Queenslander Ash Barty’s reign as world number one is set to come to an abrupt end on Monday.

After losing in the fourth round of Wimbledon last month, Barty lost 6-7 (5-7), 6-3, 6-4 to American Sofia Kenin in the Rogers Cup.

The shock result means she’ll relinquish her spot as the world’s best female player to either Naomi Osaka or Karolina Pliskova.
