"I think Etymonline at least supports the premise that the origin of 'Sales Pitch' derives from the meaning of 'Pitch' as "to throw" dating from 1833
pitch (n.1) 1520s, "something that is pitched," from pitch (v.1). Meaning "act of throwing" is attested from 1833. Sales pitch in the modern commercial advertising sense is from 1943, American English, perhaps from the baseball sense.
In this sense one is "pitching" (throwing) something to the listener, in the same way that you can 'pitch' an idea. It is a short leap from there to 'pitch' your sales patter to a potential buyer, which becomes naturally a Sales Pitch."
