- Pole first to reach last 16 25 times in a row at WTA events
- Jack Draper out in second round against Jakub Mensik
Iga Swiatek continued to build momentum and confidence at the Miami Open as she reached the fourth round with a hard-fought 7-6 (2), 6-1 victory against the veteran Belgian Elise Mertens, the 27th seed.
Throughout an extremely tight opening set, Mertens demonstrated her intelligence and resourcefulness as she made life difficult for the second seed. In the tie-break, however, Swiatek rose to the occasion and then played a brilliant final set to seal the victory.
