And if I covered my bases, I was well prepared.
However, someone who is way off base did something wrong or maybe even dishonest or immoral.
A person with strange ideas might be described as out in left field.
Let us say I want to sell my car but I do not know exactly how much it is worth.
If someone asks me the price，I might give a ballpark figure or a ballpark estimate.
If someone offers me an amount that is close to my selling price, I might say the amount is in the ballpark.
However, if I say we are not in the same ballpark I mean we cannot agree because my ideas are too different from yours.
Finally, when a situation changes completely we say that is a whole new ball game.
