From the current RMY auction, here's Bay Area native (b. San Mateo, d. San Bruno) Tom Casey, fresh from the 'Frisco sandlots (after a brief failure with Vernon three yeas earlier) trying to win a spot with the defending champion Cincinnati Reds at Spring Training 1920.
Tom doesn't make the team, but he does get about half a season's work with Terre Haute in the 3-I League before heading back west.
