NEW HAVEN, CT, USA - The first two doubles matches of the Pilot Pen Tennis at Yale took the courts on Monday and already the first major upset was pulled off, as No.2 seeds Lisa Raymond and Rennae Stubbs were edged by Raquel Kops-Jones and Alla Kudryavtseva in a match tie-break, 57 62 105.

Raymond and Stubbs, finalists at back-to-back Premier tournaments in San Diego and Cincinnati in recent weeks, were up 75 21 with a point for 75 31 when Kops-Jones and Kudryavtseva caught fire, winning five straight games to take the second set and winning the first four points of the match tie-break. Raymond and Stubbs caught up to within two points at 7-5 but ultimately fell.

"We started slowly as it was our first time playing together, but we combined well in the end to win," Kops-Jones said. "Having played Lisa and Rennae three times in the last month and beaten them before gave me confidence. It was tough conditions for all of us, as it was very windy, but we played well together."

Raymond and Stubbs had won this title together once before, in 1999. Raymond had won it twice more with other partners - Sam Stosur and Kveta Peschke.

In the other doubles match of the day, Hsieh Su-Wei and Peng Shuai beat Maria Kondratieva and Vladimira Uhlirova, 62 76(7), coming back from triple set point down at 3-6 in the second set tie-break to close it out in two.

Hsieh and Peng have won four doubles titles as a team, one International-level in 2008 (Bali) and three Premier-level in 2009 (Sydney, Rome and Beijing).
