(Reuters) - Poland's Agnieszka Radwanska celebrated her rise to the top four of the world rankings with a 6-3 6-2 thumping of Alison Riske in the Shenzhen Open final on Saturday, her 18th WTA career title.
Radwanska had ensured she will replace Russian world number four Maria Sharapova in Monday's rankings by reaching the final of the tournament in China and backed that up with a routine victory over her American opponent.
"I think Alison was really playing solid tennis today," Radwanska told reporters. "She has a very powerful game from the baseline -- I was really struggling from the baseline.
