MLB Fielding Percentage Is Broken

In MLB baseball stats, fielding percentage or fielding average measures the percentage of times a defensive player properly handles a batted or thrown ball.  It is calculated by the sum of putouts and assists divided by the number of total chances (putouts + assists + errors.) 

It’s broken.  Example A:  Pirates Catcher Ryan Doumit has a .993 fielding percentage (FPCT.)  Hilarious. 

Remember the 1B experiment?  FPCT doesn’t.

How much does he benefit from catching a large number of strikeouts from the Pirates relief corps?  Well throwing to first base after he drops the ball is a better description as is evident in the 40 assists.  Ryan Doumit is struggling.  Awful last night again.  But one would never know from looking at fielding percentage.
