Bud, not sure if this has since been fixed as it is in v25 I am seeing it, but just check
Johnny Dickshot (what a name... and, as if he needed it, his nickname was "Ugly") for a bunch of spurious minors pitching lines. Even that 1930 Dubuque line seems wrong, BBRef only has him as a position player other than for one game with no stats in 1939.
Thx
