Adam Dunn is batting .137 entering play on May 13. How can I possibly claim he's not in a slump?
Well, just for fun, let's break down Dunn's numbers -- month by month -- since he joined the Sox. For purposes of this exercise, we'll evaluate Dunn's play by using one old-guard statistical measure (batting average) and one new-wave statistical measure (OPS):
April: .160 avg., .567 OPS
May: .204 avg., .743 OPS
June: .136 avg., .498 OPS
July: .145 avg., .546 OPS
August: .155 avg., .441 OPS
Sept./Oct.: .128 avg., .508 OPS
April: .231 avg., .881 OPS
May: .230 avg., .976 OPS
June: .181 avg., .770 OPS
July: .211 avg., 788 OPS
August: .176 avg., .691 OPS
Sept./Oct: .200 avg., .676 OPS
April: .148 avg., .617 OPS
May: .103 avg., .316 OPS
In 13 1/2 months as a member of the Sox, Dunn has a .179 batting average with a .683 OPS. You have to give him one thing -- he's been consistent from month to month in compiling these sorry statistics.
You'll note the bolded figures in April and May of 2012. Dunn's career OPS is .863. Those two months are the only two during his time in a White Sox uniform where he has met or exceeded his career OPS.
Dunn's career batting average is .238. He has yet have a single month where he has equaled or exceeded that figure as a member of the Sox. Forget about hitting career norms over the course of the season. He hasn't done it for even one month.
Where am I going with this? Well, I'm saying that anyone who is hoping for Dunn to bat .238 with a .863 OPS probably has a long wait. He's not that player anymore, and the last 13 1/2 months worth of data shows it. When a player has played below career norms for 13 1/2 consecutive months, that's not a slump. That's evidence that a player is simply washed up.
You could argue Dunn is slumping because his May 2013 numbers are poor even by the low standard he has set with the Sox. But for the most part, the lousy hitter he is today is more than likely what you are going to see until his contract finally expires at the end of the 2014 season.
For the Sox and their fans, you've got 289 more games to watch the awful mess that is Adam Dunn.
