Canadian teenager Leylah Fernandez (14/1 US Open outright) stunned Angelique Kerber to reach the quarter-finals of the US Open.

On the even of her 19th birthday, Fernandez produced the performance of her career to send the 2016 US Open champion packing.

After eliminating Naomi Osaka, Fernandez continued her stunning run and recorded a 4-6 7-6 (7-5) 6-2 victory over Germany’s Kerber on Sunday night.

Fernandez’s reward is a match against fifth seed Elina Svitolina, and she says she is enjoying the journey as she tries to book her place in the semi-finals.

Fernandez told reporters: “I was just glad I was having fun on the court. I have been working hard since the day I started playing tennis and the day I set my mind to being a professional.

“I expected that one day my tennis game is going to come through and that I’m going to be on the big stage in front of a big crowd and getting the wins.”

Elsewhere, second seed Aryna Sabalenka overcame ten double faults to battle past her former doubles partner Elise Mertens 6-4 6-1. She will now face Barbora Krejcikova after the Czech beat Garbine Muguruza 6-3 7-6 (7-4).

There was also a shock in the men’s draw as Spanish teenager Carlos Alcaraz came back from behind to beat German Peter Gojowczyk in five sets and reach his first Grand Slam quarter-final.

Alcaraz recorded a 5-7 6-1 5-7 6-2 6-0 win, and he became the youngest player in the Open era to reach the US Open men’s last eight. He will now face Canadian Felix Auger-Aliassime next in New York.

Earlier in the day, Russian Daniil Medvedev outclassed British number one Dan Evans to reach the last eight. Evans lost 6-3 6-4 6-3 to the 2019 runner-up, and he conceded he “got a good, healthy lesson”.

On Monday, British teen Emma Raducanu will face home favourite Shelby Rogers in the last 16. Raducanu has yet to drop a set in New York, but Rogers should push her all the way, having stunned top seed Ashleigh Barty over the weekend (Rogers 6/5, Raducanu 4/6 – Match Result).

Alexander Zverev tackles Jannik Sinner, while Novak Djokovic (4/5 US Open outright) is expected to advance as he prepares to face Jenson Brooksby of the USA.
