The Diamondbacks hire Tony La Russa advisor Dr. Ed Lewis to head their analytics department:

Lewis has been a trusted ally of Chief Baseball Officer Tony La Russa for more than 30 years, collaborating on many projects, including that as a special assignment scout during the Hall of Fame manager’s tenure with the St. Louis Cardinals. “Ed gave me my first introduction to advanced analytics when he worked with our offensive preparation in St. Louis and I’ve always been impressed with his intelligence and integrity,” said La Russa. “It was clear that Stew and Derrick were also very impressed by his wealth of knowledge. He is a scientist who is mathematically inclined and he knows the game. Most importantly, he understands our approach to it.”

He sounds like a very accomplished person.
