Britain's Katie Boulter has been knocked out by Daria Kasatkina 6-1, 6-4 in the first round of the Australian Open in one hour and 11 minutes.
There were high hopes for Boulter who beat highly-rated American Coco Gauff in three sets at the Gippsland Trophy last week, but it took just 23 minutes for Kasatkina to win the opening set against the 23-year-old, taking it 6-1.
Boulter was broken again by the impressive Russian in the second set as she went 3-1 up.

At 5-2 down on Boulter's serve, the Brit did incredibly well to hang on and saved four match points before following up with a break to make it 5-4. But it was then that Kasatkina broke Boulter again to win the contest on her fifth match point.
