American great Serena Williams will face Poland's Agnieszka Radwanska in Saturday's lucrative women's final at Wimbledon.

Williams will appear in her seventh Wimbledon final, seeking a fifth championship, while Radwanska will compete in only her first-ever major title match.

In Thursday's semifinals at the All England Club, a battle of former world No. 1s saw a sixth-seeded Williams beat second-seeded Belarusian star Victoria Azarenka 6-3, 7-6 (8-6) and a third-seeded Radwanska roll past eighth- seeded German Angelique Kerber 6-3, 6-4 on Centre Court.

Williams landed in her 18th major final (13-4), while Radwanska became the first Polish Grand Slam finalist in 73 years, or since Jadwiga Jedrzejowska lost in the women's title match at the French Championships in 1939.

Radwanska, who has been slowed by a respiratory illness the last couple of days, can become the No. 1 player in the world with a stunning victory over Williams on Day 12 of the fortnight.

The heavy favorite Williams is 2-0 lifetime against Radwanska, including a Wimbledon quarterfinal victory four years ago.

Williams is seeking the 42nd overall title of her brilliant career, including a third this season. She's already titled in Charleston and Madrid in 2012.

The 30-year-old star and her older sister Venus have combined to win nine of the last 12 Wimbledon titles.

Last year's U.S. Open runner-up Serena is 4-2 in her previous Wimbledon finals, as she titled back-to-back here in 2002 and 2003 and 2009 and 2010.

The 23-year-old Krakow native Radwanska, a junior Wimbledon champ in 2005, will appear in her 13th career WTA final, seeking an 11th title. She's 3-0 in her 2012 title tilts.

Saturday's big winner will collect $1.8 million.
