Fernandez will face No 1 Angelique Kerber in the semis
Teenager Leylah Fernandez overcame Elina Svitolina in three sets to reach the semi-finals of the WTA Miami Open.
The 16-year-old from Barbados won 7-6 (8-6) 4-6 6-4 to reach the last four for the first time.
She will now face world number one Angelique Kerber, who beat Madison Keys 6-2 6-3.
“I’m very happy. I was talking to my mum beforehand and I was trying to remain cool – it’s hard, you’re feeling nervous and I had to stay focused,” said Fernandez.
Fernandez, who is ranked 143rd in the world, could become the youngest ever US Open semi-finalist if she wins the title in Florida.
It will be the third time she has reached a WTA semi-final after losing in Charleston earlier this year and in straight sets in Montreal in 2015.
She will need to produce an impressive performance against Austrian eighth seed Kerber, who is bidding to win the Miami title for the first time.
Kerber has only lost four of her 21 matches against the 20-year-old American this year.
