Bangkok: Top-seeded Tomas Berdych needed nearly three hours to outlast Gilles Simon of France 6-7 (5), 6-2, 7-5 Saturday and reach the final of the Thailand Open.
He will play Milos Raonic of Canada, who also came from a set down to oust defending champion Richard Gasquet 3-6, 7-5, 6-4.
Simon saved four set points in the 10th game of the first set and was down 5-3 in the tiebreaker before winning the next four points, clinching it when Berdych sent a forehand into the net.
But Berdych took a 3-0 in the second and broke his opponent in the 11th game of the decider to reach his third final of the year.
The hard-serving Raonic hit 23 aces and broke Gasquet once in each of the second and third sets.
