Cincy Semis: Serena vs Li Na

[GameSetAndMath]

That's not accurate GSM. Serena has never won the series and open in same year. She won the series in 2011 with titles in Stanford and Toronto, but lost the USO final to Stosur. The USO runner-up gets 1/2 mil if they win the series. Kim is the only woman to win the series and the open in the same year to get the bonus. That was 2005.

You are right. I made an unforced error. Kim Clijsters is the only one to win the Bonus
Challenge and the USO in the same year and that year is 2005.

On the Men's side Roger Federer is the only one to do so. He could do so only in
one year viz. 2007.

However, there is no error in Serena Clinching the Bonus Challenge part as the
players ranked second and third in that are not playing next week and so no one
has any chance of overthrowing Serena from the top spot.

Let us Serena becomes the second woman to do the double.
