SHENZHEN: Agnieszka Radwanska scored a comfortable 6-3, 6-2 victory over Alison Riske of the United States on Saturday to win the Shenzhen Open. The top-seeded Pole continued her fine form from the end of last season when she won titles at Tokyo, Tianjin and the WTA Finals in Singapore. Radwanska, who is set to go up to fourth in world rankings ahead of this month's Australian Open, served nine aces and saved both break points she faced, on way to her 18th career title. Riske saved four of seven break points in the final.
