Italian Jasmine Paolini is into the Wimbledon quarter-finals after a tearful Madison Keys retired with an injury in the deciding set.
The American, 29, was forced to stop with the score locked at 6-3 6-7 (6-8) 5-5 on Court One.
Keys appeared to pick up the injury when serving for victory at 5-2 in the final set.
She took a medical timeout at the change of ends when leading 5-4 and was treated before leaving the court.
The 12th seed reappeared with strapping high on her thigh and was clearly hampered by the injury.
