We played Wiffle Ball from 5-6 years old to grown men down Ocean City with the ocean/bay as the back drop, and I still wish I played ... thats how I learned to swtch hit, we played two ways actually....
In the earlier years we found these 'different' wifle balls...Where if you added a strip of black tape around one side of it gave it just enough weight to make the game great! The ball would travel farther but not too far, and the ball would kind of glide thru the air where you could make great catches as it would hang up in the air....Also if you connected just right, the ball would sail majestically thru the summer sky like a Reggie Jackson blast into the upper deck,lol...The problem was Toys R Us stopped selling the ball, we had to preserve the balls at all costs, eventually we ran out of them and had to revert back to the classic Wiffle Ball....
In the later years using the Wiffle ball we all played with, the rules became different as time went by...We never called balls and strikes really, but did allow all kinda of wicked pitches, the side arm riser, the sinker, the slow curve, the curve you snapped off 12-6, I never could throw a good knuckle ball,lol... We ended up finding this perfect Wiffle ball Stadium, we would actually drive 20 minutes to play at, thats how serious it was back in the day...I'm sure the local people that lived in the townhouses right across the field thought we were nuts, we would play at 3-4 in the morning sometimes!!!
We would run the bases and one of the rules was you could throw the ball at the runner, I have no idea how that rule started but it seems everyone played this way at some point...
In the last edition of my Wiffle Ball career, the rules were refined, and we didn't run the bases at all, we allowed fast pitching , the mound distance was very close, which simulated 90MPH fastballs..We were only allowed to throw straight fastball, no curves, so it was about location and fast pitching...This was probably the best way we played the game, or atleast it seemed to fit at this point in time...Anyway, the rules were; if the ball went over the fence it was a home run, off the wall in the air a triple, if it bounced to the wall a double, a single was a grounder that stopped completely, without the opponent touching it, if he picked it up without commiting an error it was an out if he booted it, a single...If the ball was popped up it had to be caught on one bounce or out of the air or it was ruled a basehit...These rules were perfect for one on one play !
