As a follow up to Bill Chuck's previous post on Adam Dunn of the Chicago White Sox, a reader asked to look at his struggles against lefties. There are two major changes that help account for his poor performance.
Pitchers are attacking Dunn more when the count favors the hurler. From 2008-2010, Dunn tended to see pitches away when he was at a disadvantage:
Now they are busting him inside.
From 2008-2010 Dunn hit .159/.177/.270 in that situation for a wOBA of .194. This season, he's hitting .000 across the board.
The second change is one that might explain why pitchers are willing to pitch him inside.
Adam can't hit the ball that far any more. There may be many reasons for his, but since his distance dropped against both right-handed and left-handed pitchers, it may be Adam more than the way he's being pitched. Given that opponents are more likely to pitch him inside, it seems Adam lost some bat speed. Maybe a lighter bat will help, but it could also be that at age 31, like Pat Burrell, he physically lost part of his ability to hit.
