Anastasia Potapova has already beaten Elena Rybakina and Jelena Ostapenko on her run to the semi-finals
Anastasia Potapova has become the first lucky loser to reach a WTA 1000 semi-final thanks to her thrilling victory over Karolina Pliskova at the Madrid Open.
The Russian-born Austrian lost in qualifying last week but was given a place in the main draw when another player pulled out.
And she secured a 6-1 6-7 (7-4) 6-3 win over former world number one Pliskova in the last eight to continue her stunning run in the Spanish capital.
Potapova, 25, has made the most of her surprise chance in the main draw and - having already seen off former French Open champion Jelena Ostapenko and world number two Elena Rybakina - is through to the last four.
