I recently played a guy who had learned tennis as an adult. He was pretty good for picking it up so late, and his backhand was very nice, forehand wasn't as good. He said his backhand was from playing ping pong, which made sense. I've also read that Paul Goldstein grew up playing ping-pong and Sam Querrey is also a big ping pong player. So is ping pong the best way to learn tennis, for a kid?
