Jeff Luhnow, now the Astros’ general manager, was a crucial front-office executive of the Cardinals from 2003 to 2011. Luhnow was know for his “Moneyball” philosophy, credited for developing one of baseball’s top minor league systems in St. Louis.

Luhnow was hired by the Astros in December of 2011 and began unconventionally and successfully revamping Houston’s baseball team. Investigators believe Cardinals officials studied a list of passwords used by Luhnow while with the Cardinals, using those passwords to hack the Astros’ system.
