Tennis by AFP 4th Jun 2021 5:14 AM Top seed Ashleigh Barty said it was heartbreaking to retire injured midway through the second set of her French Open second-round match against Poland s Magda Linette on Thursday. The Australian, who won the title on her last visit to Roland Garros in 2019, left the court for medical treatment after losing the first set 6-1. She had struggled with a hip problem during her first-round win over Bernarda Pera on Tuesday and called it quits at 2-2 in the second set on Court Philippe Chatrier on Thursday. Barty also retired injured from the Italian Open during her quarter-final against Coco Gauff last month.
