Batter Stance(for switch hitters)


Definitions:

Span - Smoothing parameter for the data. As the span value is lowered, more fluctuations in the data data can be observed. If the value is lowered too much, too much noise will be added to the values. Generally the value should be between 0.25 and 0.50.

Angle - These values designate what part of the field the ball was batted towards.
-45 is the left field line
0 is dead center
45 is the right field line
Due to some inconsistencies in the data from stadium to stadium, a user may want to increase the values to -50 to 50 to get all the batted ball data.

Min and Max Distance - These values limit the range in which batted balls are examined. 150 ft is used as a general cutoff between balls hit to the infield and the outfield. I would keep the Max Distance value around 1000 or less because incorrect values existed in the data and setting it to 1000 eliminates these unwanted values.

Overview - The data is collected from MLB with the x-y coordinates converted to a distance (feet) and an angle. The location of each ball is where the ball was fielded, not where it actually landed. I know that the data is not ideal, but until Hit FX is available, it is the best/only freely available data.
