Safarova leads their head to heads 2-1. Their last meeting was Most recent Feb 2014. Safarova won in Doha on a hard court in 3 sets. Their other matches were on clay.
Saf has so much talent but her form has been very fragile this year. She needed 3 sets to beat Knapp in the last round.
Flipkens has a good record on hard courts and beat Venus Williams in the last round in 3 sets. She faced 21 bp in that match and was broken 6 times.
This really looks like a 3 setter. Flipkens has better hard court stats this year but Safarova has had real issues in confidence. She has shown signs of improvement recently.
Back Saf if she loses set 1
