TORONTO (AP) -- Top-seeded Serena Williams advanced to the Rogers Cup final Saturday night, beating third-seeded Agnieszka Radwanska of Poland 7-6 (3), 6-4.

The 2001 and 2011 Rogers Cup champion will face Romania's Sorana Cirstea, a 6-1, 7-6 (5) winner over fourth-seeded Li Na of China in the afternoon semifinal.

Williams has seven tournament victories this year and 53 overall. In her last event, she won the Swedish Open on July 21.

The 27th-ranked Cirstea ousted two former world No. 1s in Jelena Jankovic and Caroline Wozniacki this week and beat sixth-seeded Petra Kvitova in the quarterfinals.

''A new day, a new match,'' Cirstea said. ''It doesn't matter who I beat the day before or what I've done. It's just another day where I have to get out there and do the things to show the work that I've put in.''

Williams has played Cirstea twice and handily won both meetings. Cirstea won her lone WTA Tour in 2008 at Tashkent.

Radwanska and Williams traded breaks twice in the first set, with the Pole keeping up with Williams's imposing power game. Radwanska dashed corner-to-corner at the baseline to make returns and led 6-5, but Williams held serve to force a tiebreaker. In the tiebreaker, Williams blasted a cross-court winner for a 6-3 advantage, then aced set point.

Williams called for a medical timeout early in the second set because of ''gastrointestinal issues.'' She looked slightly out of sorts early in the set, going down a break and screaming at the ground after blowing an easy overhead smash.

But that didn't last.

Williams broke back and took a 4-3 lead by running Radwanska around the court with blistering offensive groundstrokes. She won a nearly 10-minute game to pull ahead 5-4 and broke Radwanska to finish off the match in 1 hour, 52 minutes.
