Indian tennis ace Sania Mirza and her Swiss partner Martina Hingis notched up their 38th straight win to reach the semifinals of the women's doubles event of the St. Petersburg Ladies Trophy on Saturday.
The top-seeded pair continued their rampaging form in their 6-4, 6-1 demolition of the unseeded Russian duo of Daria Kasatkina and Elena Vesnina in the quarterfinals.
Sania and Hingis will next face the third-seeded pair of Anabel Medina Garrigues and Arantxa Parra Santonja later in the day to secure a spot in the final.
Earlier this year, the Indo-Swiss duo won their third consecutive women's doubles Grand Slam title by lifting the Australian Open trophy.
Since an upset loss in the French Open quarterfinals, the Indo-Swiss duo has been unstoppable, winning 42 of the next 45 matches to take home titles at Wimbledon, the US Open, Guangzhou, Wuhan, Beijing, the WTA Finals in Singapore, Brisbane and Sydney.
