Have you ever tried to extract a tightly-embedded screw with a thin-handled screwdriver? It’s tough to twist. So get a larger tool and the job becomes easier.

Tennis balls hit your strings at varying angles with varying spins and this twists your racket. Try a bigger grip to resist the torque. A larger handle will also restrict your wrist flicking and snapping, which should increase your control.

Do a cheap experiment: Add overwrap to your handle and increase its size until it feels right. Then take your racket to a pro shop and have your handle professionally built-up with vinyl heat sleeves. Let the pro put on a fresh replacement grip while you’re there.

Most players benefit from the increase but if you change your mind, it’s reversible.
