Within Mark Berman's piece on Happ's agreement, we get this note:
Meanwhile, the club has no comment on the departure of Charlie Norton, the Astros director of baseball research and analysis.
Norton is the second long-time Astros employee to leave in as many weeks.
I had never heard of Charlie Norton, but he had been with the Astros since 2002, and in his current position since 2009. Interesante.
