William Hulbert had an idea. I mean, probably more than one, but one that really took off. And he made that idea a reality 150 years ago this week when he and seven other owners got together and founded the National League of Professional Baseball Clubs to replace the National Association of Baseball Players. It wasn't felt at first, but Hulbert's innovation was seismic, transforming baseball from a pasttime into big business. On this auspicious anniversary, Mike and Bill look back at Hulbert's life and his brainchild, and how he nursed the league through its infancy.

Plus, happy birthday to Bake McBride and Candy Jim Taylor!

And farewell to Steve Hertz, Tim Harkness, Mike Campbell, and Greg Thayer.
