Fourth seeds Leander Paes [ Images ] and Martin Damm [ Images ] went down to top seeds Bob and Mike Bryan [ Images ] in the semifinals of the USD 2,200,000 Cincinnati Masters in Toronto, Canada [ Images ].

The Indo-Czech pair squandered a one-set lead to go down 3-6, 6-0, 10-7 to the Americans, who advanced to their 12th final this year.

The top seeds will take on the sixth seeded Israeli duo of Jonathan Erlich and Andy Ram [ Images ], who defeated Czechs Lukas Dlouhy [ Images ] and Pavel Vizner 7-6 (4) 7-5, in the finals on Sunday.

Paes and Damm were off to a brilliant start as they broke Mike Bryan's first service game en route to capturing the first set.

However, the Indo-Czech pair completely lost the plot in the second set and was blanked out by the Bryans.

The top seeds then raced to an 8-2 lead in the tie-break but Paes and Damm recovered to cut the lead to 8/7.

The comeback, however, proved to be too late as Bob Bryan fired a couple of un-returnable serves to clinch the match after 58 minutes.

The Bryan brothers have already won a personal-best eight titles this year.
