IT was a bit of a mixed bag of results across the WTA Tour’s two grass court events yesterday, with two seeds making their way through in each of the Viking Classic and Bett1Open quarter finals, whilst in the other two matches the underdog prevailed. In Berlin, fifth seed Belinda Bencic advanced through to the final four with a hard-fought three-set win over Russian Ekaterina Alexandrova 6-4 4-6 7-6, needing two hours and 31 minutes to dismiss her opponent.
The Swiss star will now face Frenchwoman Alize Cornet who stunned Grand Slam winner and sixth seed Garbine Muguruza in an epic contest, winning in a third set tiebreaker, 7-5. The overall match saw Cornet come from behind to post a 4-6 6-3 7-6 win over the Spanish seed in two hours and 40 minutes to claim her spot in the final four. Cornet won 76.6 per cent of his first serve points and broke twice from her two chances, whilst rallied hard against a solid Muguruza who broke twice form four chances, and won 67.9 and 70 per cent of her first and second serve points.
“It was a long match with a lot of emotion, especially in the tiebreak,” Cornet said post-match. “I can’t believe I made it at the end. She’s a champion, she never gives up. I should have gone for a it a bit more, I was waiting for a mistake and I was a bit tight – it’s normal. But I was very resilient too, I was always behind in the score in the third set but I kept grinding, I kept fighting to the end and it’s a really nice victory.
“I had a really tough clay season, I couldn’t play well and I don’t know why – but to play well on grass, it’s unexpected but beautiful.”
