I've been trying to think of ways to find accurate "similar hitters"- kind of like a similarity score- but narrowed down to the type of swing a player has.  I spent the last couple of days organizing data from fangraphs into Excel.  I found all active MLB players with at least 700 career plate appearances (as of last week) and found their career BB%, K%, LD%, FB%, GB%, HR%, HR/FB%, and handedness.  

Take a look here.

This is a lot of fun to play with.  I wonder how much a player's "swing type" factors into these numbers and how much of them is related to how pitchers pitch them...
