In the midst of a brilliant season, world number one Iga Swiatek had another milestone to celebrate on Thursday when she beat Gabriela Lee at the Poland Open.

Swiatek's 6-3 6-2 win against her Romanian opponent was her 48th of the season, already equalling the best tally reached by a female player in the entirety of 2021.

The top seed will have a chance to go one better than Anett Kontaveit and Ons Jabeur from last season when she faces Caroline Garcia in the quarter-finals of her home tournament.

Garcia beat Elisabetta Cocciaretto 6-3 7-5, while Jasmine Paolini dug deep to see off Clara Burel 6-1 6-7 (1-7) 6-0.

There was a big upset at the Prague Open, as defending champion Barbora Krejcikova was eliminated in a 3-6 7-5 (7-5) 6-3 defeat at the hands of Nao Hibino.

Fellow Czech Lucie Havlickova was dispatched in straight sets by top seed Kontaveit, but Linda Noskova will keep the home flag flying after beating Alize Cornet.

Noskova's first career tour-level quarter-final will come against Krejcikova's conqueror Hibino.
