"grandfather" = (baseball) error?

[Gerald Cohen]

    In his Oct. 12, 2001, message ("John Crosby's Radio and
Television...) Barry Popik reprints a 1952 NY Herald Tribune article
on the baseball lingo of sports announcers. At one point the article
says: "... the particular effulgence...of the sports announcers.
There is no such thing as an error any more.  It's a miscue,
grandfather, or at very least a misplay."

     Grandfather? This term does not appear in Paul Dickson's _New
Baseball Dictionary_, and I never came across it before.  Has anyone
ever heard "grandfather" as a baseball term for "error"?
