The speed of a tennis ball is generally measured right off the racket, and it’s only going to slow down, not speed up. That said, a tennis ball that comes off the racket face at, say, 115 mph is going to get to the receiver sooner than a ball hit at, say, 100 mph, notwithstanding that both will slow before getting to the receiver.
There are two major factors that slow the ball. One is the flexibility of the ball itself. If you’ve ever seen a photo of a ball at the instant of impact, you can see that the diameter of the ball increases because the impact flattens out the ball.
