SHENZHEN, China – World No.5 Agnieszka Radwanska registered an expected win, in unexpected circumstances, to get her 2016 campaign up and running at the Shenzhen Open.

Heavy rain forced the tournament organizers to move the majority of Tuesday’s order of play indoors, although the change of venue failed to distract Radwanska, who needed little over an hour to outfox Krunic, 6-4, 6-3, in her first match since lifting the BNP Paribas WTA Finals Singapore presented by SC Global.

“Of course we all saw the weather and knew it would be difficult,” Radwanska said. “There was not much time to wait and I was prepared for that. Of course I came here to play outdoors, but we both had the same conditions and I’m happy I played my match today.”

With memories of Singapore fresh in her memory, Radwanska did not take long to knock off any rustiness, saving three break points in the second set to keep another of the game’s more cerebral competitors at arm’s length.

“I feel like I played my last match in Singapore a week ago! It’s always tough to come back to the match rhythm, but actually I was feeling really good and didn’t have any problems doing what I wanted to do on court and for the first match I played good tennis so I’m happy with that,” she added.

“I think the first matches are always the worst and the toughest. Every tournament has different conditions, especially here – I’ve never played indoors at a tournament that was outdoors. It’s a little bit of a new experience but everything went well so that’s the most important thing.”

In the second round the Pole will face wildcard Zhang Shuai, a 6-3, 6-3 winner earlier on over Irina Khromacheva. Elsewhere, there were mixed fortunes for three of Radwanska’s fellow seeds, Petra Kvitova, Eugenie Bouchard and Johanna Konta.

No.6 seed Bouchard put her difficult 2015 season behind her with a determined performance against Donna Vekic, overcoming a mid-match blip to come through, 6-4, 1-6, 7-5.

Unlike Bouchard, Konta, the No.5 seed, arrived in China with plenty of momentum after a brilliant second half to the previous campaign. However, in her first seeded outing at a WTA event, she slipped to a surprise defeat to Wang Qiang, going down to the World No.110, 6-3, 3-6, 6-3.

In the final match, Kvitova’s Australian Open preparations suffered a setback when she was forced to retire midway through her match against Zheng Saisai with a gastrointestinal illness. Zheng, who took the first set 6-2, will now meet Anett Kontaveit for a place in the quarterfinals.
