Petra Kvitova stretched her winning run to 12 games as she booked her place in the final of the Doha Open.
The Czech, who is eyeing a return to the top 10, downed world number one and Australian Open champion Caroline Wozniacki 3-6 7-6 (7/3) 7-5 in a thrilling semi-final.
Wozniacki will be ruing defeat having twice served for the match in the second set, but Kvitova's resilience shone through and she is now one win away from a second successive title after her success in St Petersburg a fortnight ago.
Kvitova, who is now enjoying the longest winning streak of her career, will meet Spaniard Garbine Muguruza in the final.
Muguruza had the day off as she received a walkover in the semi-final following the withdrawal of Simona Halep due to a foot injury.
It will be both women's first final in Qatar.
