Doug started writing for RotoWire in April of 2015. His work can be found elsewhere at Baseball Prospectus and RotoGrinders, and as the co-host of the Baseballholics Anonymous podcast. Thorburn's expertise lies on the mound, where he tackles the world of pitching with an emphasis on mechanical evaluation. He spent five years at the National Pitching Association working under pitching coach Tom House, where Thorburn ran the hi-speed motion analysis program in addition to serving as an instructor. Thorburn and House wrote the 2009 book, “Arm Action, Arm Path, and the Perfect Pitch: Building a Million Dollar Arm,” using data from hi-speed motion analysis to tackle conventional wisdom in baseball. His DraftKings ID is “Raising Aces”.
