Wozniacki rolls in Seoul opener

Former world No. 1 star Caroline Wozniacki was an easy first-round winner Tuesday at the $500,000 Korea Open tennis event.

The top-seeded Dane routed Dutch left-hander Arantxa Rus 6-1, 6-2 in 62 minutes on the hardcourts at the Olympic Tennis Courts, which hosted the tennis portion of the Summer Games in 1988.

Up next for Wozniacki will be France's Caroline Garcia.

Four other seeds joined Wozniacki in the second round, as No. 3 Estonian Kaia Kanepi drilled Korean wild card Sung-Hee Han 6-1, 6-0; No. 6 American Varvara Lepchenko topped Italian Camila Giorgi 6-2, 7-6 (7-1); No. 7 Czech Klara Zakopalova outlasted Spaniard Garbine Muguruza 6-4, 4-6, 7-6 (7-1); and No. 8 Russian Ekaterina Makarova cruised past Slovenian Polona Hercog 6-4, 6-1 on Day 1. Zakopalova was the Seoul runner-up two years ago.

An upset came when Spaniard Silvia Soler-Espinosa took out fifth-seeded German Julia Goerges 1-6, 7-6 (7-5), 6-2.

Additional wins came for the qualifier Garcia, Dutchwoman Kiki Bertens, Kazakhstan's Galina Voskoboeva, American qualifier Jamie Hampton, Slovak Magdalena Rybarikova, and Spaniard Anabel Medina Garrigues. Voskoboeva was last year's Seoul runner-up to Spaniard Maria Jose Martinez Sanchez. Rybarikova downed 41-year-old Japanese Kimiko Date-Krumm 6-4, 6-3 on Tuesday. Date-Krumm titled here in 2009 by beating Medina Garrigues in the finale.
