Johanna Konta has been forced to retire from the Madrid Open because of an unexpected upper respiratory illness.
The Eastbourne-based British #1 was competing in the event and was trailing her 1st Round encounter against France’s Caroline Garcia.
But the 24-year-old was experiencing troubles with her breathing on the clay court and after receiving medical attention opted to end her interest in Spain.
Garcia was gifted a route to the 2nd Round with a 6-4 2-1 retired success.
And former British #1 Laura Robson, who used her protected world ranking of #58 to enter the main draw, also bowed out of the tournament at the first hurdle.
World #5 Victoria Azarenka, the Belarussian who is on a resurgent spree this season, proved too hot to hand and gave Robson a tennis lesson in finishing with a commanding 6-4 6-2 victory in 84 minutes.
But 22-year-old Robson managed to save five match points in their first ever meeting on the WTA Tour.
Former world #1 Azarenka, a recent champion at Indian Wells and Miami, made it 25 wins in 26 matches by dismissing Robson.
