Data From Legs Aims To Aid Pitchers’ Arms -
The Rockies are one of two teams in baseball that are using Sparta Science to try and predict which pitchers are at a higher risk of tearing their UCL. The team has been a Sparta Science client for three and a half years, and are part of a client base that includes the Golden State Warriors, Cleveland Cavaliers and Atlanta Falcons. The theory behind the work they do for the Rockies, as well as the Padres is that a pitcher who doesn't use his legs correctly puts more stress on his arm, increasing risk of an elbow injury. The team is able to use this technology with everyone, not just their big league team, thanks to a portable force plate. I won't summarize anymore of the article, but it's an interesting theory that actually makes a lot of sense and will hopefully allow the Rockies to minimize the number of serious elbow injuries that pitchers in the organization have to deal with.

Hurdle brings a unique perspective to the challenges facing Walt Weiss, thanks to his seven year stint as the manager in Denver.
