Britain's Francesca Jones sobbed loudly on court as injury wrecked her hopes of a first main-draw win at the Australian Open.
Early retirements became a theme on day two in Melbourne, with men's eighth seed Felix Auger-Aliassime and qualifier Marina Stakusic - who was taken off court in a wheelchair - both forced to retire after cramping.
British number three Jones struggled to move from the early stages of her first-round match against Polish qualifier Linda Klimovicova on Monday.
The distraught 25-year-old valiantly tried to continue but ultimately quit when trailing 6-2 3-2.
A groin injury had forced Jones out of a match at last week's Auckland International, but it was a glute problem that led to her retirement against Klimovicova.
