World number one Serena Williams of the USA
added another win to her Miami campaign after beating Ayumi Morita of
Japan 6-3,6-3 in the third round. Elder sister Venus withdrew from the
Sony Open with a lower back injury just
minutes before she was supposed to take the court against Sloane
Stephens. Venus Williams is third second big name on the women’s side to
pull out of the event, joining the two-time champion Victoria Azarenka
and former US Open champion Samantha Stosur.
