The point is yours. Players must let the ball bounce. If the ball hits the player, he/she loses the point, even if the ball hits the player while the player is standing right next to the back fence, 20 feet behind the baseline!!
"Rule 24. PLAYER LOSES POINT
The point is lost if:
i. The ball in play touches the player or anything that the player is wearing or carrying, except the racket"
My comment: The key phrase here is "in play." Once the ball bounces out, it is no longer in play. Also, it doesn't matter if this happens on the serve or a shot later on in the point. Notice that Rule 24 i. didn't specify which shot in the point was being considered.
