Ok, so, so.
This game doesn't have any real tennis pro personalities in it, not even one. The players you choose from are broken down by countries, and look like they stepped out of a bad version of Street Fighter.
But it's a tennis game. Do not buy this game, unless you have to have a tennis game added to your sport collection games. It's not that challenging, and poorly done. I've played this game for a grand total of 15 minutes, and haven't touched it since. Give me some Maria.
