Michael Chang won the French Open semi-final against Lendl serving underhand.
LOL, (under-handed serves).

Why isn't it done more often in tennis?
We throw change-ups, forkballs, screwballs and other off speed pitches in baseball (and they are hard to hit). Why not in tennis?
If this is a stupid question by me, it wouldn't be the first time, but it seems that it would actually make the game of tennis more entertaining. Getting those service returners to think about something else has to be great for the game.
I'd like to read about that.
