Points to look for:
- The shoulders, hips and waist have all turned a little more to the player's left, which will reduce the amount of movement necessary to get into a neutral ready position.
- As shown by the medium sized blur trail, the ball is moving with more pace than for short serves, since only some of the speed of the bat has been converted into spin, while the rest was used to provide forward motion.
- The player is watching the flight of the ball, to judge how successful the serve has been.
- The ball has bounced very close to the endline of the server, which is typical for long serves.
