PETALING JAYA: World No. 16 S. Sivasangari adjusted to the best-of-three format in quick fashion to outplay local favourite Katie Maliff to reach the quarter-finals of the London Classic on Thursday.

The Malaysian, who is more familiar with best of five format which is used at the majority of the tournaments worldwide, wasn’t crippled by the shorter version as she defeated world No. 39 Maliff 11-6, 11-7 in 21 minutes.
