By defeating Bjorn Phau and reaching the quarterfinals of New Haven, Sam Querrey has overtaken Andy Murray and won the men's US Open Series.

Querrey wins the title because he has 14 match wins in series events, compared to eight for Murray.

In the women's singles, Flavia Pennetta still has a shot at winning the women's US Open Series, but needs to win the title in order to overtake Elena Dementieva.

The Series winner gets double prize money at the US Open, with one and a half times the prize money for the second place finisher and one and a quarter times for the third place finisher.

Oh, no! Svetlana Kuznetsova teaches kids about fashion!

We know Svetlana Kuznetsova has shown some great improvement in recent photo shoot.

But that doesn't mean her fashion sense has improved too.

Worse thing, she has committed an ultimate fashion crime by teaching the kids to accessorise like her (and proud of it)!

Kuznetsova was at the Girl Scout Night, a Sony Erricsson WTA Tour's Pilot Pen Tennis promotional event.
