Defending champion Agnieszka Radwanska cruised into the quarterfinals of the Tianjin Open with a 6-1, 6-1 win over Evgeniya Rodina on Thursday.
The top-seeded Radwanska broke her opponent five times and won all but four points on her first serve in the match. She has now won her last eight matches, starting with her run to the China Open title last week.
Radwanska next plays Chinese veteran Peng Shuai, a former U.S. Open semifinalist who beat Chang Kai-Chen 6-3, 6-2.
Olympic gold medalist Monica Puig also reached the quarterfinals with a 6-4, 6-2 win over Lara Arruabarrena, and Alison Riske advanced with a 6-3, 7-6 (2) victory over Magda Linette.
