POLAND'S Agnieszka Radwanska will play for the No. 1 ranking in tonight's Wimbledon final but there's no denying who the world's best female tennis player is when she's on top of her game.
That would be the other finalist, Serena Williams.
Such was the American's dominance over world No.2 Victoria Azarenka on Thursday, the 13-time major champion goes into her seventh final at the All England Club as overwhelming favourite.
"Power, court coverage and confidence," 18-time major champion and ESPN analyst Chrissie Evert surmises of Williams's strengths.
"When those three things are working like they seem to be now - she's invincible."
Williams served the Belarusian off the court, throwing down a Wimbledon record of 24 aces - the equivalent of six games - in her 6-3 7-6(6) semi-final victory. The previous Wimbledon record of 23 aces was also set by Williams in a three-set victory over Zheng Jie in the third round. She has now hit a staggering 85 aces in six matches.
The No.3 seed Radwanska, playing in her first major semi-final, beat German Angelique Kerber 6-3 6-4 in 70 minutes. Radwanska is guaranteed to move to a career high No.2 but Azarenka can still take the top spot from Maria Sharapova should Williams win the final.
Radwanska, who won the 2005 junior Wimbledon title, is the first Polish woman to reach a major final since 1939, when Jadwiga Jedrzejowska lost in the French Championships.
In the past 12 years, Serena and sister Venus have combined to win nine Wimbledon singles titles, and now it could well be 10 of 13. That would give them five each.
Williams, 30, is also seeking to be the first 30-plus player to win a major in 22 years - Martina Navratilova, then 33, won 1990 Wimbledon.
And with that age comes a more modest Williams, who more often than not these days says all the right things.
"Radwanska has been playing well. She won Miami. She's been consistent this year, more consistent than I have," she said. "That already tells me from the beginning I really need to go out there and be ready to hit a lot of shots and be ready to play hard."
But Williams has never lacked self-belief.
"I'm Serena Williams, I'm very confident," she said earlier in the tournament, when posed a question on confidence.
With that warning, look out Radwanska.
