Jeff Sackmann and Tom Tango have given us permission to combine and release complete files of 1901 to 2015 Marcel projection data to the public. Sackmann’s Marcels are used from 1901 to 2009, Tango’s were used for 2010 to 2012, and Sackmann’s code was used to create the 2013 to 2015 values. There are 2 zipped .csv files, one for hitters and one for pitchers. We have imported and combined the data for export. Jeff Sackmann and Tom Tango cannot verify the data since we have combined it. If you have any issues please comment on this website and we will answer your questions as best we can.
