So who was this guy and how did he earn the nickname that has me more curious than a sloth of bears circling a trash bin?
As I was preparing this mornings Blog Kiosk I came across a Dodger birthday of a former Brooklyn ballplayer that I had never heard of... But I should of, 'cause with the kind of nickname he bears this lad should be a part of Dodger lore.
His name is Fred Mitchell Walker, and he is more interestingly known as either "Mysterious Mitchell" or "Mysterious Walker."
As the story goes, Fred showed up one day pitching for the San Francisco Seals of the Pacific Coast League towards the tail end of the 1910 season. At the time he gave his name as only Fred Mitchell -- striking out his real last name of Walker. But that's not the most mysterious thing about him. From what I understand, he refused all interview request, did not pose for photographs, and according to one report (link here) pitched with a mask on.
