Sam Querrey already clinched the men's U.S. Open Series title meaning he would win an addition $1 million if he were to win the U.S. Open title.

Now it is Flavia Pennetta's turn to earn some extra cash.

With Marion Bartoli and Samantha Stosur being eliminated from the Pilot Pen on Wednesday, Pennetta clinched a top three finish in the women's U.S. Open Series. If Pennetta beats Magdalena Rybarikova today, she would move up to second place. Actually, she would be tied with Jelena Jankovic but Pennetta would finish ahead of Jankovic because she has more match wins in U.S. Open Series events. Pennetta would need to win the New Haven title to beat out Elena Dementieva for the U.S. Open Series title.

The winner will double his or hers singles paycheck at the U.S. Open, the second-place finisher would get a 50 percent bonus with 25 percent going to the No. 3 finisher.

The bonuses could range from $3,750 to $1 million. Kim Clijsters in 2005 and Roger Federer in 2007 are the only players who have won both the U.S. Open Series and U.S. Open title.
