It was a day for comebacks at the Stuttgart Open, with number one seed Iga Swiatek recovering from a set down to beat Karolina Pliskova in the quarter-finals.

Swiatek made a disastrous start, going 4-0 down, and though she broke back once, was unable to find the second as Pliskova took the opening frame 6-4.

The determined Pole stepped up a level though to take the second 6-1, before breaking early in the third.

It was still an improvement for the Czech player, who lost 6-0 6-0 to Swiatek in their only previous meeting in Rome in 2021.

Pliskova kept her opponent honest on her own serve, but Swiatek had too much for the world number 17 as she clinched the decider 6-2.

Aryna Sabalenka also showcased her powers of recovery as she beat Paula Badosa despite going a set down.

The second seed won 4-6 6-4 6-4 in an even contest that saw nine breaks of serve, before the Belarusian eventually got over the line.

Sabalenka is now the player with the joint-most comeback wins over the last two seasons (13) level with Caroline Garcia, though the French star was actually the victim of a comeback herself on Friday.

Garcia won the first set against Anastasia Potapova, before the Russian came back to take it 4-6 6-3 6-3 to set up a semi against Sabalenka.

There was no need for such drama from Ons Jabeur, who eased to a 6-3 6-0 victory against Beatriz Haddad Maia in just 68 minutes to confirm a clash with Swiatek.
