Jo-Wilfried Tsonga of France moved into the China Open final when Feliciano Lopez retired from their semifinal on Saturday with a left wrist injury.
Tsonga was leading 6-1, 4-1 when the 30th-ranked Spaniard decided he could no longer continue playing. Lopez had the trainer on court after the conclusion of the first set.
In Sunday's final, Tsonga will play the winner of Saturday's later semifinal between top seed Novak Djokovic of Serbia and unseeded Florian Mayer of Germany.
Tsonga is 2-0 in finals this year, winning the Doha and Metz, France, titles.
