Petra Kvitova came from a set down to beat world number one Caroline Wozniacki on Saturday to record her 12th successive victory and advance to the Qatar Open final. The Czech star won 3-6, 7-6 (7/3), 7-5 to set up a final against Spain's Garbine Muguruza on Sunday. It will be Kvitova's second final this month, after already winning in St Petersburg. Currently the world number 21, the final in Doha also underlines her push to get back to the elite of the women's game following a horrific knife attack at her home 14 months ago. If she wins the final, Kvitova could go back into the top ten in the rankings.
