Title: Is it legal in racket sports to pass the racket from one hand to the other?
Question: Can you hit with different hands during the same  point? set? match?  Also, is racket throwing authorised?

Answers:
sents: text: Yes, it is LEGAL to switch racket "handed-ness" during play.
text: From the USTA web site : Q. I am a left-handed tennis player.
text: During play, I have found that I can hit the tennis ball almost as well with my right hand as I do with my left.
text: Do USTA rules forbid players to switch hands during play?
text: A.
text: No.
text: You can play with either hand.
text: In fact, three-time USTA national champion Marty Devlin of Trenton, NJ has employed this “two forehands” style since he started playing tennis.
text: The old joke when people were preparing to play Marty was to hit to his backhand.
text: But, alas, he has no backhand.
text: Also, I have cousins in the Miami area who have played tennis with Jai alai players who will switch handed-ness frequently even during the same point / rally.

sents: text: I know that in tennis you are allowed to use either hand to hit the ball with the racquet during any point, set or match.
text: You may not use more than one racquet during any single point, though (though you are allowed to switch racquets between points).
text: And racquet throwing (for the purpose of hitting the ball) is not allowed - the racquet must be in your hand at the point of contact or you lose the point.
text: It is perfectly legal though, between shots, to drop the racquet and pick it back up and continue the point.
