SEOUL, South Korea (AP)—Top-seeded Agnieszka Radwanska of Poland won 6-0, 6-0 for the fourth time in a WTA main draw on Wednesday.
Chanelle Scheepers of South Africa was the latest to be ''double-bageled'' by Radwanska, in the second round of the Korea Open.
Defending champion Radwanska lined up fifth-seeded Varvara Lepchenko of the United States, who ousted South Korean wild card Han Na-Lae 7-5, 6-1.
Radwanska leads Lepchenko in their head-to-head 5-1, but Lepchenko's win came in their last meeting in the second round at Stanford in July. That win also served as Lepchenko's first win over a top-five player.
Second-seeded Karolina Pliskova of the Czech Republic outlasted Anna-Lena Friedsam of Germany 6-4, 6-7 (5), 6-2, and Christina McHale of the U.S. beat Mona Barthel of Germany 6-1, 4-6, 6-3.
