Squash
Pickle ball Squash
Squash. Others include tennis and racquetball, but the ball is not as small as in squash and is not black. Tabletennis uses a very small bat and ball also. (Also Handball uses a similar ball and similar court to squash, but is hit with a gloved hand)

You stuff the squash ball in your top hand glove and what this effectively does is you can only use your bottom hand in a V. It is hard to get around the back of the bat with it, which means he improves your grip. --Harold
The sport is probably squash, although the ball doesn't have to be black.
The diameter of a tennis ball is 2.63 inches, or 6.7 centimers. A squash ball's diameter is between 39.5 and 40.5 millimeters.
