09:50 CET - Keep your eyes peeled as we'll have a fresh new tracker later today, looking ahead to more thrilling action in Miami!
04:40 CET - Due to how late the Pegula - Raducanu match went, the tournament organisers decided to move Novak Djokovic's game against Sebastian Korda to Thursday. That match will occur at 15:00 local time (20:00 CET).
04:20 CET - Number four seed Jessica Pegula was given all she could handle in her fourth round win over Emma Raducanu. The American advanced 6-4, 6-7(3), 6-2 in two hours and 18 minutes. Pegula served well in the match, getting in 78% of her first serves. She also converted four of her nine break opportunities, which played its part in her moving on.
01:25 CET - Grigor Dimitrov battles back from a set down to get the better of Francisco Cerundolo 6-7(6), 6-4, 7-6(3). Winning 80% of his first serve points, Dimitrov broke Cerundolo's serve once in each set. In the end, the Bulgarian raised his level in the final set tiebreak, allowing him to advance.
22:16 CET - Arthur Fils has claimed a seriously impressive win in Miami, battling back from a set down to defeat No. 1 seed Alexander Zverev, 3-6, 6-3, 6-4.
It was a really great showing from Fils, who has now reached back-to-back Masters 1000 quarter-finals. But for Zverev, more disappointment, as he still is unable to find his best since losing in the Australian Open final.
19:50 CET - Absolutely astonishing scenes at Miami, as wildcard and world No. 140 Alexandra Eala has dumped out world No. 2 and five-time Grand Slam champion Iga Swiatek, 6-2, 7-5.
Eala's truly miraculous week has continued, with the Filipino having beaten three major champions on her way to the semi-finals. The 19-year-old teenage talent was superb in the first set and showed great steel in the second to produce a historic upset.
A really disappointing result for Swiatek, however, who was erratic and shaky throughout. The Pole held serve just twice in the match, and her forehand was all over the place. She continues to struggle for her best form.
18:10 CET - Play is now underway in Miami!
16:00 CET - Good afternoon and welcome to our coverage of today's tennis at the Miami Open!
Play gets underway in a little over two hours, with second seed Iga Swiatek facing 19-year-old surprise package Alexandra Eala, who has beaten the likes of Madison Keys and Jelena Ostapenko en route to the last eight.
The final women's quarter-final clash sees fourth seed Jessica Pegula take on Emma Raducanu in a blockbuster tussle. That match is due to begin a little later at 00:00 CET.
Meanwhile, on the men's side of the tournament, Novak Djokovic faces the challenge of Sebastian Korda and Grigor Dimitrov comes up against the in-form Francisco Cerundolo.
There's also one fourth-round match to be played following yesterday's rain delay, and it's an intriguing one: Alexander Zverev vs Arthur Fils. That clash is due to get underway around 20:00 CET.
