Unseeded Romanian Sorana Cirstea earned the biggest win of her career with a 6–4 6–4 victory over Australian Open champion and world number two Aryna Sabalenka on Wednesday to reach the Miami Open semifinal.
Cirstea, who has yet to drop a set in Miami and is the last unseeded player in the draw, delivered a stunning performance while taking advantage of some untimely double faults to become only the third person to beat Sabalenka this year.
