If you love history and statistics on the game you will enjoy perusing Alan M. Nathan’ edu site ‘The Physics of Baseball’ from the University of Illinois.
Here is an article on Statcast, the MLB tracking system I enjoyed.
At the Sloan Sports Analytics Conference in Boston on March 1, 2014, MLBAM made a presentation about a new tracking system that will effectively track everything on the field: the pitched and batted baseball and all the players.
Although not officially announced, it is my understanding from discussions with people in the know that the new system is a merger of radar and video technology, taking full advantages of the strengths of each. Doppler radar is the natural technology for tracking the baseball.
Video is the natural technology for tracking the players on the field. Together, they offer a powerful tool that has the potential to revolutionize baseball analytics.
The new technology is a partnership between Trackman for the Doppler radar and ChyronHego for the video. The new system was installed at Miller Park in Milwaukee, Target Field in Minnesota, and Citi Field in New York for the 2014 season.
It was also used for the 2014 All Star Game and extensively used during the 2014 postseason. A rollout to 29 USA parks (with Toronto still under discussion) is expected for 2015.
It is still not known how much, if any, of the data will be publicly available.
