Tennis: Serena powers into Toronto final

World number one Serena Williams defeated Poland's Agnieszka Radwanska 7-6 (7/3), 6-4 on Saturday to reach the final of the WTA Toronto tournament.

The top-seeded American took her career record against Radwanska -- the world number four who is seeded third -- to 6-0, a run that included a triumph in the 2012 Wimbledon final and most recently in the semi-finals at Miami this year.

In Sunday's final she'll face unseeded Romanian Sorana Cirstea, who toppled fourth-seeded Li Na of China 6-1, 7-6 (7/5) in the semi-finals.
