Polish top seed Agnieszka Radwanska breezed through her first round match in the Seoul WTA tournament on Tuesday, brushing aside Romania’s Alexandra Cadantu in straight sets.

The 2012 Wimbledon finalist and world No.4 started off tentatively in the first set, but soon found her stride and finally overpowered Cadantu 6-4 6-0.

Russian second seed Maria Kirilenko also made short work of her first round opponent, Chan Chin-Wei of Taiwan, with a brisk 6-3 6-3 victory.

Kirilenko, who received treatment on her knee after the first set, said she was confident her fitness would hold out for the rest of the tournament.

“Injuries happen sometimes. I was in quite a bit of pain at one point, but I played through it and it subsided,” she said.

To the delight of the home crowd, the surprise of the round was provided by wildcard entrant Jang Su-Jeong, who ousted the fourth-seeded Czech Klara Zakopalova in little more than an hour, 6-3 6-1.

“I felt I had nothing to lose, so just went for my strokes,” the South Korean said.

“The crowd were great and helped me a lot.”

Japan’s Kimiko Date-Krumm, who won the Seoul title in 2009, came back from a set down to defeat Britain’s Heather Watson 3-6 6-3 6-4.

“Heather is a very, very tough player,” Date-Krumm said. “Today, I think I was lucky.”
