Not sure on ball field location - I'd have to look at the Sanborn maps maybe or find where the old Fair Grounds were. That area has grown up a lot.
There has to be a photo of this game out there somewhere. Too big a local event not to be photographed.
There's a 1916 Spring Training Joe Jackson photo on this link. Also a good 1917 Team Spring Training photo showing the split squad uniforms of that year, similar to what the article describes.
