Smooth sailing for Agnieszka Radwanska

The Pole disposed of Romania's Sorana Cirstea 6-0, 6-3 in an hour and 18 minutes.

Top seed and world number three Agnieszka Radwanska made short work of her second round opponent at the WTA Shenzhen Open on Tuesday.

The Pole disposed of Romania's Sorana Cirstea 6-0, 6-3 in an hour and 18 minutes. Cirstea, ranked 78th in the world, lost more than half the points she served and faced 14 break points, losing six of them.

It was a contrast to the defending champion's first-round match on Monday, when she took nearly two and a half hours to overcome a stiff challenge from a 103rd-ranked Chinese opponent.

Britain's Johanna Konta, who has begun 2017 as a top 10 player for the first time in her career, had a scare of her own against 77th-ranked Vania King of the US on Tuesday, losing the first set 1-6.

Konta recovered to prevail 1-6, 6-3, 6-2 in an hour and 35 minutes.

But unseeded home player Wang Qiang caused an upset, putting out seventh seed Monica Niculescu of Romania 7-6 (7/1), 6-4, in a gruelling encounter that lasted more than two hours even though the pair only played two sets.

In the day's other singles match at the $750,000 tournament in the southern Chinese city of Shenzhen, American eighth seed Alison Riske beat Bulgaria's Tsvetana Pironkova 6-1, 6-1.
