Barty, who had strapping on her left thigh, left the court for a medical timeout before eventually retiring midway through the second set with the scores level at 2-2, citing a hip injury.
The Australian arrived at Roland Garros with the injury but managed to make her way through her first-round match on Tuesday despite needing treatment on her left hip. Afterward, she admitted that she was “not quite 100%”.
Having arrived to Thursday’s game with her left leg strapped, her serve seemed hampered early on, and after saving some three early break points to level the scores at 1-1, Barty lost five straight games to lose the first set in 36 minutes.
She received treatment off the court, but could not continue for much longer, walking to the net and shaking hands with Linette after the fourth game of the second set.
World no. 45 Linette progresses to the third round in Paris for the first time since 2017 where she will face Tunisian Ons Jabeur.
