I’ve recently met several tennis players who also play pickleball, sometimes even after playing an hour of solid tennis! One A player I know said pickleball has definitely helped him with better tennis, such as footwork and positioning, angled shots, arm motion, watching the ball, continuation, lobbing, and running a lot if PB singles. When I played a bit of pickleball I noticed how low I had to get under the ball, react to balls with no pace, hit harder and through for smash shots, hit harder serves, and really watching much more intensely. Plus, it’s a LOT cheaper.
However, PB is so popular now there are huge lineups or competition to even get to play, especially if game matchups are all organized for players. Clubs everywhere are feeling the heat to either add or convert courts for pickleball. Most PB players play doubles, which some tennis players like myself don’t prefer. Singles pickleball also appears just too difficult or almost impossible to get some shots back from good PB players.
