Tshooter, the author's name is 'Scoop' Malinowski, according to his bio found from google he's a decent local player, has won 20 something amateur tournaments. Don't know about you but that's a lot more than I ever won!
Peter Bodo and Jon Wertheim are not very accomplished players but they do know tennis to an exceptional degree me thinks.
