Tomas Berdych defeated Andy Roddick 6-7 (3-7), 7-5, 7-6 (7-3) in the semifinals of the Japan Open on Saturday, ending the second-seeded American's bid for a second straight title in Asia.
The ninth-seeded Berdych will face fifth-seeded Juan Martin Del Potro of Argentina in Sunday's final. Del Potro defeated No. 4 Richard Gasquet 6-3, 4-6, 7-5 in the other semifinal.
Roddick, coming off a win at the China Open last Sunday, broke Berdych to take a 2-0 lead in the final set and looked set for another trip to the finals after building up a 5-2 lead.
