Unseeded Ukrainian Lesia Tsurenko advanced to the final four of the Thailand Open by beating German sixth seed Tatjana Maria 6-1, 6-1 on Friday in Hua Hin, Thailand.

Tsurenko, who upset No. 4 seed Anna Kalinskaya of Russia in the previous round, won a whopping 72.4 percent of her first-service points (21 of 29) and converted six break points in 10 opportunities to oust Maria.

In the semifinals, Tsurenko will face No. 1 seed Bianca Andreescu of Canada, who was a 6-0, 7-6 (3) winner over Ukrainian fifth seed Marta Kostyuk. Andreescu led 5-1 in the second set but had to come back after Kostyuk won five straight games to briefly move ahead. The Canadian then rallied from a 2-0 deficit to start the tiebreak.

China’s Xinyu Wang and Lin Zhu will meet in the other semifinal match. Wang, the No. 7 seed, outlasted Heather Watson of Great Britain 6-3, 6-7 (6), 6-4. Zhu beat Tamara Zidansek of Slovenia 6-2, 6-2.
