Tomas Berdych advanced to the semifinals of the Monte Carlo Masters for the third time Friday after Milos Raonic retired with a foot injury.

Raonic called a trainer after dropping serve for the second time to trail 5-2 in the first. Following a short discussion with the doctor, who had a close look at his strapped right foot, the big-serving Canadian went to see Berdych on the other side of the court to inform him of his decision to give up.

Berdych, who has yet to lose a set this week, will face either Grigor Dimitrov or Gael Monfils in the semifinals of the clay-court Masters tournament.

Eight-time champion Rafael Nadal will later play David Ferrer, and top-ranked Novak Djokovic will face Marin Cilic.
