Sania Mirza and Martina Hingis clinched their 28th consecutive victory to equal the record for most wins in a row in women's doubles with a straight sets triumph in the quarter-finals of the Sydney International tennis tournament here on Wednesday.The Indo-Swiss combination overcame the Chinese pair of Chen Liang and Shuai Peng 6-2, 6-3 to enter the semi-finals and keep on track for their second title of the year.They have thus pulled level with Gigi Fernández and Natasha Zvereva, who won 28 consecutive matches in 1994 to set the present record. Sania and Martina hardly broke sweat, breaking their opponents' serve twice to win the first set easily. The top seeds were a bit erratic in the second set, wasting seven break points. But they did manage to break the Chinese pair twice, which proved to be enough.Sania and Martina, who are currently the top ranked team in women's doubles, have won 10 titles together. They won titles at Indian Wells, Miami, Charleston, Wimbledon, US Open, Guangzhou, Wuhan, Beijing and WTA Finals in 2015.They have already notched up a title win this year, winning the Brisbane International last week.
