Playing style
Tanner was known for his unorthodox, very strong left-handed serve that was tossed very low and struck with a lunge involving the whole body, earning him the nickname "The Rocket". His game consisted of a powerful serve with an approach to the net and strong volleys.
In a video for Jack Kramer, Tanner said, "The offensive style of game which is closest to my heart is basically the attacking style... that is a serve and volley type of game. That's really moving at the other player, picking out their weaknesses and attacking them, being aggressive." Tanner played with a PDP Open racket, which was the "stiffest" racket on tour at the time, which added speed and power to his strokes and volleys.
