^this, being taller gives you more torque on the backswing, hence more natural/effortless power. Look at baseball and also golf. shorter golfers need to rely heavily on their short game all the time. It's physics
Messi is an exception to short athletes what an amazing guy.
Perfect tennis height is 6'1-6'2 imo, gives power and doesn't hinder movement or trouble hitting slices.
Novak is 6'3 but he also has a long head and neck -
