WAR vs WAA Pitchers 2013

This post will compare WAR and WAA rankings for pitchers in the 2013 season. The only team analyzed in WAR vs WAA comparisons was CHA (Chicago White Sox) so those pitchers will be excluded from the pertinent stats table.  As mentioned in the previous post, WAR and WAA values are included in the pertinent stats table for informational purposes.  They are very different numbers with much different ranges.  This analysis compares how each system ranks players using their own values.

WAR overrated or WAA underrated?

This posts takes the top 50 ranked WAR players and lists the biggest differences with WAA ranked players. Thus, WAR thinks these pitchers are highly valued, WAA not so much. It is interesting to note that the differences for pitchers aren’t as great as the differences for batters in the previous post.

WAR underrated or WAA overrated?

The next table shows the biggest differences with the highly ranked WAA players (less than 50) and WAR.  It is interesting that with both pitchers and batters in the previous post, the differences between WAR and WAA are much less with highly ranked WAA players.  In other words, WAR agrees more with WAA when WAA is ranked higher than WAA agrees with highly ranked WAR.
