In the quarterfinals at the Hana Bank Korea Open on Thursday, Polina Kudermetova (ranked No. 163) meets Beatriz Haddad Maia (No. 17). Haddad Maia has won 66.7% of her service games over her last 10 tournaments, and 41.9% of her return games.

Ajla Tomljanovic's hopes of adding another trophy were dashed in Korea as Brazilian No.3 Beatriz Haddad Maia claimed the pair's Round of 16 clash.

Brazilian star Beatriz Haddad Maia has proved too powerful for Anna Tomljanovic, beating the Australian 6-3 6-4 to advance to the WTA quarter-finals in Seoul. Haddad Maia broke Tomljanovic's serve three times on her way to the last eight of the Korea Open, where she will meet Polina Kudermetova.

No.3 seed Beatriz Haddad Maia held off a late charge by Ajla Tomljanovic from 5-1 down in the third set to 5-4 to reach the Hana Bank Korea Open quarterfinals.
