BEIJING, Oct. 8 (Xinhua) -- Canadian third seed Milos Raonic on Saturday announced that he will retire from the China Open due to a right ankle injury sustained in his second match with Spaniard Pablo Carrerno Busta in the previous day.

Raonic said that he sustained the injury in the third game of the match, "rolling over" his ankle and causing a sprain.

"I did a test this morning when showed I had a partial tear on the outside of my ankle. I was told to give it a try. I tried to warm up just before the match like I would normally, and I was unable to play," he said.

Raonic still intends to travel to Shanghai for the upcoming Masters, where he said a bye will allow him to get a later start and with it, several days of time to recover.

Raonic's retirement means that Bulgarian Grigor Dimitrov will face Britain's Andy Murray in Sunday's final.
