As you know already the grammar does not allow using verbs in a row like this:
I like play every day.
Right would be:
I like to play every day.
I like playing every day.
So I guess there is no need to explain it more properly.
However, is the verb go an exception?
I often read and hear things like:
Go play elsewhere!
Go saw something!
(And many more.)
Is it grammatically correct?
Maybe it is correct because it is call?
And I'm sure it is not "Go... saw something".
It comes right after the go - they are linked together.
You need the infinitive form of the verb.
Go play outside.
Go make that noise somewhere else.
Go jump in a lake! (That means "go away")
Go watch TV now - mommy's trying to balance the checkbook.
So "Go saw" isn't right at all.
It's also a presumptive way to tell someone to do something - something a parent would say to a child, for example.
