News flash, you can play tennis and pickleball. I'd rather play tennis than pickleball any day of the week. But especially during the winter there is no place to play that doesn't want an arm and a leg. And it's hard to find someone willing to play singles with. I can go to a few indoor places most days of the week and play relatively competitive pickleball and even occasionally find someone willing to play singles (which in my opinion is even more fun than doubles tennis). People say it hurts your tennis game but I've gone directly from one to the other in a few minutes without any issues. Really the biggest draw for me is the availability and that it satiates my tennis craving till the warm weather hits. I'll never give up tennis for pickleball, but I certainly have a much higher chance of winning a 4.5 pickleball tournament than I do a 4.0 tennis tourney and I'll just compete in both and have fun.
Also Christian Alshon, who was I believe was one of the top D1 college tennis players a few years ago quite college tennis and is also now a top pickleball pro and doing pretty well.
