Welcome back to our 30 for 30 documentary short series.

Each year, everyone from front-office executives to sports-radio callers ridicules the logic of the MLB schedule. Complaints aside, putting this together is a daunting task: 30 teams, 162 games a year, cross-country flights, night games, day games … you name it. So, who manages all of this? For almost a quarter-century it was the husband-and-wife duo of Henry and Holly Stephenson, two math and computer whizzes who did it all with nothing but a pencil and a piece of paper. This film is the story of how the Stephensons landed their first MLB contract and became The Schedule Makers.
