Aryna Sabalenka stunned defending champion and former world number one Karolina Pliskova to reach the semi-finals at Eastbourne.

Seventh-ranked Pliskova fell 6-3 2-6 7-6 (7-5) to the Belarusian at the Nature Valley International.

World number 45 Sabalenka trailed 1-4 in the final set but rallied, hitting a total of 40 winners to secure victory.

Top seed Caroline Wozniacki later progressed with a 6-4 6-3 victory over Australia’s Ashleigh Barty.

Wozniacki, the world number two, will play Angelique Kerber in the final four after the German beat Russia’s Daria Kasatkina 6-1 6-7 (3-7) 7-6 (7-3).

Pliskova of the Czech Republic struggled for consistency in the first set but recovered in the second, improving her first serve percentage to 83%.

She won four successive games in the decider but Sabalenka used her forehand to outmuscle Pliskova and claim her first victory over a top 10 player.

She will face Agnieszka Radwanska in the semi-finals, following the Pole’s 6-2 7-5 win over fifth seed Jelena Ostapenko of Latvia.

Radwanska, who won the Eastbourne title in 2008, has been on the sidelines since April with back and hip injuries.

“I took only three dresses with me – [I thought] it’s enough for sure,” she said afterwards.

“I thought maybe one or two matches at the most – especially as I’m unseeded.”

Elsewhere, Britain’s Katie Boulter beat American Jennifer Brady to reach the final of the Fuzion 100 Southsea Trophy.

World number 144 Boulter beat Brady – ranked 69 places above her – 6-3 6-3 to set up a meeting with Belgian second seed Kirsten Flipkens, a Wimbledon semi-finalist in 2013.
