Victoria Azarenka and Sam Stosur will play out the final of the Qatar Open in Doha after both won their semi-finals on Saturday.  Azarenka won a dramatic semi-final as she overcame an injury to beat Agnieszka Radwanska, 6-2 6-4 in a somewhat more straightforward match than their previous encounters.  It was interesting to see Radwanska give a decidely cold handshake afterwards, which may have had something to do with Azarenka’s form after her supposed injury.  Sam Stosur won the other semi-final after just one set had played as Marion Bartoli retired with a calf injury.  Azarenka has won all her previous encounters with Stosur, but question marks will surround whether she is physically 100%… i’ll go for a Stosur shock to break Azarenka’s winning streak in 2012.
