Nick Kyrgios's serve
Traced frame by frame from real footage.
Kyrgios's serve is hard to read because every serve looks the same. The toss is low for a tall player, the motion quick and simple, and wide and T serves share the same toss and body movement. He hit 30 aces in the 2022 Wimbledon final.

- 1The motion is compact: the racquet drops and swings up in few, quick positions.
- 2He's fully off the ground at contact, reaching up through the ball.
- 3He lands on the front foot, already falling forward into the court.
Our own observations from the traced frames. Flip through the plate above to check them.
By the numbers
He doesn't toss high and makes contact slightly below the top of the toss, with a very quick wind-up. Overlays of his wide and T serves show the same toss, body movement and contact.

The copyable idea is sameness: one toss and one motion for every serve, so the returner reads nothing until the ball is struck.
