Vcitoria Azarenka pulls out late at Miami Masters

World number three Victoria Azarenka pulled out of the Miami Masters shortly before her second-round match today.

The two-time champion of the Florida event was due to take on American wildcard Madison Keys but withdrew because of a right ankle injury.

Lauren Davies of the US took her place in the draw.

It is the same injury that caused Azarenka to withdraw before her quarter-final at Indian Wells a week ago.
