the Swiss. She sees a 40-0 lead evaporate and is left scrapping hard from then on. Raducanu earns a BP from deuce but can’t convert. Voegele continues to dig deep and just about wriggles through to level.
