Svetlana Kuznetsova beats nerves, Agnieszka Radwanska to win San Diego Open

Svetlana Kuznetsova overcame a bout of mid-match nerves to grind down Agnieszka Radwanska 6-4 6-7 6-3 and clinch the San Diego Open on Sunday.

The Russian Kuznetsova blew four match points in the second set tiebreak to gift Radwanska the set but roared back into life in the third to take her first title in 10 months.

"I just shook," said Kuznetsova, who was playing in her first final for the year.

"The trophy was very important to me. I was very embarrassed and I just got it back together and dictated," added Kuznetsova.

The victory provides a timely return to form for the double grand slam champion ahead of the US Open, and will propel her to 14th when new rankings are released on Monday.
