Nick Kyrgios stood amazed, his mouth agape and his eyes popped wide over a shot his opponent had just made in the third set of their third-round match on Saturday.
Kyrgios had scooped a drop shot at a seemingly safe angle, but Roger Federer sprinted a few feet wide of the doubles alley, reached down with the head of his racket about two inches off the surface of the court, and tapped a forehand around the net post.
The ball lifted less than a foot into the air and bounced past Kyrgios, a winner for Federer.
