Photo Located John W. Bates 1889 Kansas City Cowboys
Thanks to cinemaodyssey, I was able to locate a photo of John W. Bates, who pitched for the 1889 Kansas City Cowboys.
He is pictured in a team photo of the 1888 South Bend club. The photo appeared on ebay some time ago and cinemaodyssey saved the image.
The photo has a year of 87 on it, but the presence of Jim Tray and Billy Hart in the bottom row suggest it is the 1888 squad. The roster on bb-ref confirms it.

John Bates is currently listed sans first name on bb-ref's South Bend roster (2 Bates are listed, but this appears to be a mistake), but notes in the 1888 papers in Rockford confirm it is the same guy and it is indeed John Bates who appeared for South Bend.
