Iveta Benesova and Barbora Zahlavova Strycova are leading the WTA in doubles titles in 2011 with three, but they have had to fight for each of them.

The top-seeded Czechs were extended to match tie-breaks in the finals of their first two victories - at Sydney and Monterrey - eventually prevailing. Then on Saturday in the Barcelona final, once again they went to a match tie-break and this time actually had two match points against them, ultimately surviving third-seeded Natalie Grandin and Vladimira Uhlirova, 57 64 119.

Benesova and Zahlavova Strycova now have a 16-4 record on the year and eight titles in their careers together, one of those coming in 2008, one in 2009 and three in 2010. Benesova has 12 doubles titles to her name, while Zahlavova Strycova has 13.

Meanwhile, in Estoril, unseeded Alisa Kleybanova and Galina Voskoboeva captured their first title as a duo, defeating Eleni Daniilidou and Michaella Krajicek, 64 62, in Saturday's final. The champions were playing their fourth career event together, but first since 2008.

"I'm really happy because I didn't do so well in singles, so it was important for me to play some more matches and to have some good wins in doubles," said Kleybanova, who now has five career doubles titles with five different partners. "Galina and I have fun all the time. We're good friends, so whenever we get the chance to play together I'm happy because we feel good on the court together."

"Unfortunately we saw that Eleni had some injury problems coming into the match, but actually that didn't help us," said Voskoboeva, who now has two career doubles titles, the first coming alongside Dinara Safina in Kuala Lumpur two months ago. "All four of us were so nervous on the court, and Alisa and I struggled a bit with our concentration knowing that Eleni was injured. We needed to focus more on our game."
