Australian Samuel Groth and Andrey Golubev of Kazakhstan on Tuesday reached the men's doubles semifinals at the French Open in Paris.

The unseeded pair easily accounted for ninth-seeded Lukasz Kubot of Poland and Sweden's Robert Lindstedt 6-3 6-3 in their last-eight showdown.

In the semis, Groth and Golubev will face Julien Benneteau and Edouard Roger-Vasselin after the French 11th seeds downed Argentine pair Maximo Gonzalez and Juan Monaco 7-5, 4-6, 7-6 (5).

The unfancied Australia-Kazakhstan combination set up their unlikely march to the semifinals with a 7-6 6-4 second-round defeat of Spanish fourth seeds Fernando Verdasco and David Marrero.

In an earlier quarter-final upset, the top-seeded Bryan brothers of the United States lost 6-4 6-2 to another Spanish pairing of Marcel Granollers and Marc Lopez, seeded 12th.

This opened the draw dramatically for Groth and Golubev, with Benneteau and Roger-Vasselin now the highest-ranked pairings left in the tournament.
