Graham.... I will look through my holdings on sport. I do not recollect finding any references to Kansas regiments playing baseball or any other sport unless an occasional snow-ball fight. Lot's of mention of jayhawking, which does not classify specifically as a sport. I may also have read of a horse race or two.
I will look. Most of my gatherings of material have to do with Lane's Brigade (3rd, 4th, 5th Kansas) and the 10th Kansas Infantry.
You have lots of varying interests in this area. What is your motivation? I certainly applaud your knowledge and enthusiasm.
