HONG KONG — Top-seeded Elina Svitolina kept alive her chances of reaching the WTA Finals in Singapore by beating Australian wild card Priscilla Hon 6-2, 6-3 at the Hong Kong Open on Tuesday.

Fourth-seeded Garbine Muguruza gave herself a belated birthday present by defeated Spanish compatriot Sara Sorribes Tormo 6-3, 6-1.

The seventh-seeded Daria Gavrilova, a Hong Kong finalist last year, got past Zarina Diyas of Kazakhstan 3-6, 7-5, 6-1.

Japanese qualifier Nao Habino defeated Australia's Samantha Stosur 6-3, 6-3.
