Aviary or bird netting over the area they 'free range'. The link below is for 100x50 but they come in all sizes. fence in the area and then cover the top with these. Put a few together and you can end up with a pretty large area for them to run in. If you use T-post for your fencing you can move it around once a year or so if you want too. My personal plan if for 200x100 area covered that I can just leave them in forever.

how much money do you want to spend?
Amazon sells a 100 foot by 50 foot net. Unfortunately the gaps in the next are about 2 inches. If you fold the net twice i reckon it'll catch ping pong balls. and it will a more manageable 50x25 feet.
A net will be by far the best tool.
its 80 dollars though. https://www.amazon.com/Anti-Bird-Netting-Aviary-Poultry/dp/B00CDL3LXC/ref=sr_1_9?keywords=netting&qid=1555431651&s=pet-supplies&sr=1-9
this one has a half inch mesh. Might be better. https://www.amazon.com/BEST-BIRD-NETTING-Bird-Net/dp/B01GUJBF3U/ref=sr_1_1?keywords=bird+net+half+inch+mesh&qid=1555431919&s=pet-supplies&sr=8-1
With a large enough net, and enough friends you should be able to catch all the ping pong balls.
