Second seed Sorana Cirstea breezed through the first round of the Istanbul Cup on Tuesday as US Open champion Emma Raducanu prepares for her bow in the Porsche Tennis Grand Prix.

The Belgian – top seed once again in Istanbul – gets her campaign underway against Sweden's Rebecca Peterson on Wednesday.
Elsewhere, there were wins for seeds Veronika Kudermetova and Jil Teichmann, though Tereza Martincova is out after a surprise 6-4 7-5 loss to qualifier Anna Bondar.
World number 12 Raducanu meanwhile is also poised to get her latest tilt for silverware underway in Stuttgart in midweek, with the eighth seed facing qualifier Storm Sanders.
The title is up for grabs on the WTA Tour following Ash Barty's retirement, with her world number one successor Iga Swiatek a potential quarter-finalist for the Briton if she gets that far.

Seventh seed Ons Jabeur, meanwhile, fought back to beat Marketa Vondrousova 4-6 6-2 6-3, while qualifier Eva Lys overcame Viktorija Golubic 5-7 7-5 7-5 to set up a second round clash with Swiatek.
