Naomi Osaka said she felt “really scared” after watching opponent Daria Saville collapse with a knee injury just seven minutes into their Pan Pacific Open match in Tokyo on Tuesday. Australian Saville retired from their first-round encounter after hurting her left knee hitting a cross-court forehand in the second game of the match. The World No.55 yelled out “my knee” before dropping to the ground in agony, and Osaka rushed over to her side of the court to check on her opponent.
