Raonic retires from match at Japan Open

TOKYO - Milos Raonic picked up another injury Thursday and was forced to retire from his second-round match at the Japan Open.

The 2016 Wimbledon finalist lost the opening game against Yuichi Sugita and then decided to stop while trailing 1-0 because of a right-calf injury.

After winning his first match back from a seven-week absence following surgery on his left wrist, Raonic complained that the tennis tour was too demanding and called for a review.
