Hello and welcome to LIVE updates of the US Open 2021 quarter final clash between No.5 seed Elina Svitolina and Canadian teen sensation Leylah Fernandez. The players are due out on court at Arthur Ashe Stadium soon.

GAME, SET AND MATCH! - FERNANDEZ 6-3 3-6 7-6 SVITOLINA. Wow! The 19-year-old is into the semi finals. She wins a topsy-turvy decisive tie break by a 7-5 scoreline and edges out the No.5 seed in two hours and 24 minutes. She will now meet No.2 seed Aryna Sabalenka or No.8 seed Barbora Krejcikova in the last four.

TIE-BREAK LATEST – Fernandez leads 4-2 - Fernandez strikes first with a crunching return winner up the line to punish another weak second serve. Svitolina then shanks a horrific backhand way off court but gets a lifeline when Leylah blasts a forehand into the tramlines.

FERNANDEZ 6-3 3-6 6-6 SVITOLINA. Svitolina survives another double fault for 30-30 and wriggles through to take us into a tie-break decider.

FERNANDEZ 6-3 3-6 6-5 SVITOLINA. Both players are refusing to fold here. Svitolina bites back from 40-15 down to make deuce and then absorbs constant pressure under a barrage of thunderbolts from Leylah. The Canadian keeps letting rip and gets her reward with a backhand winner. The 19-year-old is one game away once again.

FERNANDEZ 6-3 3-6 5-5 SVITOLINA. Some of the rallies in this match have been irresistible. Svitolina edges the hold to level matters with a sublime drop volley after the players had the crowd gasping with more baseline brilliance. The Ukrainian had been 30-0 up but needed to hang tough at 30-30 and is now back in business after being 5-2 down.

BREAK! - FERNANDEZ 6-3 3-6 5-4 SVITOLINA. Elina’s not done yet! The Olympic bronze medallist digs in at 30-30, raising the volume of her grunts and upping the power on her groundstrokes. She lures the backhand error long to clock up break back point and fizzes home a drive volley to deny the young Canadian on this occasion.

FERNANDEZ 6-3 3-6 5-3 SVITOLINA. Superb. Svitolina nails back-to-back aces down the T pose the serve-out question after Fernandez had made 30-30 with a supreme forehand up the line.

FERNANDEZ 6-3 3-6 5-2 SVITOLINA. This time the teen sensation – who only turned 19 yesterday – consolidates to 30. Svitolina sees the drop shot coming a mile away at 40-30 and thinks she’s going to blaze a winner to make deuce. Fernandez gets there and the Ukrainian can only block a volley wide. It’s a let off for Leylah but she won’t care. She’s one game away from securing a late birthday present for herself – a spot in the last four of the US Open.

BREAK! - FERNANDEZ 6-3 3-6 4-2 SVITOLINA. More jubilant raising of a teenage arm and it can only mean one thing – the Canadian underdog takes control again. Svitolina leaves herself too much to do at triple break point down. She fends off one but a bullet forehand penetrates her defence and we have a third break in a row!

BREAK! - FERNANDEZ 6-3 3-6 3-2 SVITOLINA. Have that! Fernandez can’t back it up as an error long coughs up two break back points. The Canadian saves one with a first ace of the match but Svitolina pounces on a poor second serve with a venomous crosscourt return. Still anyone’s match.

BREAK! - FERNANDEZ 6-3 3-6 3-1 SVITOLINA. A huge reaction from Leylah – she’s seriously pumped up out there! She almost plays herself at times in that game, mixing winners with near misses. In the end she strikes first blood in this set. A fizzing return winner up the line to punish a timid serve earns her the BP and she snares the game in style when she comes out on top in the exchange of volleys that follow a surprise drop shot.

FERNANDEZ 6-3 3-6 2-1 SVITOLINA. A third double fault of the match has the crowd murmuring anxiously for the 19-year-old as she falls 0-30 down. She responds with a big first serve but then gets slightly fortunate when Svitolina picks the wrong way with a pass and allows her to volley a winner. The Ukrainian digs in to force deuce but a fabulous drive volley taken out of the sky finds the postage stamp and the world No.73 is soon walking to her chair and raising her hands in the air to ask for more love and energy from the crowd.

FERNANDEZ 6-3 3-6 1-1 SVITOLINA. Elina gets away with that. The No.5 seed is pressed at 30-30 and should be serving from deuce, but Leylah misjudges a hopeful retrieval and ends up losing a face-off at the net.

FERNANDEZ 6-3 3-6 1-0 SVITOLINA. That’s an important riposte from the teenager. She looks frustrated at 0-30 but battens down the hatches to reel off four points in a row and seize that scoreboard advantage at the start of the decider.

SET! - FERNANDEZ 6-3 3-6 SVITOLINA. Fernandez finds some magic on her return game and ends up earning three separate break points. She looks in charge on the third but a stonking crosscourt pass on the run from Svitolina catches her out. The Ukrainian nails a big forehand and then conjures up an ace to fend off the challenge and level the match!

FERNANDEZ 6-3 3-5 SVITOLINA. There’s still a way to go but Leylah is doing her best to make this interesting. A crosscourt forehand pass shows she’s got some swagger back and she easily holds despite chucking down a second double fault of the match. Svitolina now has a second chance to serve out the set.
